The needle would start climbing whenever we stopped moving.
Sitting at a light in Battambang, four boys in the back, air conditioning working as hard as it knows how, and the temperature gauge on my 2012 Sienna would begin its slow walk to the right. Get moving again and it settled. Stop again and up it went. I checked the coolant, because that’s the one thing a man knows to check, and the coolant was fine. It was always fine. In two years that reservoir never dropped a visible millimeter, which I took as good news for an embarrassingly long time.
It took two years and a Korean missionary with a socket set to explain to me what was actually happening. And the explanation had almost nothing to do with the coolant, and everything to do with what buying a car in Cambodia really means.
In Korea, I Barely Noticed I Owned One
You have to understand what I’m comparing this to.
In Korea, a car is a convenience. If it breaks, the day continues. There’s a subway that runs to the minute, buses that arrive when the sign says they will, and a taxi you can summon from your phone at midnight in the rain. A dead car in Seoul is a phone call and a mild annoyance. The system absorbs it and you get where you were going anyway.
I never once thought of my car as infrastructure, because it wasn’t. It was one option out of four.
Then we moved, and I found out what it’s like to be the only option.
Here, I Am the Bus
Four boys, taken to school and brought back, every day. Church. The market. The clinic. The road trips that are their own separate crisis.
Then the other half of it. The work is with the local community, and a fair amount of that community is not in town. Deliveries out to rural areas. Going to see a situation for myself instead of hearing about it. Sitting down with people who live a long way down a road that a motorbike and I would both regret. None of that is optional and none of it happens on a bus.
There is no municipal system standing quietly behind me. There is a van, there is me, and there is whether the van starts.
So when it doesn’t, it isn’t a car problem. Family stops and missions stops, on the same morning, for the same reason. It’s a school problem, a ministry problem, and — the part that actually stings — a my wife is now home with four boys and no way to leave problem. This entire household’s range is whatever one aging Toyota says it is that day.
Which is why the vehicle was never a lifestyle question for us. It’s a non-negotiable, and I bought it like one. That’s the thing I’d tell any dad considering a move somewhere like this: where the transport is good, your car is a possession. Where it isn’t, it’s a utility, like water. You don’t feel the difference until the day it’s off.
Buying a Car in Cambodia Is a Budget Problem With Exactly Two Options
Southeast Asia is notorious for vehicle import taxes, and Cambodia is not the gentle end of that. New or used, it doesn’t matter — the tax comes for both, and it’s tiered by engine size, which is its own quiet joke on families. The bigger the engine, the harder the bracket. A van that seats six is a big-engine vehicle by definition. The exact vehicle a family of four kids actually needs is the one the tax code is least interested in helping you buy.
Which leaves you two doors. New, at forty thousand dollars and up. Or used, at anything under that.
Our budget was limited, the way most missionary budgets are limited, and four kids meant a sedan was never on the table. So in 2024 I went to Khmer24 — which is essentially the Craigslist of Cambodia — and bought a 2012 Toyota Sienna for $21,500.
I know. Twenty-one thousand five hundred dollars for a twelve-year-old minivan is not a good deal anywhere on earth. It was, however, a real deal in Cambodia in 2024, which is a different sentence entirely. Buying a car in Cambodia is not shopping. It’s picking the least bad door available to you on the day you need a vehicle.
One thing did go right. The man selling it ran a garage, and his family had been in the business for forty years. Skills and credit, both, in a country where you cannot look either of those up. That was the biggest green flag I had, and I took it.
The Pipeline: Scan at Toyota, Fix at the Garage
Once the registration and the paperwork were done, the first thing we did was drive it to an official Toyota dealership — yes, those exist here — and pay for a deep diagnostic scan.
Forty-nine dollars. They handed me a list.
Then I took the list to a local garage, where a man read it and went treasure hunting for decent replacement parts.
That is the standard pipeline here, and it isn’t a corner being cut — it’s the good version. Scan where the equipment is honest, repair where the labor is affordable.
The reason is arithmetic again. In a country where essentially everything is imported, and imports are taxed at close to double, a part lands somewhere between two and three times what you’d pay for it elsewhere. Dealership labor is priced to match.
Having Toyota do the work on that list would have run four to six thousand dollars, minimum. The local garage did it for eight hundred.
Forty-nine dollars to find out what was wrong. Six thousand to have it fixed properly. Eight hundred to have it fixed. Every foreigner here eventually stands in front of that third number and takes it, because the second number is most of a used car.
I took it too, and at that point it was the right call. But “fixed” in that sentence is doing an enormous amount of work, and I didn’t find out how much until the bills started repeating.
What This Climate Actually Does to a Vehicle
The ordinary problems are all still here. But a year-round hot and rainy country adds its own list, and two of the three were obvious to me.
The air conditioning, first, and not as a comfort item. In the dry season it runs 38 to 45 degrees Celsius here — call it 100 to 113 Fahrenheit — and at those numbers the A/C is not a feature of the vehicle. It’s the reason the vehicle is habitable.
We went a month without it once.
There are exactly two ways to drive four boys across town at 42 degrees with no air conditioning, and I tried both of them. Windows down means dust off unsurfaced road and exhaust out of vehicles older than mine, delivered directly into the back seat for the length of the trip. Windows up means a dry sauna with seatbelts in it.
The boys were devastated. I don’t mean that as a joke at their expense — it’s the one failure in the whole vehicle that they can actually feel. A worn shock absorber is an adult’s problem; they don’t know it exists. The A/C is theirs, and they serve the entire sentence in the back row, where the air arrives last and least.
So it is never off, which makes it the hardest-worked system in the van. Whatever a sensible service interval is where you come from, it is not that here.
The air filters, obviously. Dust in the dry season, everything else the rest of the year.
The rubber — not obvious to me at all. Seals, hoses, bushings, boots, all the unglamorous black parts nobody thinks about. For the first stretch I saw nothing. Then, right around the two-year mark, wear and tear turned up everywhere at once, like the whole vehicle had agreed on a date.
Add the roads. Once you’re outside Phnom Penh, a great deal of road is not properly surfaced, and the suspension pays that bill. I replaced the shock absorbers on all four wheels.
None of that is a scandal. It’s the operating cost of driving a family around this country, and I’d budget for it from day one if I were doing it again.
The Year of the Cylinder
Then there are the problems that don’t resolve.
In July 2025 I had a cylinder issue. It was fixed last month.
I want to let that sit for a second, because the number is the story: a year. Not one long repair — a loop. They diagnose it. They open it up. They change something out. They tell you it’s fine. You drive away, and some number of days later the engine light comes back on. Then you go again.
This isn’t everybody’s experience, and I’m not interested in running down men working hard with what they have. But live here long enough and you meet the ceiling: for anything genuinely complicated there often isn’t a trained professional in reach, and the process becomes elimination by attempt. Slow, expensive by increments, and the specific hurdle almost every foreigner here eventually hits.
The Korean Mechanic
What finally broke the loop was a connection — a professional mechanic from Korea, here doing Business as Missions — running a real trade as the ministry itself, which is a step past the older tentmaking idea of working a job to fund the work.
He opened the hood and was visibly shocked.
Inside of a week he had it fixed. Most of it, anyway. He stopped partway through and came to find me, because he’d hit so many sketchy leftovers from previous repairs that he didn’t want to keep going without my consent.
The wiring especially. Cut wires. Mixed wires. Things spliced to other things for reasons no longer recoverable. Whole systems in that van had simply not been running, and I had been driving it every day without knowing which ones.
He told me the van would not pass an inspection in that condition, because technically it was only half a car.
I have owned this vehicle since 2024. I have driven my entire family in it, on those roads, for two years.
The Thermostat
Then he told me my engine didn’t have a thermostat.
Not broken. Not stuck. Not there.
I asked how that happens, and got the most Cambodia answer I have ever received: mechanics here often just leave it out. Thermostats fail, and a failed one has to be replaced, and a part that needs replacing on a schedule is a recurring problem nobody wants. Remove it and the problem goes away. So it gets removed, nobody mentions it, and the car drives off.
In a country this hot, that means an engine running with no temperature regulation at all.
I didn’t take that on one man’s word. I went and asked, and got the same answer back from mechanics here in their own words — not defensively, either. It is not a secret and it is not treated as a scandal. It’s just how it’s done, and the owner of the car is simply not part of the conversation.
And there, finally, was my two-year mystery. The coolant that never went down. The needle that climbed every time we stopped moving and settled every time we started again. I’d had a symptom the whole time and no idea it was pointing at an absence rather than a fault.
You cannot diagnose a missing part by looking for a broken one.
Three Doors, and Every One of Them Costs You Something
Buying a car in Cambodia gets you two doors. Owning one gets you three — and this is the decision every missionary and expat with a car here is actually making, whether or not they’ve said it out loud.
Door one is the cheap, unreliable fix. Local garage, treasure-hunted parts, eight hundred dollars instead of six thousand. It is why anybody here can afford to drive at all, and sometimes it is genuinely the right call.
I assumed the catch was reliability and that the money was the part I was winning. That is exactly backwards, and I have the receipts.
By the time I gave up on door one, I had put roughly five thousand dollars into this van. Not in one bill. In a stack of them — each individually reasonable, each one a return trip, each one ending with somebody telling me it was fine. Door two cost me two thousand, once, and it held.
So the cheap door was the expensive door. It just billed me in installments, and it took a year of installments before I could see the total.
Door two is the pricier fix that actually holds. New parts, ordered and waited for, installed by somebody who knows what he’s looking at. The van sits in a garage while a box crosses an ocean, which is a real cost when the van is the family’s transportation. What you buy for that money is not really the repair. It’s the near-certainty that you are not coming back for the same thing. Buy the new part and wait for it. That was the Korean mechanic’s advice and it’s the single most useful sentence anybody has said to me about this car.
Door three is buying new and maintaining it properly from day one. Forty thousand dollars and up, taxes included, and in exchange you start with a vehicle that has no hidden history at all — nothing spliced, nothing quietly removed, no previous life you’ll spend two years reverse-engineering. Over ten years that may well be the cheapest door of the three. It is also, for most missionary families I know, not a door. It’s a window you look through.
I took door one because it was the only one open to me in 2024. I’m on door two now, which is how it usually goes — you don’t choose door two. You get promoted to it by door one, and door one hands you the tuition bill on the way out.
Five thousand, then two thousand. If I’d had the second number available to me first, I’d have paid it first. That’s the whole lesson and it cost seven.
The other thing I’d change is cheaper than any of it. I’d stop treating the forty-nine dollar scan as a formality at purchase and start treating it as an annual physical. Actually, I went one better — I bought a portable OBD2 reader and I scan the van myself now, regularly, not because I can fix what it finds but because I would like to know. In a country where the standard answer is that it’s fine, owning your own opinion about your own engine turns out to be worth about thirty dollars.
“Good Enough” Is the Standard Here
The honest current state, because I don’t want to end on a triumph this van hasn’t earned.
The check engine light still comes on. Some of that is permanent error codes stored from old repairs, and they’ll sit there forever. But the difference that matters is this: now that the wiring has been put back the way it was meant to be, the codes actually mean something. The van tells me the truth. For two years it was a machine full of severed nerves, reporting nothing, or reporting something else.
There’s still work outstanding on the PCM. The Korean mechanic walked me through it, looked at where we were, and told me it could wait — not devastating, not a practical problem, more of an aesthetic one. Come back when you can.
Three of the seats have a broken handle. Three have a broken frame. None of that stops the van from doing the only job I need it to do, which is carry six people to a place and back.
And that’s the thing I finally understood, two years in. Here, the standard of a pass is “good enough.” Not perfect, not restored, not the way it left the factory in 2012 — running, safe in the ways that matter, and honest with you about what’s still wrong.
I’d heard that said about this country several times. I’d nodded at it. It didn’t land until a mechanic told me my van was technically half a car and then, a week later, handed it back to me working, with a list of things he had deliberately not done.
Why This Is a Parenting Article
I have never once heard a parenting talk mention a thermostat.
But a large share of what I actually do as a father here is logistics. Get four boys where they need to be, on the day they need to be there, in a climate actively working to dissolve the machine that takes them. When it works, nobody notices — which is correct. Children are supposed to experience transportation as a fact of nature, like weather.
Cambodia has slowed me down in ways I’m grateful for. This is not one of them. This is the bill that comes attached to the good parts, and I pay it in a garage. Buying a car in Cambodia was one afternoon on Khmer24. Keeping it running has been two years.
So I keep this van running the same way I keep the daily schedule running. Not because I enjoy it, and not because I’m good at it. Because four people shorter than me depend completely on a system they don’t know exists.
These days when we stop at a light, I still look at the needle.
It doesn’t move. That took two years, a family garage, an official dealership, a year of cylinder appointments, a Korean missionary, and a part somebody removed on purpose before I ever owned the thing.
Nobody in that van but me has any idea. That’s the job.
