What's your take on taking off thermostats?

My car is from Japan and it has a thermostat (not sure if cars sold in the Philippines also have thermostats). It sometimes overheats and I'm thinking it's because the water does not circulate. I say this because I check the radiator and reservoir everyday and sometimes the amount of water in the reservoir does not decrease. It should decrease because the radiator cap is broken so water leaks from there (haven't had the chance to find a good replacement yet). That is why I check everyday. I pour distilled water in the radiator and reservoir every morning.

The mechanic suggested to take it off since we don't need it in our climate. A lot of mechanics suggest that here in the PH.

After the mechanic took off the thermostat, my car's engine temp is at the 0-20% when I start the car. The other night, I drove it for a couple of minutes and the temp did not go up because of the wind and also the fan was on.

I read in some articles that it can actually hurt your car and the fuel efficiency if the engine is cold.

What do you guys think? Should I just leave the thermostat taken out?

TIA!!

thermostats in cars:
1. enable the car to reach optimum working temperature faster. engines consume more fuel when they are cold.
2. helps conserve fuel; and
3. help decrease air pollution.

the engine temp does not go up fast, when the thermostat is removed. the radiator is cooling the water that is circulating into it from the engine block. normally, the thermostat blocks cold water in the engine block from going to the radiator, where it is cooled and prevented from heating up the engine block. this is the mechanism how thermostats enable engine blocks to reach optimum working temperature, faster.

is your car locally sourced?
if it is grey market, perhaps its thermostat is not the right one for our climate.

another possibility for your seeming overheat problem, is that your thermostat is defective and needs replacement.

perished radiator cap? replace it, po! magkano lang banaman yan...
trouble-shooting will be easier, with one less problem to consider.

good luck.

Another erroneous myth.
The boiling point of water in Canada is the same boiling point in Manila. It all depends on the altitude and barometric pressure. Whatever happened to what we learned in high school? Did all the basic lessons learned change or disappear?

Thanks! All these info are very helpful.

My car is imported from Japan. Binili sa Subic.

That is what the mechanic said, that it's not right for our climate. Fellow car owners who have the same type of car advised me to remove it as well but I am worried about the engine and the thermostat might not be easy to find. I've asked around our Facebook group. I haven't gone to Banawe though.

I don't think the thermostat is the problem. The water is leaking because of the radiator cap. But you're right.. fix one thing at a time to know the real issue.

Some background story on the radiator though.. I have had the radiator changed and the new cap that I bought for our old radiator does not seem to fit well with the new radiator. I contacted the radiator supplier and I would have to go visit them to get the exact one fit for the new radiator. I've been busy the past weeks so I couldn't go there that's why I haven't replaced the cap. But soon.. I promise! [emoji28]

The car was imported from Japan and it was bought in Subic. With that info, what would you suggest? Change the kind of thermostat to fit our climate?

Appreciate all your input!

Just put the same OEM or comparable thermostat. You can get the fail safe one, meaning it will stuck open when it fails. On most modern cars, the check engine light will lit when the coolant temperature sensor senses abnormality on the cooling system. The altitude wouldn't matter, what if you're from Manila and bring your car to Baguio? do you need to change your thermostat?

unless the radiator dealer will give you one for free,
an ordinary reasonably-stocked auto parts store nearer your place of haunt, should have the correct size radiator cap that you need.

while driving around without a thermostat is not really fatal, i would have one installed in my car.

and oh! check the aux fan (if any). it might need replacement.

ano ba car nyo, po?

[ziggyzagged]

I would definitely feel better with thermostat on fuel efficiency wise.

Update: I am finally here at the radiator shop! They said the cap isn't the problem but I will still buy since nandito na rin lang ako. Unfortunately, it's not for free. Their recommended one costs P400.

Anyway, they said the problem might be because there's too much pressure in the radiator. And that pressure build up is caused by one of the fans not spinning in the right direction. It's blowing air out instead of in the engine. So the heat is too much which caused too much pressure. We had the fan replaced and the wiring might not be correct to cause the fan to move in a different direction.

HAHAHA!!!

sorry. it's just, i would have thought that wrong-rotation problem is something that is so obvious to...

i hope your problem is cured, finally.

400 bucks for a radiator cap.
i bought mine for less than 200 bucks. and it's still ok after ten years.
but "originals" have their allure...

I have similar issue with the radiator fan blowing the opposite direction after replacing the non working fan. My electrician just switched connections between the two wires from fan motor to reverse the electrical polarity (+,-) and did correct the issue right away. Hope this helps.

Yes! I wonder why our mechanic didn't check! And i had no clue!

Yes, I do hope soq. This is costing me $$

Anyway, thank you for the help!

The fan has been fixed. They did change the polarity. Thank you for the advice! [emoji106][emoji106]

It was imported from Japan, bought from Subic.

Might be. I don't understand either. Everything was working fine before. We've had the car for nearly a decade now, I think. (Although it was left unused for 3 years)

I think I would put the thermostat back (when I find a new or surplus one).

Thanks for your input!

Bro.,- atmospheric pressure depends on the altitude..

Pero, hindi naman ganuon kalaki ang epekto ng altitude sa boiling point ng tubig...

Parang 1degC [lang] ang ibinababa for every 1,000 ft.... So, not that significant...

Parang mga kotse rito sa atin,- pwede mong gamitin sa Maynila o sa Baguio o sa Sagada,- na hindi mo kailangang magpalit ng thermostat....

Engineers do make mistakes so does doctors. We're all humans, but before the car goes in production, it went through research and development. Whatever the oreeeginal thermostat opening temperature, follow that regardless your car is to be used in Nairobi or Vancouver. Uneducated advise by your mechanic or parts replacer should be verified by a competent and experienced technician.

Pasensiya na kakasali ko lang dito. Ang katunayan may tanong din ako.
Gaano po kainam ang Valvoline Premium Conventional Oil 10w30 para sa Toyota Vios?
Nakita ko po sa user manual, pwede ang mga sumusunod:
5w30
10w30
15w40 and
20w50

Maraming salamat po sa mga makakapagbigay ng honest na sagot ayon sa experience nyo po.

[chronicle]

Best 5w30
Worst 20w50

So in between is fine.

Maraming salamat!😃

Okay sa iyong pananaw, okay na ang conventional oil? Sabi mg mekaniko huwag na akong mag-synthetic. Ang mahalaga daw yung regular na oil change.

Salamat muli.

pwede rin naman. majority of owners kasi they change oil by distance. sa traffic natin hindi dapat distance ang basis. time based oil change interval ang kailangan. example 3-4 months for mineral oil. naka lagay din naman sa owners manual ang tamang oil change interval.

If you use the car regularly, you can opt for the distance traveled option. I did that with my Fiesta running 10k km for around 12 months and I had no issues at all. My ASX is now running around 6900 km since its last oil change (February this year) and Mitsubishi manual requires change oil every 8k km so I have a thousand kilometers to go.\

I use fully synthetic oil by the way.

some of the newer cars are built with extended oci in mind. older vehicles didnt get that luxury... my elantra has one of the shortest oci even with properly spec oils lol. we cant engineer nor go beyond what manufacturers have already set. with oils being more affordable now, for me it just make sense to follow whats recommended.
