Hi everyone, am pretty new in here.
i have gone through the thread and i quite appreciate the contributions.

I drive a 2003 Toyota Camry and i notice the water level in the radiator usually goes down while the level in the reservoir increases beyond the normal level. Lately, i have to check the water level before driving out. Please note that no leakages have been noted in the radiator. The thermostat hasn't been removed and the radiator is single cell.

Mechanic 1 said i should change the single cell radiator to double cell;
Mechanic 2 said i should change the radiator cap;
Mechanic 3 said the top gasket is flat and should be changed

I will appreciate some advice around it as i'm not a fan of trial and error.

Thanks in anticipation of your responses

Also change reservoir cap

This thread is quite expository. Thanks a lot to the major contributors.

I just took my Toyota highlander 2003 to automedics in ikeja for complete scan since I noticed it was consuming much fuel and the road side mechanics have been fleecing me for long with out any result.

After a proper diagnosis,though expensive. 15k.they discovered a lot of things that been done to my car including the removal of the thermostat and the fan running direct,and so many others.

It's going to cost me about 150k now to put everything back to factory setting including the thermostat.

Ignorance and being penny wise finishes most of us and we end up damaging our vehicles we spent a lot to buy.

I came here to read,because some folk out here were still advising me to keep my money and not mind the automedics report.

Good evening everyone here, I’m new here and I’ve been seeing discussions about thermostat, remove and don’t remove, what about the case of thermostat that failed to open to releases water to engine on motion, and you know car owner we always be car owner some of them don’t look at temperature cauge often and the engine encounter overheating and got knock, what do we have to say about that, please I want to lean through this solution thanks everyone

Very educative thread, kudos to the contributor.

What can someone do if you noticed that the coolant is leaking out as a result of erupting, and the car is heating up unnecessary.
