0key: Pls can someone refer me to a place where I can buy a thermostat of rating 60'c- 70'c in lagos or any part of Nigeria? It is very scarce in Abeokuta. Does it mean the demand for thermostat is very low?

0key: i am using camry 2002 4cyl engine. I want to change d themostat(rating 90'c) it came with from canada to a colder thermostat of rating stated above because of the hot weather.

ZIM DRILL:

whats the reason you want to change it ?

90'c is the world average opening for a car thermo whether in alaska, dubai, brazil etc , thats just above the engine operating temperature

60 or 70 your car will be raining on cold and it will burn more fuel and also you might not find 60 or 70 you are looking for

Thanks bro for your kind response. My car occasionally detonates on mild acceleration especially during hot weather at operating temperature of 90'c. I feel if I use thermostat of 60'c-75'c, it will eliminate it. I've done scan and no fault detected. Someone told me to check the EGR valve but i have no idea of it.
Any alternative solution will be appreciated
