Question about 1990 Toyota Cressida
I have a 1990 Toyota Cressida that is geting to hot , I replaced the thermostat and the coolant is fine, and still having the same problem, I took it in and they said there is nothing wrong but the fan clutch needs replaced. so I did that and still gets to hot ! now I noticed that there are 2 more smaller fan that are mounted behind and in fron of the radiator, are those my secondary fans that are suppose to come on automatically when the car gets too hot ? cuase they are not or do they belong to my a/c it does not sound right to me Help !!!
Replace the radiator, more than likely it is plugged

OK TEST OR REPLACE THE RADIATOR CAP THA'S one of the most never check or replace items in the cooling system by mechanics also if this not take care of your problem i recomend you to take the radiator to a radiator chop to have it clean or replace it becasue all radiators looks clean but they acumulate all the garbache at the lower side becasue garbache acumulate there by grabity and this is hard to diagnose, after doing all this make sure to bleed any air from cooling system
but do not skeep any recomendation starting with the radiator cap.

Hello and welcome to FixYa!
If you have overheating problem, it can lead to multiple
issues. You may be running on low coolant that's why the vehicle overheats. If
that's the case, please add coolant and make sure that it sits on the right
level, too much coolant can cause overheating too for coolant will overflow.
The vehicle may have a faulty or worn out radiator blower
motor that's why it overheats. If that's the case then you will need a blower
motor replacement to resolve the issue.
If the radiator is clogged with dirt and rusts this issue
occurs too. The coolant doesn't flow normally on the cooling system if it's
clogged. If that's the case, I strongly suggest that you have the radiator
flushed to drain out dirt and rusts. If you think that the radiator served you
enough then it's better to have it replaced.
Please do check the radiator hoses, If you have worn out
hoses it can cause coolant leakage which can result to overheating. A tiny hole
is good enough for the vehicle to overheat.
A faulty thermostat sensor can cause the issue too. If you
have worn out thermostat, the fan may not trigger that's why the fan won't work
when under stressed conditions. A blown radiator blower fuse can cause this
issue too so I suggest that you check the radiator blower fuse and replace it
Hope you find this information helpful enough and thank you for using FixYa! Have a good one!
