hey guys so my ac works fine but when its really hot oustide, the temperature goes up on the cluster then when i turn the ac off it falls quickly to the normal temp i had the coolant flushed last october does anyone know what it could be? sensor thermosat? i dont want to change everything fo no reason

 

isnt this your 2nd thread on this subject??

Ck passenger side fan operates when ac comnpressor engaged
If not- thats your prob, ck fan for operation,,sensor, relay,,fozen fan??

 

If you have a repair manual on the car, they should highlight testing procedures for the sensors in related to the compressor cooling fan. Check whichever sensor you think might be bad, 01tl4tl named pretty much all sensors that might be faulty. Testing them eliminates have to waste money on a sensor that isn't faulty.

 

whats the results of the testing we sent you to do?

 

the ac fan works both fans work sometimes the driver side fan works after i turn the engine off for 5 to 10 mintues

 

How far up does the temp gauge go? Almost overheating status? And I think 01tl4tl meant the repair manual procedures. I'm new to the site (I just got mine last weekend) but I've had a '91 Accord and did all the work on it myself since I was 16. Point being, even if you don't have a maintenance book, you should be able to find some test procedures on the site!

 

the radiator(driver side) fan should remain on after engine shut off to help cool a hot engine. a hot engine will build up temperature once shut off and sitting still so the fan will run and try to cool the engine down.

according to your description, both fans seem to be operating normally. i think you need to check the sensors. something isnt kicking on when needed or... have you done a coolant flush recently? could be air trapped in your system.

 

driver fan runs more than 1-2 minutes after shutdown means the fan temp sensor is failing
wont come on when needed during drive, then runs forever afterwards

replace that sensor and I bet the temp situation is resolved

look at passenger side bottem corner of rad- it screws in
see local parts store for new one

burp the system when done- make sure heater is on full hot so its contents are part of the flow during burping--it will hide air from you and cause probs!

 

i got a used sensor of my friend and still heated up ill try it with a new sensor this week and could it be my rad i dont think it was changed for a while.
