My friend was waiting for me outside a store with AC on (about 20 mins)... when I got out ... coolant all over the ground.
It was over heated, so I turned off the engine, opened the hood, coolant was boiling in coolant reservoir (it was flowing over from the radiator) and its getting out of the reservoir...

wait for a lil for the engine cool down, refill radiator, and go home

On the way home

AC on + going <45mph = over heat
AC on + going > 45mph = ok
AC off = ok


I dont see the left fan (looking toward the car)working when AC on or off, even when its over heated

Im thinking of the thermostat or the sensor but not sure

 

If one fan is not working, fix that fan. Both fans should run w/ AC compressor turning. Is this a 3.2 or 2.5TL. Thermostat may be OK, or perhaps contributing, but fan is definitely bad from your post.

Put year/trim/engine info in your signature line and it's always presented when you post.

good luck

 

I replaced the fan motor just last winter ... I already checked cooling fan fuse and its still good...

Am I just going to order a new motor?

 

Thank you so much Mr. TexasHonda

 

I tested the fan and it worked

I didnt pay attetion yesterday but the upper radiator hose expanded bigger... was it caused by unopened thermostat?

 

Sounds like the thermostat stuck closed and then when the cooling system calls for the fan to come on normally it won't because of the thermostat being stuck closed. Would explain the coolant going back into the reservoir. From my experience only buy the OEM thermostat from Honda because it really does affect the car's drivability.

 

If one fan was running and other fan was off, the off fan is bad regardless of thermostat. Sometimes a fan will run intermittently when the brushes are worn out.

good luck

 

Mr. TexasHonda was right ... I tested the thermostat and it worked...

I replace the cooling fan switch but the fan still doesnt run

Where are the brushes at?

 

I replaced the relay (top right of the radiator) but it still doesnt help

 

I fixED IT! THE FAN IS WORKING NOW!!!!

I replace my radiator couple months ago and forgot to put the cooling fan relay back ... thats why i could not find it and replaced the wrong one...........

 

I feel so damn good right now!!!

Thank you everyone for helping me out!!!

 

Thanks for posting the fix.

good luck
