My friend just called me to ask if i may know what may be causing his car to overheat.

heres the scoup:

Car doesnt overheat while cruising on highway even with a/c on.
once car comes to a stop / idle it begins to go up.

he checked the fuses, relays and they are all good. We're thinking its the thermastat but not sure.

what can the potential issues be?

theres a honda dealership by his job so if its a relay or something he'll go buy it and swap it out.

 

If it is the thermostat that should be pretty easy/ cheap to replace.

 

cool...im going to call him and tell him to look into that.

 

thermostat and/or fan.

 

Does his fan(s) run when he's stopped & idling? Seems to me more likely to be a fan problem. Specifically a bad fan switch that fails to tell the fan to run.

Here's my thinking...
The engine makes WAY more heat when you're actually driving, so that's when a bad thermostat would most likely cause trouble.

When you drive, even 15mph, there's plenty of air pushing thru the grille so you don't need the fan to run. It's only needed when you're not moving.

 

in the past we replaced the fan which caused an overheating issue but until now its never been a problem. I havent seen his car yet as he stayed in princeton NJ he didnt want to take the chance of driving back to queens. He's gonna drop off his car at a local pep boyz so ill keep you guys posted.

 

:werd:

seems like a no brainier to me, no airflow=no cooling

 

so then how about i ask him to contact you and you fix it....after all its a no brainer ehh.....
