Well I'm back to ask another question and the question is why does my Jeep begin to run hot when I have the A/C running on idle? I changed the radiator hose so now it doesn't do it for about the first 15-20mins that the car is running.

 

i would look at the fan clutch and the aux fan. typically if you are running hot at idle it would lead to the fan clutch.

 

Yep, especially if your jeep cools down again once you get moving.

OP: If you can post a video of the fans when the Jeep is hot (and idling) it might help people work out if the fans are working correctly. Sometimes the main fan can be spinning fast enough to look OK but in fact the clutch has gone and the fan isn't really doing any work.

 

the fan clutch and the fan have both been replaced. Still doing it

 

When ?


Does aux fan come on when Ac is on ?


And does it cool down when cruising ?

 

the aux fan doesn't come when the act is on and yes it cool once again when the cars in motion l

 

Sounds like the relay for the aux fan is not working.

 

Heres your problem . When was last known time it did.

 

Does ac blow cold ?

 

the last time was yesterday and the av blows cold air.

 

@tosterknight can you tell me where the relay is?

 

Under hood passenger side theres a long black rectangle box take lid off look under lid for cooling fan relay location .

 

You can test it by swapping it with another relay that is working.

 

All your toaster...you have the podium ...

 

Here's the relay
