Title: Radiator Fan running steady
Post by: Jason Walker on June 23, 2023, 10:14:46 PM
So haven’t been on here in a while but in need of some help. Coolant temp is running between 107 and 122C. Fan turns on and runs constantly. Had water pump replaced as it had a hole. Thermostat was replaced. Coolant temp sensor replaced. Took to shop and they had said needs a new radiator fan as it was only running on high. Replaced the fan $$$$. Have cleaned the radiator. Fan runs steady until I turn the Jeep off. Coolant Temp while driving at 100km/hr gets up. Can’t even go through a drive through as cannot hear them due to fan not stopping.

Looking for any advice for next steps because it is draining me of $$$.

What model Jeep are we talking about here? 

Fan will run if your AC is on so that might be something to try (turn AC off see if that changes things).  Also maybe check the fan relay... its possible its failed on.

Hey Jason, I think I might have found my issue. ( Fan not cooling enough)
I will likely cancel my appointment with Calgary radiator in the 12th. Not sure if you want that appointment or not. Let me know.
