Today I had noticed that after I had gotten my car warmed up the radiator was still cold. One of the rad hoses was hot whilst the other wasn’t so it’s obviously not circulating but I don’t know what could be stopping it from doing so. I had changed the coolant from the green factory coolant to the orange Dexcool as I’ve seen it’s recommended to switch to, I had flushed the coolant 10+ times before switching so I don’t think its gelling and the thermostat is about a year old(should I buy a new one anyways?). if anyone can help me on how I should go about diagnosing this problem it would be very helpful as I’ve never had this problem before.

 

Where are you? Fill in your info.

How cold is it outside? Sounds like a thermostat.

 

I live in Florida but the fans make it feel cold but I know the fans aren’t that good if the rad was working lol.
And ok that’s what I’m hoping it is I just ordered one. It’s currently 89F
