I know there are tons of threads on this, but i can not find an answer to my problem in any of them.

I just recently replaced the radiator fans because they were shot. I thought this was the cause of my overheating issues, but my car is still overheating. The top hose is always very hot and the bottom radiator hose is cold.

Anyone have any experience with this. Thanks in advance.

 

First check your coolant level. If the upper hose is hot while the lower hose is cold then your radiator is clogged.

 

You are not flowing coolant. Back flush radiator and replace thermostat.

 

Replace your thermostat. It is not opening to allow flow. Also, verify that your fans are indeed turning on. Don't understand how the car overheats unless the collant level is low. Bought mine with a closed thermostat but didn't overheat. I only noticed because I was not getting strong heat.

 

The fans are definitely turning on, I always check. Also the coolant level is fine. It is very hot in Miami right now so after about 30 minutes of driving it overheats and i have to turn on the heater, it blows extremely hot air.

Can the Thermostat give you the right temperatures and still malfunction by not opening?

 

+1 for this. Also, where are you checking coolant level? I had an issue with a cracked coolant overflow nipple - when coolant got hot it "overflowed" out the crack. The coolant level in the tank always looked OK, but the radiator kept loosing coolant. Eventually, car started to overheat and when I checked it out the radiator was nearly dry! New radiator and everything was fine.

 

You can take out thermostat to see if coolant flow, Or you can just replace it.

 

Check and see if the space between the radiator and the a/c condenser coil is clear and not full of junk.

Check coolant level by removing radiator cap when the engine is cold. The coolant should be completely filling the radiator - no air. If the radiator is full, I would suspect that the thermostat is not opening up like it should.

 

It's definitely full from the radiator. Ill check the thermostat today.

 

I took out the thermostat today and I put in 180 degree water and it did not open up. It seems it was letting a little bit of water go through, but it definitely did not open up. I'll go buy another one and see how it goes.

 

OEM I paid $25. You should seek out one.

 

sucks

 

Ya i bought one today at Autozone and i paid 30 with the seal. I tested it and it opened just like it was supposed to. I'm going to install it tomorrow.

 

I replaced the thermostat today and the car did not overheat with the a/c on blast. I'm so glad to have this problem fixed. Thanks for the input.

 

 

 

I love happy endings!
