okay this one is weird my car overheat overtime... It is not like i have a leak anywhere but over time it will slowly heat up!! Although I do have to fill up a bit from time to time. I checked my fans and the one on the right is not working. Would that be the problem?

O yea when i am on the freeway and not stuck in traffic the needles will go down

 

How do you test your fans?

 

driver side fan- engine radiator cooling- temp sensor controlled

passenger side fan- ac ON controlled

How is the water pump age? belt condition- tight?
radiator coolant new- less than 5 years old?
radiator dirty inside?
Air bubble in system?


Do a pressure test of the system and make sure no leaks
Check seal on radiator cap

 

^ Good points, also check your hoses for ballooning. If the upper hose is what we call "pregnant", it's time to replace it (and possibly the lower hose) and burp your cooling system to get the air pocket out.

Slowly overheating is likely a failing thermostat. A new thermostat is easy, cheap repair and has a good probability of fixing your problem. Replace coolant if it's over 2 yrs old.

good luck

 

yea i am getting that change out later on today.
