When I remove the radiator cap...there's seems to be no pressure released. Is this normal? Would I need a new cap? I noticed on someone elses car that when I take the cap off...a little bit of coolants shoots out and pressure is released.

The reason I ask is that my fan doesn't turn out...and I'm about to replace the thermostat and ect sensor. The car doesn't actually overheat...but the temp gauge is always in the middle or JUST under it. Seems like everyone elses car is a bit past 1/4.

 

 

Sounds like it's your radiator cap.. Pop it off and take a look at it. Is the rubber ring swollen out past the metal piece it's sitting on? Is it the rubber ring cracked or missing?? If so, replace the cap.. Here's another thing that will point to the cap.. How is full is the coolant resivoir when the engine is hot?? If it's low, it's not letting out any pressure.. I hope some of this helps.. Good Luck.. And remember, be careful I'm not responsible for any mishaps. Do this at your own risk..

 

actually after a couple days of driving around..the resevoir is really low or sometimes all coolant in there is gone.

how many times have you filled it up?

Well now that we know that your resivoir is empty it should be simple. I believe that it's your radiator cap.. Like I said before, check the cap, it should be faulty. Because this is what happens when your radiator cap doesn't work. You see how the cap has a spring in it? Well, when the coolant in the radiator gets really hot, it builds steam and pressure. As the steam and pressure intensifies, it pushes back on the radiator cap's spring and the piece of metal infront of the spring. As this happens, the pressure is allowed out through the rubber hose and into the coolant resivoir. So if your rubber ring gasket is faulty on the radiator cap, it leaves the pressure no where to go and you end up with a blown radiator. I hope that helps.. Good luck and be careful. I'm not responsible for whatever mishaps might happen..
