Please help!!!

I've noticed a fuse missing on my 99 mustang gt and was wondering if any one knows if it for the ac??? And also a wire missing is it for the ac too??? My car always blows hot air. Even when the ac is on. Ummm can the radiator cap have anything to do with that ??? And can anyone tell the size of engine, I thought it was a 4.6L but other ppl tell me it's a 5.4. R 5.3. :s confused lol ImageUploadedByAG Free1372811292.065481.jpgImageUploadedByAG Free1372811304.849322.jpgImageUploadedByAG Free1372811315.794769.jpgImageUploadedByAG Free1372811327.216807.jpgImageUploadedByAG Free1372811341.651217.jpg

Re: Please help!!!

It's a 4.6 if it's original. Owner's manual should give you the fuse identification, but I think it'd be for the convertible top, if yours was a convertible. The missing wire looks like it might be for your temp sensor, but I'm not wholly sure about that. The radiator cap shouldn't have an affect, but if the pressure the cap is designed for is too low, it will lift and you may run high temps. Not enough info on the AC, may have lost it's charge.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

Re: Please help!!!

If you remove the cap, the radiator is at a lower temperature, the water in the coolant is able to boil off. It takes more energy to change the state of the water (from liquid to vapor) than it does to raise it a degree. Therefore, with the cap off, the coolant absorbs more energy in the form of heat from the water boiling off.
