need help with some problems

[93mkviii]

well today while driving home i turned on my a/c and it was blowing hot air, then about 10-15 mins the engine temp was on the N of NORMAL i have never seen it go that high, and it stayed there for about 10 - 15 min i forgot to check if the fans where running. so any suggestions. i don't even know if they are related, also i checked my coolant its full. thanks in advance

btw this is a day after some lady that nudged me in the back bumper.

Replace the valvestems.


....Kidding. Park the car on a very slight incline, enough to get the crossover cap (located on tube in front of alt.) higher than the radiator. Use a 1/4" ratchet to screw off the cap, let the engine run to warm to "burp" the cooling system. This will get all of the air out of the system, but may need more than 1 try.


That's as much help as I can be, but air in the system is really bad for these engines

So when exactly do i know i have gotten the air out, im guessing open the cap keep the car on for about 10-20 mins and see if it gets hot afterwards, btw is there a reason to why the engine has air(something needs replacing?)
