my heat isnt hot...its luke warm...i need help...its freezin outside...how can i get my heat hot...its not the core...i changed that...not the thermostat either...i changed that...sum1 told me to bleed the system...how do i do that...its a ls motor in a 92 hatch...HELP!!

 

Check the heater hoses.

 

to bleed the system, when filling up the coolant unscrew the bleeder valve on the water neck untill you see coolant run out untill all of the bubbles are gone. then tighten the screw back up but dont snap it off like i did. now run the car till it warms up with the cap off so that coolant goes throught the t.stat, then cut the car off and fill it back up after loosening the bleeder valve. close/tighten everything up, fill your coolant resevoir and your done.

some one correct me if any of this is wrong
