I have very little heat in my Camaro, and i know that the heater core is partially plugged. Any other suggestions, other than disconnecting the hoses and running a garden hose in the opposite direction? I did this once with my 95 Impala, and was pretty surprised as to what came out when i did it. I am a little nervous about putting a little too much pressure to it. I dont drive it tons when it gets cold out, but i would if i had decent heat. I took it to the mountains last weekend, at that was a huge mistake....lol. I didnt think it would be that bad, but it was.
