hi,GREAT SITE here. im new to this forum but not to chevy. i currently own a 94 silverado conversion 5.7 tbi 4x4, and i love it, even with the high gas prices i wont sell.

my question is in regards to the thermostat. a couple years ago it stopped working so i swapped it out and that solved the problem. that one just quit working too so i switched it out. however now it still doesnt seem to work.

short of a flush any suggestions?

and if i have to flush it what is the process i thought i heard you are supposed to flush it in reverse? anything you guys have to say would be very helpful.

thanks

scott
