I own a 2000 chevy s10 LS, 4.3L, manual, a/c........ I opened my radiator cover and the coolant is so gummed up and clogged up to the cap, i have never seen this before. very bad, i have no issues with over heating, YET LOL, and my resivoir is empty as well. I suppose i should do a big power flush of rad engine and heater core, I wondered if i were to use a shop vac and try and suck out this plug of grim. so that i could access the rad to perform this . or should i just bring it to dealler and have a power flush machine oput on. i really wish i could attach a picture. if you have any suggestions please dont hesitate to answer.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Dale, I would take it to a shop and have them use the machine to flush it. Then you need to find out what caused this problem so it doesn't do that again. I'm so surprised you haven't had overheating problems. Lori Johnson
