Question
QUESTION: i have a 66 pontiac with a 389 engine its been sitting 4 ten years i put new radiator thermostat water pump got new timing chain distrbutor radiator hoses it keeps overheating the oil is clean dont look like heads or bad some say i just need 2 drive it please help
ANSWER: Hi q:
Since it was sitting for 10 years and you now have it running, I guessing you followed the recommended procedure for bring it back to life? 10 years is a long time to let a car sit, so I'm assuming you flush out ALL of the fluids (oil, radiator, transmission, etc.).
If it's over heating after replacing the thermostat and hoses, it sounds like you have some blockage in the engine coolant channels. So, you you didn't flush the radiator, please do so. This will determine is blockage exist and should push it out.

QUESTION: i had it flused but still overheating out the over flow went 2 put some antifreeze in i today it was a spider in the radiator think i need 2 flush again
You should make sure anti-freeze and water flows through it freely and you flush should be a high-pressure flush to check for small leaks around the head gaskets, radiator and the hoses. The radiator itself could be the problem. Make sure air can get to it and that the vents are not bent to badly. If they are, you should take a flat-head screw driver and straighten the vents one by one.

I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis.
