Changing the Dexcool?

thermostat,

Seeing as how your Dex has been in there for about 3 years too long I'd recommend draining the rad plus yanking both block drains to get it all out, then refill with new Dex. Use DISTILLED water and install a new rad cap.

Doc

Yanking both block drains? Are these screw-in or pressed in like freeze plugs? Where are they?

Thanks a mil, Brian

Yes, it's the only way to get -all- of the old coolant out of the block.

Screw in.

Same place they've been for the last 49 years. Low on the sides of the block. One -might- be the knock sensor.

Thanks, Buddy. A Chevy's the only type of motor I can think of that I've never worked on much. Of course, the reasons are obvious, right? LOL. I like the one about Fords being cheaper to maintain because there are spare parts all over the road...

If you go looking for them, you'll find them considering that there isn't a whole lot of variation in block drains between GM, Ford and Chrysler V-engines.

All the two Fords I owned ever did was shed body parts, and considering that they fell off because of rust, they weren't of much use. That's why I own a Dodge.

From bad to worse...

Not really.

My boss owns a 1995 1500 ram... my father's 1995 caravan is rotting worse. His truck looks brand gnu....
