Got a '97 Chevy S-10 pickemup that is losing coolant from the cooling system frequently. Had a water pump go out a couple years ago, so doubt it's that. Besides which the temp just went on over like it would peg out if I didn't shut down, with the water pump problem.
I note that everytime I stop, I have coolant pool under the right front side, and have to add coolant to the plastic expansion tank.
I'm assuming the plastic tank has developed a leak, down out of sight.
How do I change out one of these expansion tanks? I see there's a flat, black box with fins kind of thing mounted on top of the expansion tank. Is this something for the home mechanic? Or is it definitely a "take it to the shop" kind of thing?
