Hey guys quick question what is a Thermacker air pump (possibly the wrong spelling) when do they gennerally go out as far a milage is concerned and how hard is it to replace on a 94 gt? thanks.
Sounds like the smog pump to me... Not sure how long until they go out. Mine had 115k miles on it and still worked fine. Few bolts hold it onto the bracket, and theres a few rubber hoses coming out of the back held on by clamps that will need to be taken off... Pretty simple to switch it out/take it off.
