I think they are for the rear heater
Yep, rear heater. How are you not leaking coolant? Anyone know?
thank you guys, the rear heater has not been producing heat for a lot of years but I didn't bother because its not important. the thing that bothers me though is that no one mentioned to me that these were hanging since probably 2007, ive brought it at least 20 times to a garage since then...
Time to find another garage... assuming it was up on a lift.
He may have known what it was, saw it was by-passed, and assumed the owner knew what was going on. I don't think it is that worthy of reporting. No safety or performance issue.
