i know mine is shot and have been told that it's empty due to a leak. any ideas in how to trace down the busted component or line?
94 ZJ, I6
hey steve, i own a '94 zj i6 and i've noticed it just don't get cold when the a/c is blasting. i've blown hoses sitting at idle before plus i've had leaks prior to the blow out. i'd reccomend having the dealer take care of it. they use a dye that shows up under black light and its no more magic! they locate the leak and usually its the pressed fittings (hose + metal flange fitting with a open end wrench nut on it). having dealt with hydraulics before these hoses are not something you twist and tweak while the systems under pressure to check. "don't rub your hand down the hose while under pressure either" the high pressure air can penetrate your skin or worse cut through it before you know it (just like hyd fluid). my zj is going in the shop on payday.
? for you.... how many miles do you have on it and have you changed out your cat converter? i've got 130k and i've noticed a loss in power and i've been reading on here that with that kind of mileage the back pressure that can come from a faulty cat is bad for the motor. plus a big loss in fuel economy!! i'm fishing for answers or someone else with common gripes that maybe can lead to a fix. my control arm bushings are bad too and need to be changed. the suspension just don't absorb the drunk bumps or reflective things on the road anymore, this is at 25mph and i have to slow down. i think my dash is going to fall into my lap!
anyone else who has input for steve or i please respond!
