How do you replace the exhaust gasket or donut on a 1992 Geo Tracker?

Answer 1

Loosen two bolts on exhaust manifold and replace donut If it's an 8-valve, then it's probable that the exhaust header has burnt through where it transitions from vertical to horizontal just before connecting to the catalytic converter A new header collector can be fabricated in-place at some shops... check around.

Answer 2

You need heat and air tools! Use an Acetylene torch to heat the manifold cherry red where the studs are one at a time and use your impact tool to back out the stud. If you don't heat the metal surrounding the stud enough, the stud will snap off. Be prepared to replace the studs. also make sure the area you heat is greese free and have a water sprayer on hand to put out any unnecessary flames. A heat shield will help. Once the connection is free, pry out the donut. Replace the studs that back out, then insert the new donut.

Answer 3

really you just have to look at it, if you mean that ring on the exhaust, just look at the seam that is leaking and look how it comes apart. typically its 2 or 3 bolts and its off then pop off the old ring, and replace it, then put it all back together. and good as new. PS put some antiseize on the threads before you put it back together, and spray them down with wd40 or something to help get them off easier.

Answer 4

Remove the three bolts between the exhaust manafold and the downpipe. Separate the connection and remove the old gasket. You may have to pull down (a little) on the downpipe to remove the old one. The install is the reverse order of these directions. It should take you about 30 minutes. Its a Very easy procedure.

Answer 5

well that is kinda obvious you remove the first one and then you put the other one on
