View Full Version : LT1 Exaust manifold plastic caps

My plastic caps broke of the Exaust manifold. Does anyone have any idea how to get those caps out?

I would use the blade of a hack saw and gently cut the plastic then try to try to pry it out with a small screw driver... I assume you are talking about the hose connectors that lead to the thermostat housing.

Or you can use a heat gun to soften the plastic and then also gently pry out. ...IMO

I stripped the nut or whatever you want to call it when I was pulling mine off of the old manifolds. After that, I drilled a hole through the plastic and was able to turn them out with a screwdriver. If I remember correctly, the replacements were around $3 each.

Did the entire cap break and you only have the threaded part still connected to the manifold, or will my method work for you?
