freeze plug

1. How do you change a freeze plug on a 1999 jeep cherokee 4.0?


2. Do you have to pull the motor?

Can you see it? If you can, then no.

You can buy the rubber expanding plugs at the parts store.

A 4.0 should be one of the easiest engines to replace a freeze plug on. As Joe said, as long as you can see it. I wouldnt put one of those expanding rubber plugs in anything. They are expedient, but not worth having to replace again in a few hundred miles. Get the original equipment core plug and put a little black rtv around it before you install it. If you havent gotten the old one out yet the easiest way to do so is to take a chisel or flat tip screwdriver and punch it into the block and use a pair of channel lock pliers to grab one of the lips and pull it right out.
Hope this helps ya,
Billy

if a rubber freeze plug was so good, the dealer would be installing them---and we don't!


replace it with the right part and change your antifreeze more often, it's cheap too.

Lol.

I'd agree, but some of those buggers are hard to get to. The rubber acorn expansion ones can be installed over the beat up one.
