'91 Camaro w/V6
Owner claims a freeze-plug rusted out in the rear of the block and is
leaking. I'm not familar with the V6. Apparently this plug is at the
back of the block, not on the sides. Other than this problem, car is
in good shape and he's kept it clean. The 'rusted out' part bothers me
since that shouldn't ever happen with proper coolant protection.
Anyways, the price is right and I'm asking how difficult is it to
replace that freeze-plug? This might be a good car for my
granddaughter. Thanks for any advice....
Sounds like it is between the trans and the rear of the block, trans must
come out. Look at the others could be close to the same condition, BTW,
the fact it has coolant in it does not protect agaist rust and corrosion
unless it was flushed every 3 years, this is a 16 year old car.
Good advice, Shep.
Replacing the Welch plug isnt a problem...getting to it is a problem.
And your point on coolant is right on.
Sometimes even if you replace the coolant regularly, you will get corrosion.
If the system is leaky, sucks in air upon cooling, etc no corrosion
package in the world can offset such contamination.
I had a friend who had a leaking plug on an old 60 Chevy Impala in
a similar location. He put in some sodium silicate (water glass) and got
it to stop leaking for a year or so. It is a lame solution, but sometimes
a solution like this can buy you the time you need.
