I have a 1999 chevy venture van. In 2004, the intake manifold gasket
leaked and I had it replaced. The mechanic changed the coolant to
dex-kool, a brownish coolant that was supposed to be safe for the gasket.
A few weeks ago, he informed me that the gasket is leaking again.
The van has been well-maintained and has about 85000 miles on it, so I
feel it has some life left in it. On the other hand, I thought I might
save
some money and put in a sealant. One that was recommended to me is
alum-save, and one I found locally is Prestone Stop Leak.
I did an ask.com search and it seems that some people have had big
problems after using these sealants, so I am a little leery of using them.
Can anyone give me some advice about this?
Thanks
