I read through many threads on this forum on doing cooling system overhauls. Finally got all the parts that I need. Just removed all the belts and water pump. I was about to install the new WP. However, I don't seem to find anyone mentioning about using sealant or RTV gasket when installing the new WP.
There was no indication sealant was used with the original WP. It looks like the O Ring on the WP should be adequate in stopping water leaks. But the installation instruction that comes with the new WP says sealant should be used.
Anybody has any thought on whether it is a good idea to use sealant or gasket when installing the new WP?
