I'm installing a new water pump tonight on my 69 351w. There are 9 bolts that hold it on. Are any of the holes wet so that thread sealer is required (feel free to make obvious jokes now)? If so what kind of thread sealer should I use?
Only the ones with - oh, never mind! ;>) I don't think any of those penetrate water jackets. But there a few head bolts that do. Teflon sealer is what they usually recommend on bolts that do hit water jackets.
