Default Teflon sealant on any bolt with threads going into
Michael C Henry Mike any coolant bolt should have teflon sealant on the threads. Any bolt that goes into a wet location on the block, head bolts, water pump bolts, intake bolts, nipples for coolant. I also add a thin coat of sealant where the bolt seats. Some RTV will break down over time and start to leak from that hole. If the nipple is going in for life I use black pipe sealant and let it setup for 24 hours. I have never gotten a leak from that location again. You will also need to add about 5lbs more torque to get to spec because of the drag of the sealant on the threads in the hole. REMOVE and extra that may squeeze out from torqueing. Rick L.
