Antifreeze leak at the belt tensioner?
2001 Pontiac Grand Prix, 3800 engine.
I changed the belt tensioner. It's a metal housing about the size of a loaf of bread. There are 2 rubber hoses connected to the tensioner, and 2 plastic plugs that fit into the engine block. The hose ends and plugs all have an O-ring. When I changed the tensioner, it looked like there was some sort of silicon glue on the hose ends and plugs.
The car has an antifreeze leak. I suspect it's coming from one or more of the 4 coolant connections to the belt tensioner.
What do I use to make a leak proof connection at the 4 fittings? RTV sealant? How much?
