Frequently asked questions

What does the C315 plug do?
It's a core plug, also called a Welch or freeze plug, fitted to the engine block or cylinder head. It seals the core holes left in the casting after the sand cores are removed during manufacture.
When should core plugs be replaced?
Typically when they corrode, weep coolant, or as a matter of course during an engine overhaul, since they're cheap insurance against a coolant leak once the engine is back together.
How many core plugs does an engine typically have?
It varies by engine, usually several around the block and head. Check how many are corroded or leaking on your engine, since it's common to replace all of them together during a rebuild.
