Frequently asked questions

What is the Core Plug (277496) used for?

The Core Plug is a threaded blanking plug that seals a redundant port in the engine block casting on the four-cylinder Series engines. It screws directly into the threaded boss and should be fitted with a suitable thread sealant. It blanks off an unused heater or access aperture in the block.

What's the difference between part 277496 and 527269?

527269 is listed as the alternate part number for this Core Plug, so the two cross-reference to the same threaded blanking plug. If your records or the old plug show either number, this part covers both. Match the thread to the boss in your block before fitting.

When does a threaded core plug need replacing?

Replace the Core Plug if it shows corrosion, weeping around the threads, or thread damage. As a blanking plug in the block, a failed one can let coolant or oil seep from the port. Clean the boss threads and use fresh thread sealant when fitting the new plug.
