Worked for my radiator

Deleted my heater on my c10 and these for my stock radiator perfectly. No leaks or cracks yet.

Fit one side of an fbody ls pump

Good fit. We will see how it holds up after use.

M**.

Recommended. Great product. Good Quality. Exactly as described and expected.

Exactly as expected

This cap worked perfectly to replace the old crusty one causing a coolant leak on my Saturn. Rubber was supple, easy to install. Wish you could buy in packs of one for cheaper though since that’s all you need.

They work

I installed these as a stop gap while I replaced the heater core in my Mustang. They are simply non-reinforced rubber caps, nothing special. I was afraid to use the car because I'm paranoid and I didn't want these to fail and leave me stranded so it made me get the heater core done faster. But they worked fine and did what I needed them to do.

5/8 OD not ID

Good quality rubber cap but 5/8 is the OD not the ID.
