Replacement Radiator Cap Part No: 10227

Replacement Radiator Cap Part No: 10227

I use Advance for a lot of Parts. The online order and parts pickup saves me time. I needed a radiator cap for a 1989 Corolla with 376,000 miles. Their price was competitive, but with a discount for online order, nobody else beat it. I identified the part, ordered and retrieved the part. Installed the radiator cap. It fit much tighter that the old worn out cap. I've driven for a week and haven' seen any more signs of an antifreeze leak. Works as expected.
