Check Your Radiator / Expansion Tank Cap

Over the years I have noticed that many owners never even consider replacing their radiator or expansion tank cap. I have seen some pretty bad ones come into the shop. A bad radiator cap hardly ever leads to severe problems, but it can be the cause of minor coolant loss and drips on your garage floor. The next time your engine is cold, remove the cap and carefully inspect the seal. in many cases you may see cracks in the rubber and a deformed seal as shown in this picture. We carry new caps for most models. They are inexpensive and the easiest do-it-yourself job I know of!

To find our new radiator caps type radiator cap in the search box on the right.
