Overflow / Expansion Tanks

There are a couple of reasons for why you would want to replace your factory coolant overflow and expansion tanks. For example, if you drive any Subaru turbo model, take a look at your factory expansion tank. Notice how it hurts the eyes. Now look at the coolant overflow tank. It is plastic, kind of yellow, and honestly it kind of looks like a medical dispenser of some sorts. The fact is that if you're trying to win a car show, then the factory coolant expansion and overflow tanks are going to hurt your chances. And although they do work and do their job well, RallySport Direct carries a great selection of attractive overflow, and coolant expansion tanks that will enhance that dusty engine bay of yours.

Most of the offerings from RallySport Direct are going to come in an aluminum construction. Some will come powder-coated, and some will come polished. Some are universal, and some are vehicle specific. For example, do you have a Nissan GTR? Replace that boogie man of a coolant expansion tank with the AMS Performance Coolant Expansion Tank Kit. If you drive a Subaru STI, there are several great examples from Mishimoto, COBB, Killer B Motorsport, Moroso and PERRIN among other great brands.

And while you're updating your overflow and expansion tanks, take a moment and upgrade the rest of your cooling system and check out our large selection of radiators, as well as radiator caps and thermostats
