This gasket basically creates a watertight seal between the thermostat housing and either the intake manifold or the cylinder head – depending on your vehicle. It stops coolant from leaking out where those parts meet. It’s a simple part, really, but absolutely crucial for keeping your cooling system sealed up tight. Think of it as the barrier that keeps the coolant inside where it needs to be, circulating through the engine to keep things from overheating. The coolant flows past the thermostat, and this gasket makes sure it doesn’t escape at that connection point. It’s part of a whole system, of course – the thermostat itself, the housing, and the gasket all work together. If this gasket fails, you’ll almost certainly have a coolant leak. You'll notice if you see a green or orange puddle under the front of your car, or even steam coming from the engine bay. Even a small leak can lead to overheating, which can cause major engine damage – and that's something you really want to avoid. It acts like a shield, protecting your engine from the consequences of losing coolant. They’re relatively inexpensive to replace, and a lot cheaper than repairing an overheated engine. You can find them pretty easily—we stock a good selection at Fixparts Online, or most auto parts stores will have them. It's one of those maintenance items that's a good idea to check when you’re doing other cooling system work. Backed by trust: Profile Gasket (MPN 11517787692) comes with a 12-month warranty!
