These rings create a tight, leak – proof seal where different parts of the cooling system connect – usually around hoses and pipes. Think of it like the gasket in your engine, but for coolant instead of oil. It essentially stops fluid from escaping where it shouldn’t. They’re often found where a hose clamps onto a metal pipe, or where two sections of pipe join together. It’s part of the cooling system, which, as you know, prevents your engine from overheating. The seal ring keeps the coolant where it needs to be, circulating through the engine to pull away heat. Without it doing its job, you could lose coolant, and that's a big problem. It's a small part, but it plays a crucial role in keeping everything running at the right temperature. Losing coolant because of a bad seal can cause your engine to overheat quickly, and that can lead to serious, expensive damage. You’ll notice if one of these is failing because you’ll probably see coolant leaking, maybe a puddle under the car, or even steam coming from the engine bay. It’s a relatively inexpensive part to replace, and doing it proactively is way cheaper than dealing with an overheated engine. Places like Fixparts Online often have these in stock, and they’re pretty straightforward to install if you're comfortable doing a little DIY work. Ignoring a leak, even a small one, can really bite you in the long run. Smart investment: Seal Ring (MPN N90544501) comes with a 12-month warranty!
