Enginetech Engine Expansion Plug Kits
Enginetech offers engine expansion plug kits for a variety of car, truck, SUV, high performance, and marine applications. Machined from brass or steel, the kits include a variety of sizes to seal whatever ports need to be closed off. The plugs are produced in accordance with factory specs to ensure proper fit and performance. They meet or exceed OE quality standards. Order the kit recommended for your engine. Expansion plugs (or freeze plugs) serve two primary purposes: to block coolant leaks from internal passages, and to protect the engine block from cracking if the coolant inside freezes and expands. The plugs are designed to "pop out" under the pressure of expanding ice, preventing more severe damage, like a cracked block.
