Dart Freeze Plugs

Durable steel freeze plugs from Dart work like expansion plugs. As we all know, water expands when it turns to ice, and if the coolant in your vehicle doesn't have enough antifreeze protection, it can freeze and then crack the engine block. Dart freeze plugs are designed to pop out under such conditions to relieve the pressure on the block, thus protecting it against freeze damage.

Enginetech Engine Expansion Plug Kits

Enginetech offers engine expansion plug kits for a variety of car, truck, SUV, high performance, and marine applications.

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.
