【Function】The engine oil priming tool builds a connection with the shaft of the oil pump through the hole of the distributor and inserts it into the oil pump. Priming the engine helps in filling up internal oil passages.This way, when you start the engine, it's already immersed in oil. And the engine oil can lubricate and cool down the engine's moving parts.
【Superior Design】The thick shaft design with a triangle-shaped end helps prevent slippage. This unit works well with a 1/2-inch or 3/8-inch chuck hand drill, and it features a special billet aluminum sleeve that helps pressurize the valve train to pump up the oil.
【How to Use】Slip the primer rod into the hole of the distributor shaft, which is located within the manifold, then you need to get the oil into the valve train, rockers, and camshaft. While you prime the engine, use your other hand to rotate the crankshaft.
