    Recommend using a new pickup tube assembly when installing oil pump. Pump not recommended for high mileage engines with low oil pressure. Instead use M295HV, high volume oil pump; the additional oil volume will increase oil pressure.

The Chevy Trailblazer EXT oil pump provides lubrication and cooling to all of the engineÆs moving parts. When the oil pressure warning light comes on, it indicates low oil pressure. Unattended, this leads to the engine seizing causing expensive repairs or even entire engine replacement. Ticking or clanking noises from the valves or lifters is another sign of low oil pressure. While oil pump replacement is something best left to certified technicians, purchasing Trailblazer EXT oil pumps is best done at AutoZone, where you receive Free Shipping on orders of $75 or more and Same Day Store Pickup (in most cases) when you shop online.
