    Chevy - LT1

    Over 10 Rear Wheel HP Gains! This LT1 water pump has proven Mezieres reliability with customers logging 50,000 to 60,000 miles on their daily drivers. For many, the economical price and longevity make it a logical choice over the factory replacement. Along with the horsepower savings, the relocated seal drain eliminates the possibility of a pump leak causing optispark failure. The need for the heavy and expensive factory timing chain is also eliminated. Some Camaro/Firebird (F-bodies) may require trimming of the fan shroud. No inlet required.

  • Fits GM LT1/LT4 engines as an insert into the factory pump housing
  • Suitable for street or drag strip use - 2500+ hour life expectancy
  • Show quality black finish
  • Standard motor provides 43 gallons per minute free flow rating
  • Light weight. Complete unit weighs only 3.5 pounds!

    Keep Your Car Cool... Perfect for 12V or 16V Electrical System

    Meziere's 100 Series Electric Water Pump is lightweight and flows 35+ gallons per minute. They are ideal for mild street and Sportsman drag cars. The pump housing, motor cap, and impeller are CNC-machined from 6061-T6 billet aluminum for superior corrosion resistance. The stainless steel impeller shaft runs through a 1-piece carbon-ceramic seal that isolates the epoxy-coated motor from coolant for years of reliable service. The motor has a radio frequency suppression circuit in the motor brush card to reduce ignition "RF" interference. These 100 Series pumps are available with two motor option, standard duty and heavy duty. The HD (heavy duty) motors provide more power and RPM, increasing flow and pressure over the standard duty motors. HD motors are recommended for street cars and other continuous duty applications (where high flow model pumps are not available). Most pumps are machined with a 1" NPT port(s) to direct water into the pump using one of the inlet adapters that you choose to best suit your needs. Inlet adapters are available in slip-on rubber hose style to AN sizes, inlet fittings are sold separately and not included with pump. Most pumps and fittings are chrome, polished, or anodized. Longer inlets, extensions, and angle adapters also available.

    Meziere pumps are American made with pride and quality far superior to any other performance aftermarket company. Don't be misled by the inflated flow numbers and outlandish claims of others. Meziere says what they mean and means what they say. The 2 year, unlimited mileage guarantee and full satisfaction money back guarantee should convince you that buying Meziere is buying value!

  • WP118 - Meziere 100 Series Electric Water Pumps is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from The part was a direct replacement for my original Great quality pump. Easy to install the replacement as most of the work is removing the internals of the oem pump. The only complaint I have is the pump does not include the required O-ring. I called Meziere and they gave me the GM part number but said I could reuse my stock O-ring. These cars are 20 years old now and you really need to replace the O-ring for a leak free seal. I had to special order from my local GM dealer and wait two additional days to install. Meziere should include the O-ring with the pump along with some water pump gaskets. Otherwise, you will be making another trip to the dealer or placing another order online. The lack of gaskets is the only reason for the 4 star rating instead of 5.
