1995 Chevy Camaro LT1 Water Pumps - Performance Parts

Meziere Enterprises in Escondido, California, is one company that has electric water pumps down to an art. Not only has it engineered its products to perform beyond efficient, it has taken the time to build the products with a cool appearance. Not that appearance matters in terms of performance, but it's always rad to have a nice-looking piece resting under your hood instead of some Mickey Mouse getup. Over the years, Meziere has enhanced its product line to cover the better part of the Chevrolet engine realm. From small-blocks to big-blocks, LT1s to LS1s, and even the new LS2s, they carry a full lineup. In our case, we only needed one application-an LT1 pump.

The Meziere electric pumps for the LT1 engine are built with every bit of quality and ingenuity as the rest of its lineup. The pumps are manufactured from a fully CNC-machined one-piece main body. Inside the machined housing, Meziere stuffs a direct-drive electric engine that only draws 8 amps. The pump is capable of flowing 42 gpm of water, and its heavy-duty version can flow 50 gpm. In case you're worried about touching that prima donna known as the Optispark, Meziere utilizes an integral bearing and seal housing design that is Optispark safe, and by that we mean you won't have to worry about any leakage dripping down onto the Optispark and causing a major malfunction.

With the shroud out of the picture, it freed up some space. Next, the old pump was yanked, and we began cleaning off the old gasket with a razor blade. You want to make sure to remove as much leftover gasket as possible to ensure a tight fit for reinstallation.

With the pump pulled out, the mechanical internals of the pump would need to be yanked, and the rear of the housing would need to be plugged. You can see the plug here, which basically looks like the end cap on an ironing board or chair, resting in place.

Once the area was cleaned off, it was time to install the new Meziere 50-gpm pump. However, we hit a bit of a snag. When we went to call around for a water pump gasket replacement from the local parts stores, we couldn't find any! We had to improvise and used a Permatex Hi-Temp Silicone Gasket Maker. We would recommend a new gasket, but this will work just as well. By putting a very thin layer of the gasket maker and evenly spreading it on the pump, the silicone will act as a makeshift gasket.

The entire black anodized unit weighs just 3 1/2 pounds, and comes with a two-year unlimited-mileage warranty. The life expectancy of these Meziere pumps is rated at a street-ready, 2,400-plus hours. Unfortunately, we're not math experts, but with our simple calculations averaging about 15 mph multiplied by 2,400 hours equals about 36,000 miles; we don't think you'll have to worry about wearing one out any time soon. But if for some reason you do, you have a few options.

One is to order a new unit; second is to send the pump back, and Meziere can repair it. Depending on what went wrong, the price range for a repair runs between $50-$100, and comes with a one-year warranty.

As far as installation goes, for the most part it's like changing a new water pump. Once the factory pump is pulled from the engine, it is gutted. The cam-driven components in the pump need to be removed. The back hole in the housing is then plugged. Once that is done, it's simply a matter of bolting the Meziere pump to the housing and reinstalling the entire unit. Once installed, the pump needs to be tapped into an ignition wire to ensure the pump turns on at start-up. It's a pretty simple install, and should take just half a day to complete. But in the end, it does yield some promising results.

Once the silicone was spread, it was time to install the black anodized Meziere water pump. Because we used the silicone gasket maker, we installed the pump by finger-tightening all the bolts. We then set the gasket maker for about 30-45 minutes before we tightened down the bolts.

The pump comes with a built-in plug. To make the pump turn on, it needs to be tapped into an ignition wire. Once an ignition wire is found, tap into it and ground the pump.
