Product Details

The Melling MWP-502 is a stock replacement mechanical water pump engineered for 1999–2011 GM LS-series 4.8L, 5.3L, and 6.0L V8 engines. Built to OEM specifications, it restores factory cooling system performance with a cast aluminum housing and steel impeller.

Key Features:

  • 100% factory leak-tested to ensure OEM-grade dependability right out of the box
  • Cast aluminum housing for lightweight, corrosion-resistant construction
  • Steel impeller for efficient and durable coolant flow
  • Precision ground, heat-treated bearing shafts matched to water pump rollers for long service life
  • TS16949/ISO9001 premium double-lip bearing seals prevent coolant and vapor intrusion
  • Low-friction, self-lubricating mechanical seals rated for severe operating temperatures
  • OEM-grade grease fill for extended bearing life
  • Hub Height: 6.582 in. (167.20 mm)
  • Does not include thermostat (see MWP-502WT for thermostat-included version)

Assembled and tested at Melling's facility in Jackson, Michigan, the MWP-502 reflects the same OE manufacturing standards Melling applies to its original equipment water pump programs. Each pump is backed by ASE-certified technical support. Sold individually.

Always great service.

Great service

Shipped quickly and accurately

Fast and easy. Price wasn't the cheapest but the product was of fair quality. Everything shipped and arrived in 2 days.

I found the engine mounts I needed but THM did not carry the transmission mounts I needed from the same manufacturer. I had to go directly to the manufacturer website (Innovative) to find them. THM had the best price on the engine mounts though.
