About Dorman

Dorman Products is based in Colmar, Pennsylvania. Mechanics have trusted the Dorman name for more than 100 years. The company built its business on parts you used to get only from the dealer or a salvage yard, like oil coolers, radiator fan assemblies, and intake and exhaust manifolds. Today Dorman markets about 144,000 distinct parts, many of them designed and engineered in-house, for passenger cars and light-, medium- and heavy-duty trucks. Its OE FIX line goes a step further. Dorman looks at what made the factory part fail, then redesigns it so the repair holds up.

What we carry

Our Dorman shelf is mostly the cooling-system and belt-drive wear parts that keep a daily-driver or work truck on the road.

  • Idler, A/C bypass and power-steering pump pulleys, plus serpentine belt tensioners
  • Clutch fan blades, fan clutches and fan shrouds
  • Coolant recovery tanks, thermostat housings and heater hose assemblies
  • Harmonic balancers, rear main seal covers and valve-cover and rocker-box gasket sets
  • Oil pans, oil coolers and HPOP hoses
  • Cabin air filters and air intake hoses
