Keep coolant sealed at the thermostat and stop seepage around the housing with the Motorad Engine Coolant Thermostat Seal MG-187EA. It's a direct-fit replacement for the listed applications — the 1994-1998 Dodge Ram 2500 and the 1994-1998 Dodge Ram 3500 — dropping into the outer position at the thermostat to seal the joint between the thermostat and its housing against coolant loss.

  • Mechanical job: forms a stationary seal at the thermostat-to-housing joint so engine coolant stays contained within the cooling circuit.
  • Position: installs in the outer location as cataloged for this part.
  • Direct-fit application: replacement for the Dodge Ram 2500 and 3500 applications listed below.
  • Signs this seal may need replacing: coolant weeping, drips, or a damp film around the thermostat housing, and coolant loss with no other visible source.

If a hardened or damaged thermostat seal is the source of a coolant leak at the housing, this replaces it. Inspect the mating surfaces and refill and bleed the cooling system after installation.
