Product Details

Common Cooling System Issues It Can Address

  • Coolant leaks at the thermostat housing
  • Overheating caused by a sticking thermostat
  • Temperature fluctuations from a failing housing assembly
  • Cracked or warped plastic housing surfaces
  • Loss of proper coolant flow control in the engine cooling system

Installation Notes and Tips

Verify the inlet and outlet port dimensions, bolt-hole spacing, and flange thickness before installation. Because the gasket or seal is not included, transfer or replace the sealing components as needed during service. Clean the mating surfaces thoroughly and inspect adjacent cooling system parts for wear, contamination, or coolant residue before reassembly.

Quality Assurance

Four Seasons 85924 is listed as meeting or exceeding OEM requirements for the specified applications. Confirm vehicle fitment for 2003-2006 Lincoln LS and 2003-2005 Ford Thunderbird before ordering.
