Detailed Product Overview

Calorstat TH6513.87J is engineered for vehicles that require an 87°C thermostat specification, including Mercedes-Benz E500, S500, SL500, ML500, and Chrysler Crossfire applications. The aluminum housing and gasket-style seal support a secure fit at the thermostat housing interface, while the jiggle pin weep hole helps purge trapped air during coolant service. This part cross-references Gates 33930 for the same application.

Use TH6513.87J when replacing a thermostat that is stuck open, stuck closed, or no longer regulating coolant temperature correctly. The 188°F opening point matches many OE-recommended 87°C cooling system setups across Mercedes-Benz V8 and AMG models.

What This Thermostat Helps Address

• Engine running too cool from a thermostat stuck open
• Overheating caused by a thermostat stuck closed
• Temperature fluctuation during warm-up and driving
• Coolant seepage at the thermostat housing seal surface
• Air pockets in the cooling system after service

Installation Notes and Fitment

Install with the sealing surfaces clean and free of old gasket material. Verify the housing orientation, bolt-hole alignment, and coolant specification before reassembly. Bleed the cooling system carefully after installation to remove trapped air.
