Overview
The Crown Automotive 53021051 is a paper thermostat housing gasket for V8 Jeep Grand Cherokee ZJ engines, sold as a direct fit replacement for the 1993–1998 model years.
A thermostat housing gasket seals the joint where the housing meets the engine, which helps keep coolant inside the cooling system. Crown Automotive places this gasket in its cooling parts line for CJ and Grand Cherokee applications.

Gasket care and replacement
A housing gasket is a small part that works hard in the cooling system. Paper gaskets seal by compressing against clean metal, so they perform best when the surfaces are flat and free of old material. Heat cycles can harden the paper over years of use, which is why the gasket is often replaced during a cooling service.
When the Grand Cherokee ZJ V8 cooling system is opened, inspect the thermostat, radiator cap and hoses. Look for dried coolant residue, brittle hose ends and corrosion on the housing. Replacing the gasket along with these parts can save a second drain and refill later.
- Dried coolant around the housing edge
- Hardened or split gasket material
- Rust or pitting on the housing sealing face
