Product Details

The Cometic C5538-047 is a precision-engineered thermostat housing gasket designed specifically for Chevrolet Generation 1 Small Block V8 engines. This gasket provides a reliable seal between the thermostat housing and the intake manifold or block, preventing coolant leaks and ensuring proper engine temperature regulation.

Key Features:

  • Constructed from durable .047" (1.2mm) thick fiber material for superior sealing and longevity
  • Custom-designed for precise fitment on Gen-1 Chevy Small Block V8 engines (265, 283, 302, 327, 350, 400 cubic inch)
  • High-quality fiber composite resists coolant, heat, and pressure cycling
  • Manufactured by Cometic Gasket using advanced die-cutting technology for consistent quality
  • Direct replacement for OEM thermostat gaskets

This gasket is an essential component during thermostat replacement or cooling system service. The fiber construction provides excellent conformability to sealing surfaces while maintaining structural integrity under engine operating temperatures. Ideal for both restoration projects and routine maintenance on classic Chevrolet small block engines.

great so far , happy to have found what I was looking for

Great company..Great communication..Fast shipping. A+++++++++++++++.<br>Will do business again.

It was easy.

My ARB 50qt fridge/freezer arrived quickly and it was way cheaper than anywhere else. I was a little leery only because of that. However, I received the fridge and saved about $65 over even Amazon. No problems.

Pricing was good and customer service quick to respond.
