O-Ring between thermostat housing and cylinder head
$4.99
The thermostat housing gasket ensures a proper seal between the thermostat housing and the engine block, preventing coolant leaks and maintaining correct operating temperature.
Over time, exposure to heat, coolant, and pressure causes gaskets to harden, shrink, or crack, which can lead to leaks, overheating, or fluctuating engine temperatures. Anytime the thermostat housing is removed or serviced, the gasket should be replaced to guarantee a leak-free seal.
This replacement gasket from Victor Reinz (VR) is manufactured to OE specifications, providing precise fitment and long-lasting sealing performance.
JC PRONTEZZA supplies OEM-quality Victor Reinz gaskets and cooling system components to restore reliability and protect your engine from overheating.
