Install a new o-ring for a proper seal. 36×3.15
$1.00
The coolant outlet O-ring ensures a proper seal between the coolant outlet and mating components, preventing coolant leaks and maintaining correct operating temperatures.
Over time, exposure to heat, pressure, and coolant chemicals can cause O-rings to harden, flatten, or crack—leading to leaks that compromise cooling system performance. Each time the outlet or coolant piping is removed, this O-ring should be replaced to guarantee a leak-free installation.
This replacement is manufactured to OEM specifications, ensuring precision fit and long-lasting sealing reliability.
JC PRONTEZZA supplies OEM-quality O-rings and sealing components to keep your cooling system properly sealed and your engine protected.
