Frequently Asked Questions

What does the 53C rating mean?

It switches at that coolant temperature. Match the rating in the title to your original valve before ordering.

How do I test the thermal vacuum valve?

Cold, it should block its vacuum port; warm, it should pass. If warm-up running is poor and the valve does not switch by temperature, it has failed. Check the vacuum hoses too.
