In most engine cooling system applications, coolant travels through the block, up in to the cylinder head(s), and out of the engine at the thermostat housing. From there, it passes to the radiator to be cooled.

Ideally the temperature probe should be plumbed into the system where the coolant is hottest – generally, the thermostat housing, in the coolant passages adjacent to it, or in the water jacket of the cylinder head(s).

You can use a SAAS brass adaptor to tap into an available coolant jacket port, or in the absence of any of these alternatives, splice into your top radiator hose using a SAAS Water Temp Adaptor fitting.
