Fitting may be too big

When I installed it in my thermostat housing it only turned in about 2 threads worth and left a lot of threading exposed. As long as it's sealed I don't care but it doesn't seem as secure as the old oem part. Maybe chasing the threads will help.

1 Answered question

Where does this part mounts on the water pump???

Asked by Miguel from San Lorenzo, PR on

Hi Miguel! This water pump tube connects the water pump to the heater core. The threaded end goes in to the water pump, and the other end connects to a flexible hose with a hose clamp that goes to the heater core in the firewall.
