Re: Testing secondary coolant pump?

[RCARSELLE@aol.com]

the after run feature on your car is controlled by a sensor at the upper
radiator joint to the block...it is the two wire sensor which has two leads
pointing towards the firewall.....the sender at temperature provides
continuity which allows the pump to run....to test it simply connected the two
wires connecting to the sensor to each other...once you close the ciruit
manually you should hear it buzz and vibrate ..... if not...then find a new
one . . .. remember it is an after run feature to prolong turbo life......so
it is important .  .
