I noticed my aftercooler getting hotter then normal the past few months. I was cleaning the car today and noticed that I dont hear the pump with the ign on position anymore. Last I recall, it was setup to come on with the key in the on position and if you open the fill cap you can see the water moving fast.

Its not doing anything now. I believe its tapped into the air pump fuse which I check and is fine.

Anyone else ever have a Comptech aftercooler water pump go bad? If so where to get a replacement. Im sure Comptech will take there sweet old time getting one out to me.

 

And the white wire that goes to the fuse board is that ok?

Is it getting power down at the pump, I'd be checking that down there the with the multi meter first.

 

Any luck with this...I may have the same problem.

 

There was corrosion on the relay terminals. Cleaned them off still no good. Gave the pump a couple taps and its working again. Im going to order another one to be safe.

 

thanks...i remember my battery died once because my water pump never stopped even after i turned off the ignition....by the way, does your aftercooler feel icy cold or warm when everything's working properly?

 

I might have a faulty pump as well, is htere anywhere I can find the wring diagrams for the pump so that there is a way to check the connections

 

i replaced my relay and it came back to life instantly. cause i opened it up and the inside was all nasty looking too

 

where did you buy the relay from?

do you have a part number?

the one I got on mine is a BOSCH 0-332-019-110

but cant find it anywhere




I hope its not the pump that's bad, the wiring is all correct, checked all connections, the relay makes ONE "Tick" noise when the ignition is switched on then not a peep, while the pump remains completely silent

 

have you taken a volt meter to the relay and seen if the pump is getting power?

 

aparently the relay is fine, my coolant pump on the other hand... is toasted
