Roush Supercharger coolant pump

[Hawkeye]

The pump for the cooler will not shut off. Normally it runs for a few
minutes after I shut off the engine. Now it runs continuously. I found this out after the battery went dead. The dealer gave me a new battery under warranty - 2013 with 35,000 miles - went back to the dealer the next day cause I could hear the pump running after being parked for 5 hours.

He confirmed and traced it to a bad relay. They had the truck today and put in a new realay. I picked it up and brought it home. Yep, the pump is still running so I disconnected the battery and will head back to the dealer tomorrow.

Any thoughts?

Thanks,

Brian

Hey Brian. It may be the relay that powers the circuit which tells the water pump relay to turn on. Call me for a few things to check. Please make sure to have a test light ready. I will be traveling tomorrow so if I don't answer, please leave a message. 858-437-3167

Thanks. It is back to the dealer first thing. I'll see how I make out there and will post the results, before bothering you.
