DCCV Brands?

[Rapidtransit]

I'm changing out all the cooiling system plastic components on my 2001 ls V8. Has anyone used the Metrix XR822975 branded DCCV?
As for the aux coolant pump, is this part also recommended to be changed out as well?
If so, is there any aftermarket maker for this part?

BOSCH is the "maker" for them there parts.

The metrix DCCV works I just put one in over the weekend. The only problem I had was one of the valves didn't work once I had it installed a slight tap on the top and it kicked right in didn't want to go back thru the hassle of removing it and shipping it back out. Guess I was just lucky this time round. It the flow off your aux pump is strong I wouldn't replace it. Mines pump but I have to replace it cause it loose it's pumping strength when the coolant gets hot.
