OK so I have a few cooling questions... First what is the best water pump to go with? OEM or are there any aftermarket wps for our cars? (I know there are larger size pullies) Anyone had luck with certain brands vs others in longevity?
2nd I had a feeling either my water pump is busted or there's something clogging my cooling system. When I have the cap off the coolant is not moving period. I mean I should at least be able to see it flowing from one side to the other right?
Ok and how many people have done the cooling system simplifyer trick taking everything down to like just 1 line plus your up/lower? What about running an SRT25 without coolant? (Maybe just buying an oil cooler?) Thanks guys :dblthumb:

The aftermarket pumps will get the job done.

I have done "some" coolant simplicifaction. I blocked off the throttle body lines and have one big line running under the manifold to the block and have a small line running to the turbo around the block. It's alot more simple than before haha.
