High flow H/E pump
Monday, July 12, 2010 9:23 AM
What are some good high flow pumps? When I first did my set up I ordered a pump off of eBay . Got everything installed and noticed I couldn't see the water flowing through the fill tank , seemed odd since I've done a few stilled G35 kits and you can clearly see the water flowing . One of my hoses had a slight kink so figured that was it. I finally replaced the kinked hose with a 90 degree hose and now still nothing . I can here the pump running so I know its working . I drained the coolant into a clean pan also so I would know I got as much back as came out its been 2 days and I still haven't been able to get all the fluid back in . Any ideas ?

That could be, but it should still flow either way. I know air bubbles are a huge factor, but with the stillen it sucked the coolant right down pretty quick

Yea it should be still moving, You should take it apart and check the hoses might need to double check the pump....

So torn into the car after work, pump was wired right and working. So i disconnected the hoses and the short one from the fill was flowing fine. The long one that went through the manifold and down through the exchanger was barely flowing anything out. This sounds weird but I blew some air into the hose to back feed it some and coolant started flowing right back out. So im gonna go with a good size air pocket in either the manifold or exchanger. Pumps alot louder now and I can hear the fluid flowing.
