You are confused. ITs taking water that comes from the water pump, on its way to the heater core and its pumping it through my coolant loop and back - you can't see the return line but it goes to the de gas bottle. The inlet tube is pointing at the engine, the out let is pointing to the rear.
Got ya, I was getting it mixed up with my setup, and crossed in my head which way the pump was pushing. So if your vegi return is in between the cold heater core line and degas bottle, the path of least resistance is to the degas bottle, and not backwards through heater core to the hot side. Probably if anything, you may have lost a little flow through your heater core, but same for me too, Vegi getting heated is more important than me getting heat in the cabin. :thumb:

Well this little pump did not prove to be a good one. The heat from the coolant warped the inlet and outlet pipes and they started colapsing and leaking...I will contact the people i bought it from and hopefully they will have some insight as to why a "coolant" pump didnt hold up to the hot coolant.
Maybe i jusat got a bad one?

Ehh I cant say that one would be bad, its probably that all those pumps cant handle the hot side, if you can get another one for free, put it on the cold side.

Its made to go on the hot side of a mercedes to the heater core so i can't see how this application is any different? Do mercedes run cooler? :dunno:

the couple times I have seen this talked about in other forums they usually say they install them after the loop to pull the coolant rather before the loop pushing. If you call in a warranty on this pump, i would not tell them that you installed it on a truck. they will probably tell you where to go :)

I cut the plug off to wire it and i will have to explain that... i likely won't get my money back. The pump isn't ruined, if i have to i will try to round out the inllet/outlets with some heat and reinstall it on the cool side and see what happens. The inlets are just a little out of round.

The pump in a Mercedes is in the return line to the water pump so temps would not be any greater than say 140 - 150.:twocents:

Clay,
So how did you end up wiring it? where did you cut it in? Looks like I may be doing the same thing for my 02 ex.
thanks

Wire it to a 12v source that is hot when the ignition is on and i put a switch inline so i can turn it off in the summer time.
I grounded it under the hood right next to the location of the pump.
This pump has some odd looking terminals on it, i happened to have some crimp type connectors in my box of wiring stuff that fit those terminals nicely so once you get the pump, take it to autozone and browse there wiring section for those terminal conectors.

Now the real trick would be to find this baby in 110v, and plumb it in front of one of these and put it on a timer. Wanna switch to veg faster?

Our electric is still much cheaper than the equivalent in diesel - less than $.05 KWH. Run both for an hour in the morning before you take off for a few cents...

Well I was thinking of putting one of these on my 7.3 cause im adding a coolant filter and I didnt want the stock pump to have to much resistance. Well the link to the one Clay had... well let just say it went up a few pennies~~~~~~~ $176.85~~~~~~~
Any one else got a cheaper source of these?

My coolant filter setup is just a bypass and only takes a portion of the coolant flow. Is yours inline? If not, you might run the risk of out-flowing your coolant system for no reason. Or you could just try changing your filter.

Any time you add more length that a pump has to push or pull your adding resistance bypass or not. The pump wont be for the filter but my V3. Guess i didnt clarify that.
