My V3 switches on much faster now when its cold out and before this pump install, i was loosing so much heat, If i sat idle for too long the V3 would turn off indicating low coolant flow to the module...not anymore.
aboput 182 out of th thermstat housing but the lines i don't know. I was just feeling them with my hand and i could tell the return line fro mthe tank was about 100*....now i can't hold my hand on it for any length of time.What are your coolant temps running in this cool weather???
yep.........He was saying that the 6.0 is plumbed different than the 7.3s OBS and superduty. So yes I agree on your truck and mine the hotest coolant is out of the block line then return to the pump. On the 6.0 the heater core return goes to the degas bottle and not the pump. So whether it may not be as hot or as much flow as us, alll he has for a heat source is the line off the water pump.
These Mercedes pumps are solid. My father had to add one to his 82 Mercedes grease pig for the same reason, Mercedes flow very little coolant at idle so one of these pumps is used for the heater hose application specifically to be able to draw heat into the car at idle.
On your 7.3 you should not need one. It is "aiding" the pumping cylce...not pulling or pumping per say, but speeding the process.I have been hearing good things about this little pump. I am going to get one too.
is it pumping coolant through the system or pulling it through the system?
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.by looking at your picture its pulling from the vegi cold side, do you think there is an issue with the pump pushing coolant backwards through the heater core at the tee to the hot 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: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.
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 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
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.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.
Not sure but go here and sign up and you'll find lotsa info and pics.Clay, do you have the old pictures still?? I can't see them anymore. I'm trying to plan out my system, and they would help. There aren't a lot of pictures online of 6.0 conversions.
