Other than it looks like something the Germans came up with, but the flows in some places are mysterious, I don't know what that cluster of pipes behind the firewall could possibly be doing ??

Did I win the interwebs today ??

 

The is a serious question that I cannot wrap my head around as why I am asking.... Starting a project here shortly

The cluster of pipes you asked are for the intercooler-as I put this on the Pro xp Forum..

I am trying to figure out the correct flow path for a project but find it hard to believe that the flow out of the oil cooler is cold flow.. In yes out No/
I see there is a line missing out of the water pump to the block.

I see a mixture of Hot engine coolant and cold going into the water pump...

Maybe I should make this pic larger...

 

 

Didn't really help, I even opened it in another tab... I'm as baffled as you are now that I know what you're trying to do. I think it'd be more useful if they would provide a couple different views, as there's not a lot of usable information in that "schematic" and what information there is, as you pointed out, doesn't make sense, at least not to me. Perhaps it's just one of those situations where you plumb what you can see, and the rest will work itself out when you look at the smaller job so to speak..

 

Thats correct, thats the bypass system and where the thermostat is. Once the coolant gets high enough, the bypass closes and no hot water comes in the bottom of the pump anymore.

 

But why is there cool water coming out of the Oil cooler?
There is a line out of the water pump ( upper that must be hidden in the pic) it's on the machine- where it comes out of the water pump on the upper most top and goes into the block it appears- cant follow it all the way up due to the heat shields

 

The picture sucks, thats for sure, but it is correct.

 

@WISledder Sent you a message

 

 

The Intercooler and Engine are (2) separate cooling systems, the only thing they share in common is the reservoir. There is an electric pump for the intercooler, PITA to get to.

 

I think I see what wrong here, where I circled the picture is the inlet and outlet for the Oil cooler, the flow is correct, but the color is wrong, this is hose 5 below.

 

See how messy this simple flow gets. But I see what your drawings represent. Appreciate you taking the time

Yes... the in to the oil cooler is somewhat cold and is the top small inboard post out of the water pump- The hot out of the oil cooler goes into the outer most small port on the outside water pump, and gets mixed back into the system to the block

So with the thermostat closed -water circulates counter clockwise through the motor & bypass hose till it reaches lets say 180* -thermostat opens and hot water is routed back to the Rad for cooling Via top hose off the thermostat housing...So what happens in the by pass hose at this time as it is still expelling hot water
in-conjunction with the hose out of the thermostat to the RAD ? I didn't see anywhere the bypass valve or how it closed ( I think that is key)

The by pass hose is MAYBE sharing hot water flow into the cold coming in from the water pump, from the Rad after its it has cooled..
I think that's why we always see the temp we see cause of this sharing of fluid?

Big Question and the reason for all this is ..
So where is the hottest line to tie into pre thermostat?
If post thermostat It will be cooled off as the thermostat opens, The line off the oil cooler may be to small of a volume, and when the flow chart show's cold out, it really started to wind my mind.

Nothing I can see it the hottest line except for the Oil Cooler out OR....... quite POSSIBLY, the Hot discharge line off the Charge air cooler? I don't think its as hot maybe as the oil cooler line

 

See how messy this simple flow gets.
Yes the in to cooler is cold and is the top small post out of the water pump- The hot out of the oil cooler goes into the outer most small port on the water pump.

So where is the hottest line to tie into for heat pre thermostat?

There isnt a good place that I can see. The thermostat housing is built on the back of the engine block, ideally there is where it should go but there is no access, Polaris already has their sensor there . Next best spot would be the return line post thermostat (pruple cirlce)

 

Yeah it just cools off to fast from the thermostat being closed using a temp gun.
I will try to shoot temps off the Line out of the charge air cooler and see who is the HOTTEST Tamale .. but I bet the discharge from the Oil cooler is the one...
