Hi,


A hose that is connected to a t-clutch (pic.1) on the end of tell tale hose did break lose on my engine and water was pumping out from the t-clutch.

The hose leads back and down in a hole next to the oil stick parallel to another black hose (pic.2). It was a easy fix to connect the hose again but my question is if any one can tell me what these two hoses have as function for the cooling system. Are they vital for cooling or just to lead excessive water away and down the rigg to a let out?

Thank you all in advance for help
 
On your diagram the pipe missing connects to the fuel cooler the other 2 ends one end cools the driveshaft bushing the other end goes to pee hole pipe.

Thanks!

Just to clarify I have marked the hoses with numbers for better explanation

#1 - hose to pee hole pipe
#2 - hose to fuel cooler
#3 - hose that came of because of a crack and is now repaired with an extended hose since I had to cut of 0,5 inch to fit again
Is there a risk for loss of preasure or so since the extended part has a wider diameter then the origional hose?
#4 - hose that I believe is for connecting a measure tool of some sort

#3 and 4 is leading down towards the rigg in the hole next to the oil stick.

Thanks again for all help
Staffan
