fischer panda leak

[ttles714]

My PMS 4200 is leaking antifreeze.. I can see it coming from the bottom of the unit but can't locate the leak ... I know I am grasping at straws here but maybe someone can help out... Another thing I feel stupid but i can't find the oil filter !!! this generator is new to me so any help would be appreciated.
boat is 2007 Marlin

thanks

There are several spots that the antifreeze could be coming from, I think there is a schematic of the internal cooling system in the install manual but the generator does not have a filter. It has a screen the only needs cleaning occasionally.

I think after further inspection that the leak is somehow related to 2 hoses that go into the back left side of the unit. There are 2 hoses that seam to come off a "vent valve" "u" shaped pipe. they go thru the case. when i move them around it seams i can cause more leakage. But if i am reading the diagram correctly those two hoses are RAW water. Can you tell me how to access the fresh water (coolant) pump or even where it is ??? i would imagine the generator would have to come out as i really can't even see whats going on. does anyone have any information on removing this unit ?? if you have any ideas at all i would be glad to hear them.

Added : I see in the diagram where the electric water pump is mounted up against the heat exchanger , but i have nothing mounted there !!

So I found my leak. the pressed in hose connection at the "cooling water block" was no longer pressed in ... kind of a stupid design or so it seams.. i wonder why they did not use a threaded hose barb. I gave it a repair shot with JB Weld .. we will see what happens.
