VP 2002 Heat Exchanger

[Saber 30]

So, HE arrived and no extra fees woo hoo. Has any one installed one of these units on a VP 2000? What type of hose used to plumb? How did you modify support to attach the exchanger?

Hey, has anyone here installed a Mr. Cool heat exchanger on a VP 2000 series. I am in the process now but would love to hear from anyone with advice, tip, tricks or pics. Thanks.

Your biggest obstacle is connecting the volvo "push fit" pipes to new HX hose nipples.
There was a post on here a while back from a member who got tired of the leaking VP system & replaced all the copper pipes with hose & short copper nipples.
I will try to find the post. /Len

So I was able to get the VP 2002B running, I have it set up in my garage. I took the wiring harness and gauges out of the boat and did my best to hook them all up but things are not working great yet.

My biggest problem I am having with the engine is it is running hot on higher rooms. I just checked the installation of the cooling system in my manual and it seems I should have blocked the hole at the rear of the engine just below the exhaust elbow. I ran a hose to this as this is the way it was when in the boat...I think it ran to my HW tank. I don't have the hw tank installed in my set up.
My question I guess is does it make more sense that the coolant will circulate better with this hole plugged and the hose that ran to it plugged?

I don't believe that outlet at rear & the short pipe from it to the elbow are used on FW cooled 2002. They are blocked off.
You need the FW cooled thermostat too. Pls read thru this description:
