Hi. I'm preparing to winterize my boat that has a VP 4.3 GXi-JF engine from 2008. Since the pictures of the manual that came with the boat and actual engine look a bit different I'm hoping to get some help from discussion here.
To the raw water side I will just hook up a canister of AF on the engine flush port which will run through the impeller housing and pushed through the heat exchanger and manifolds and exhaust. Afterwards probably also drain the impeller tubes and manifolds. Probably also tape the drive intake holes so it wont suck air instead of AF from the flush port. I understand that the power steering cooler will drain itself when the impeller tubes are disconnected since the part is under an angle in the back of the engine, correct?
Howevever, since the boat is new to me I also want to drain the closed cooling part. Anotherwords, since I don't know the coolant's properties, I will treat the coolant as if it were water. So I need to drain it and replace with proper coolant. The manual only says "Make sure the coolants freeze point is adequate for expected temperatures", nothing about how to perform the procedure.
So I was thinking to drain the engine block from both sides.
On my case, there is a defroster hooked up to the engine so I'll just take the hose of from engine drain and thats that.
Then, I understand I also need to drain the fuel pump from coolant, so probably just unhook the lower end of this tube, correct? One tube also runs from the fuel pump into the exhaust manifold, should I also disconnect that one??
Since the heat exchanger is lower than the engine block drains it will still hold the old coolant, what would be the hoses to disconnect to get everything out?
Every bit of info is appreciated, up here some have already reported first snow
