First time winterizing a 2000 volvo penta 5.0 gi PEFS

[funshipbryan]

I have spent the last 3 weeks trying to get as much information on winterizing a volvo penta 5.0 gi PEFS engine as I can. I have the small Owner's Manual that came with the boat and I also bought the Clymer Volvo Penta Stern Drive Shop Manual (1994-2000). Being that I am new to everything boating, this has been a confusing endevour. What I have done so far is to removed the two brass bolts on the bottoms of the engine block (stern and port) and also have removed the two brass bolts at the back of both manifolds. I used a small stiff wire to keep poking at these opening while the water was draining to make sure they didnt get plugged up. I then unattached the two larger hoses going into the raw water impeller and allowed any water to drain out. One thing that is in the small owners manual booklet that I have search and search for on the net is what the heck is the Vapor Separator Tank.... there is no picture of it or location of it in the manual, neither the shop manual nor the small manual that says to drain the hose. The exact wording in the small manual is : Remove the water hose clamps and water hoses from the vapor separator tank. I had called a volvo penta dealer and was told it is located between the two fuel pumps and it is a small canister and to just remove the hose and blow in it. I did find a canister looking device between the two fuel pumps that has a metal label that has Carter on it and some numbers, I assume this is it.... there is a small diameter hose going into the top, I removed the clamps and blew in it, nothing felt like it moved, just like blowing into a hose that has no circulation. I have put back in all the bolts, reconnected the hoses, I guess my main question is..... have I done everything I need to do to prevent any freezing this winter. I live in western maryland where it gets into the single digits so I do not want to mess up and crack my engine. Any help or advice would be very much appreciated. Oh, also in the shop manual it says to drain the sx drive, but the picture shows some draining screw on the port side of the drive, which of course there is no screw where the picture shows..... do I need to do anything to the SX drive to winterize that?? I am hoping I can get this down so next year it will be a snap.

Go to the link below and spend some time looking around. Bet you find your answers and more inside.
After buying a Clymers manual, no wonder you're confused.

Hi Don,

Thank you for replying. I am looking through the different links and will read some of them tomorrow (almost midnight right now). I did a lot of the things they talk about in the one article, as far as filling up the tank, added marine fuel stabilizer, changed the oil and filter, changed the gear lube.... I didnt fog the engine because the engine is an EFI engine and I have read different opinions on wheter to do that or now, still out on that one. I was hoping to find more specifics on this particular engine, as far as exact location of where I need to drain and more information on the SX drive. I was not planning on pulling the drive, I am not a very strong person and my wife is the only other person that I could look to for help and I can't see her and I pulling the drive out of the boat, so I was hoping that I could just make sure it is drained or whatever to be kept outside under the carport with the fitted tarp I just bought. You said the Clymer manual is not very good, is there a better one with more details that I could purchase? I am open to learning as much as possible but again was hoping for more specific information (pictures would be nice) of this exact engine.

Bryan,

You need to make sure that you remove the hose at the engine circulation pump. Find the large hose on the thermostat housing and follow it to the circulation pump. Remove the hose and drain. This hose can hold a lot of water and removing it will also get the water out of the pump.

I believe this engine uses throttle body injection (TBI). It's still fuel injected; however, the injectors spay fuel into the throttle body not directly into the cylinders. You can fog this engine using the standard method of spraying fogging oil into throttle body until you get some good white smoke going. Using an external tank with a 2 cycle oil mixture (50:1) and stabilizer connected to the fuel pump is also a simple method of fogging.

Hi Kblaster, thank you for responding to my post. Forgive me for not having a lot of knowledge at this point, I am trying to get educated as much as I can. But looking at a picture of my engine in the manual it doesn't show anything labeled thermostat nor anything labeled circulation pump. On the front view picture it shows a picture of the Raw Water Pump and Impeller and right above that is a circle with 5 bolts, kinda looks like the 5 on the side of a die but circular instead of a cube. It does have a large hose coming into it. Is this the circulation pump? Also on top of the engine where this hose comes from is a metal piece with several hoses attached to it, is this the thermostat? Also, is there a trick to getting hoses off, I actually tried to remove these hoses and they would not budge.

Hey Bryan,

My name is spelled the same way also!

I'm going thru the same deal, and have a thread going about my winterization. I had some issues with stuck hoses as well. I ended up using a dull flat head screwdriver to help pry the hoses loose. Be careful as to not cut thru the hose with screwdriver! I also build an outdrive stand (again see my thread with pics) It made it very easy for one person to remove the drive. I also would advise a remote tank for fogging the EFI/MPI engine. Very easy to do! I removed over 5 gallons of water from the block an hoses on my 7.4. That's a lot of water ! Good luck brutha!

My circulation pump is below the center pulley in this picture, at the very bottom center of the engine.

Yes that is the ciculation pump. You need to get that hose off. I bought a hose pick from Amazon.com to help get the hoses off. Kinda-of a cool little tool.

Also on top of the engine where this hose comes from is a metal piece with several hoses attached to it, is this the thermostat?

That is called the thermostat housing. If you removed it you would find the thermostate inside. Funny how that works.

See if this drawing of the cooling system helps any.

Re: First time winterizing a 2000 volvo penta 5.0 gi PEFS

Thanks Don for the drawing. So far I have drained from the two hoses the lead into the raw water pump, have removed the hose going into the circulation pump, I have removed the 2 brass bolts at the bottom of engine block (port and stern) and also the 2 brass bolts at the back of each manifold. Is there anything where else that I need to drain from or any additional hoses that I have to remove? The two area's that I am not sure about is the one that runs into the bottom of the fuel cell and the one that runs back to the power steering pump cooler, I did drain from the raw water pump side, but I didn't remove it on the power steering pump cooler side. Any insight would be very much appreciated.... if I am good to go at this point, that would be excellent but if I need to get back in there I want to make sure I do it quick because the temps are falling at night.

As far as the hose that runs to the fuel cell, I simply remove it from the thermostat housing and blow through it until all the water is removed. The water goes into the exhaust manifold and out through the drain plug. If you've already reinstalled the drain plug, you could remove the other end of the hose from the manifold and drain. As far as the hose from the power steering cooler to the raw water pump, I usually fill it with antifreeze at the pump until it comes out the drive. That way you know antifreeze has pushed through the power steering cooler and out the drive. Probably not absolutely necessary, but I sleep good at night.

Hi Kblaster,

Thank you for the reply. I do have a question, when you say you fill at the pump side until it comes out the drive..... forgive me for my lack of knowledge but what exactly does that mean.. comes out the drive and where would I be looking. Also, do you backfill with antifreeze from any other hoses? Thanks again for your replies, I really do appreciate the help.

Re: First time winterizing a 2000 volvo penta 5.0 gi PEFS

Ohh the drive, daa on my part, as in the outdrive... didn't realize that the two terms were the same until I started googling the term. So looking at the picture that Don had sent before about the water circulation of the engine, I assume that the raw water pump pulls in water from the drive and that connection from the drive to the raw water cooler passes through the Power Steering Pump Cooler. I will have to stick my head back under the engine and follow that hose so I can learn one more part of this engine. So I will pull that hose and backfill with antifreeze, my wife is actually at wallyworld now picking some up for me. Do you backfill any of the other hoses?

Re: First time winterizing a 2000 volvo penta 5.0 gi PEFS

I don't intend to start another battle of the antifreeze and non-antifreeze proponents, but I like to put some in the block through large hose that leads to the circulation pump. I remove the hose from the thermostat housing and pour some in. I only used a gallon or so this year ? not really sure how much I?m supposed to use. I also like to remove the exhaust manifold hoses (2) from the thermostat housing and pour some in the manifolds. Like I said before antifreeze is not necessary, but it makes me a little more comfortable. Even though I use the non-toxic version, I still remove it before the first trip of the season.

Thanks Kblaster, I am going to get under the tarp tomorrow and do some more winterizing. I really appreciate all the insight and help with this. I want to make sure I do this right so I don't have a big expense in the spring fixing some freezing issue.
