    Strange exhaust behavior during winterizing

    Ok, I'll make sure I drain the liquid from the bottom of the manifolds to make sure. But I have a more basic (maybe stupid) question: Does the coolant come into the manifolds from bottom and goes up to the risers? Or does it come into the riser hoses (that I provided the picture above) and go...

    Strange exhaust behavior during winterizing

    I am not really worried about the mixture, I just buy the -50F AF without mixing water. That easily covers the cold in this area. What I am worried is if the AF has reached everywhere in the engine so that no water left that could be risky.

    Strange exhaust behavior during winterizing

    It is Mercruiser 5.0 MPI. Attached is the larger picture. The two riser hoses merge into a T-fitting under the thermostat, which goes downward, hard to follow where. The T-fitting does not connect the thermostat. My question is, if I fill the risers with AF inside thru the yellow inlet, with a...

    Strange exhaust behavior during winterizing

    Sorry, I meant the riser hoses when I said manifold hoses. The manifold hoses are below the manifolds, so I cannot fill AF there. So the question becomes, if I fill in AF (from funnel, by gravity) in that yellow entry of the riser, will that AF fill the manifold as well, so that it is safe?

    Strange exhaust behavior during winterizing

    No no, just the opposite. The two quick connects hoses go to the single drain at the front. So single drain empties all the water, that's what I did. I am worried about the manifolds, risers and elbows. When I do the quick drain, I believe those don't get drained. How can I drain those?

    Strange exhaust behavior during winterizing

    Ok, I only know how to fill using thermostat housing. How do I fill the manifolds with AF? Remove the manifold hoses and pour AF in?

    Strange exhaust behavior during winterizing

    Each component meaning the left and right plugs on the engine? Yes I remove them and see AF coming both sides The reason I am running thru muffs is to make sure AF goes everywhere in the engine.

    Strange exhaust behavior during winterizing

    Just winterized my engine today 5.0 Mercruiser. Emptied all the fresh water in the engine thru the single point system. Removed the thermostat. Then placed a big jug of antifreeze on swim platform at stern and hosed it to the muffs. Opened the jug faucet and AF starting to leak down on the...

    Thermostat too dirty

    Thank you, after some struggling (install-deinstalled the housing several times), it seems working now on the muffs. I put three layers of gasket to make the plastic sleeve level as the thermostat hole (on the engine block) First I put the direction of the thermostat horizontal (unlike the...

    Thermostat too dirty

    Can somebody help me out there please? Is it ok if I place the thermostat like this?

    Thermostat too dirty

    Allright, thanks folks. I cleaned it, and tried to re-install the thermostat back to its hole. But a very strange problem, that beats me out. The white plastic sleeve protrudes out of the metal block, see picture 1 and 2. Aren't they supposed to be completely flat with the metal block? Even I...

    Thermostat too dirty

    Hello. I removed the thermostat last fall during winterization, and now I wanted to install the new one, but the hole inside it look extremely dirty. Looks like grease and mud, not exactly sure. I didn't notice it previously, because it was full of water (or antifreeze) previously. Attached are...

    Single point drain

    I did it in several stages. Drained the engine by single point quick drain. Then removed the thermostat and filled engine with 3 gallons of AF. Than ran another 2 gallons (possibly half of it leaked) thru the muffs from AF bucket until I saw it on the exhaust. What would be the possible risks...

    Single point drain

    I circulated the antifreeze thru the engine, watched the pink coming from the exhaust, so the engine is all ready for the winter now. But the thing is, I forgot to fog the engine. Should try I run the engine for a short period of time, like less than a minute, while feeding antifreeze thru the...

    Waste tank in 240CS

    Ok, after some experimenting, I figured it out: The holding tank in the picture above is the only one (waste tank). I removed it and cleaned it completely. There is a freshwater tank that provides the water to all the faucets, cold or hot. I put pink AF in it and watched the pink going thru...
