YES ON THE HOSE THEN SWITCH TO THE BUCKET OF A/F.

A/F IS CHEAPER THAN A CRACKED BLOCK OR COOLER:lolhit:

+ 3 (or 4) on this leading to a very bad experience in the spring. (Seen it waaay too many times each spring.) You must find both block drains (on the sides of each block), pull the plugs, then rod out the hole with a piece of wire, a zip tie or something else to dislodge any sediment. Also, did you pull the lower hose on the circulating pump on the front of the motors or just the hoses leading to the exhaust manifolds? Did you drain the power steering cooler?

Hey guys I have been winterizing for many years, but never drained the block. I always run the engine to temp and ran anti-freeze with know problem. This year I did it different ran to temp and drained the block then did the anti-freeze, but I only got three gallons thru before the engine started to heat up it was coming out the exhaust at that point, so I shut it down. Then drained the exhaust manifold. Question is that enough anti-freeze

thanks

Where is this power steering cooler? What is the steering system? I am concerned about all freezing aspects. What does one do about the 'select' exhaust system?

what happens is the thermostat will snap shut before it has a chance to move the antifreeze through the block then you just fill the exhaust manifolds and risers and thats why it takes less antifreeze.. i always use a bilge pump and a tank to winterize all the boats i do..

Should I pull the t-stat and fill extra just to make sure

We usually pull all the drain plugs...run the engine for 10 seconds burping the throttles to get most of the water. Then we run a/f thru muffs on a pump for 3-4 mins, ensuring the t stat is open.

in your case if you can't start the engine...pull all the plugs and fill with a/f. you won't have a problem. On our 6.2's there are 3 but the most important one is the main plug on the bottom in the front. not sure about your setup.

Thanks I think Fix has it right the water was hot coming out off the block, but by the time i had anti-freeze going thru was a few minutes later 5-10. So I guess the T-stat was closing, I`ll pull the T-stat an add a little extra.

if your thermostat isn't open, you get a/f out the exhaust and block is still full of ocean or river water.

also, you need hot water to open a t-stat. drain an engine and start it and the thermo will close. the hot steamy air in the cooling system at that point doesn't open thermostats. if you can't run engine, take off water pump or crossover. drains motor pretty far down. reinstall and fill with straight-not 50-50- real antifreeze-not pink RV crap. remove t-stat housing and fill thru there. then hold hoses that feed exhaust down below bottom of exhausts. and put drives down and leave them there all winter. your shift boots and trim cyls will thank you in the spring...
