I had a question on the drain plug location. I have the GT 40 v 8 95 SN. Are they the T bolts on the side with plumber type tape on the threads. It appears there are 1 on the driver side of the motor and 2 on the other.
Also hoses, which one need to be released to get all the water out of the engine? Lastly, anti freeze goes in the hose once all the plugs and hoses are back in right? How much,.... and will any RV pink type work? |

The "T Bolts" will let the water out you will also nee to take the pluges out of the exh. risers there will be pipe plugs in the back of them there is a plug on the bottem of the "U" pipe on the front of the engine you will need 2 jugs of rv antifreeze dont forgit to fog the engine
Good luck ------------- Dont Hate "ACCELERATE!" |

one misconception on the block drain plugs is, you will drain one side and then go to drain the other side and at times nothing will come out and then it is assumed the block is drained, alot of times you will get corrosion near the drains and it will block any water from coming out. So it is very important to probe the drain and clear the blockage to let the water out. ------------- "the things you own will start to own you" |

Yes, I agree, probe first and then let it drain. It'st sort of like smell first and then go after it!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Great, got all plugs but the 2 on either side of manifold risers, here is a pic. I see a plug that take a wrench nut no obvious drains. Am I way off, help! Also I assume the AF just gets dumped in to my hose coiled on the back of the motor?

After you drain, put all the plugs in except the one at the back on the passenger side. Take the hose off the raw water pump, hold it up high and pour antifreeze until you see it come out the back plug hole, then install the plug. On my GT40, I also used a bucket and some antifreeze and attached it to the hose off the strainer and let it pull some through. I've never used the pink stuff. There's no corrosion protection in it. I read the fine print on the two brands a Walmart. One said it was not to be used in engine blocks. I think it was the Prestone brand and it had "ethyl something" that the other brand didn't. ------------- Tim D |

| Thanks Tim. I am still missing the two plugs on the manifold - see pic,...... where are they? Also, what AF exactly do you use? And I thought it went in the regular hoes you would attach a garden hose to to run the motor? |

The plug on the manifold is on the back, big looking brass bolt. I think that's it in the pic above. It's on the vertical end. I use NAPA antifreeze, it's $9 a gallon, and the 50/50 stuff at wallyword is $12, go figure. ------------- Tim D |

| Tim, I fund the plugs but they are in super tight. I tried a wrench that you would use for a socket -with out a socket to fit in the brass 4 sided hole, but it would not budge.... is this common?? |

Don, a 1/2 inch Ratchet is what I use. Gives a good snug fit and you
get some leverage with the handle. They can be in pretty tight. A 1/2 inch extention will give you some space if your ratchet head it too large to fit in the available space. ------------- 1980 Ski Nautique 1966 Barracuda |

| I cranked on it and either side are budging, I will try with leverage. Are these super important to drain the last bit of water? |

Yes, it is important to remove those plugs, otherise you would have to do the pump though method. I use a breaker bar, you can put a pipe on it for extra torque. You may have to remove the manifold to heat the plugs with a torch if they are badly corroded. In that case, the pump through method might be justified.
I used car antifreeze 50/50 - it came out of my truck, still is good AF! However, I will have to capture it in the spring. Most guys are using RV (pink) AF. Don't worry about the corrosion protection - you don't have any corrosion protection all summer long with plain water in it! Don't forget about the tranny oil cooler, stariner, & RWP, they can freeze too. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

Corrosion protection, which is longer, summer or winterization? ------------- Tim D |

After fighting a stuck plug in my old motor, I use antisieze each fall on all the plugs before I put them back in, seems to make for easy removal. ------------- For thousands of years men have felt the irresistible urge to go to sea, and many of them died.

| obsessed, is he tranny oil cooler just water in there or tranny fluid? |

Both - it has a oil side and cooling water side. You just need to get the water out of it. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

normally the cooler is always vertical and drains, I rarely pull the plug because the AF, will push the remnants of the water through it, but, thats me, today i will probably do 4 to 5 more, 2 block drains, 2 manifold drains, 2 gallons AF. again the more you do on the engine the less chance you take. if you do mess with the cooler be sure to use 2 wrenches so you dont gamage the cooler ------------- "the things you own will start to own you" |

I just pull the lower water hose off the oil cooler. I clean out the water strainer. I pull the RWP & store it in the basement. Pour the AF into the hose leading to the thermostat housing (after draining all 5 plugs).
