Kinda dumb question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

How much water (or antifreeze) would it take to fill up the raditior in a 76 k-10 with a 350? It is at someones house and I am going to go and try to start it, but the cooling system is completely dry and there isn't really a hose available.

try putting equal amount of water and antifreeze until it is full...

To be safe take 4 gallons (2 water, 2 antifreeze). This should me more than enough including the reservior and all the water being in the block. Make sure to get all the air out of the block as well.

Ok, so 4 gallons should fill it up? The reason for my question is that the truck is about 1.5 hours away, and there really isn't a place to get water around where it is.

My Haynes manual says that 1975 through 1987 (all models) with the 350 have a capacity of 18 quarts (4.5 gallons).

The 6 cylinders hold 15 quarts, and the 400 small block and 454 big block each hold 20 quarts.

To be safe, I'd take 5 gallons. It's not like you're never going to use it again!

Yeah I say take (2) antifreeze & (3) waters just to be safe. I have a 350 with a 4-row monster radiator and I never use more then 4 I think, but im not real sure. If your going to be buying water in a bottle you should buy distilled water. It does not harm your engine/motor as much as regular water. Less deposits and rust. I have been puttin nothing but distilled water in this engine ever since I got it (new crate 3.5 years). When I did the intake swap I was suprises at how clean it was. I usually change my coolant/water about every 12-18 months. Which is pretty much when something breaks

If you havent ran the truck in awhile and dont know what to expect. I would bring a few extra gallons of water to flush through the engine before you start it, just to get some crap out if there is any. What about hoses? Are you sure the hoses are all good?

It has been sitting for about 8 months, and someone tried to start it a couple of months ago and it would turn over but not fire.

No, the hoses are pretty dry and stiff. The radiator is completly empty right now, and I just need to see if I can get it running well enough to get it home. I would buy hoses, but I don't want to buy hoses and then start it and find out that it has a rod knock or something and have wasted $30 on it. (it would be different if I was paying for the truck, but if I take it it will be free, so...)
I think I will just take 5 gallons of water, because I would have to drain it to replace the hoses to bring it home anyway. After I change the hoses then I will put antifreeze and distilled water in it. I am probably going to go work on it on sunday, so I will let you know what happens
