Where’s my water going?
I’m nervous about this issue. It seems I am having to add to the radiator every time I drive it or it overheats (or every few drives). I only have about 150 miles on it and it’s running great but if I drive a few drives, it gets hot and I add water and it’s fine. I’m nervous about where this water is going! My oil level is not changing, I see no water on my garage floor. Is it possible there’s a small leak allowing it to get into combustion chamber as I’m driving? I did the bubble test (remove radiator cap while running and look for bubbles) and I’m not seeing any bubbles. Thoughts?

Re: Where’s my water going?
Most of these old Fords of ours will spit out water from a full radiator until it finds its own level, usually just above the radiator core. This is normal. How hot is your engine getting?

Re: Where’s my water going?
Yes, I was trying to let it find its own level until it started to get hot, like 200-210, sometimes up to 220. I have a guage on both sides to watch temps as I drive. When I fill it, it stays around 180.

Re: Where’s my water going?
What pressure cap do you have on it?

Re: Where’s my water going?
Water might be boiling off due to a leaky head gasket, this given to the few miles on the engine. Next time you refill the radiator, do it with the engine running and look for bubbles in the water. What type of head gaskets did you use. Have the heads been retorqued?
BTW - You really did a good job on that car of yours...

Thanks Pete. It’s certainly been a labor of love. I’ll check for bubbles again. My hunch says it’s overflowing ever so slightly out of the over flow tube but wouldn’t it eventually stop doing that when it finds the level it likes? Does anyone ever put an overflow tank on these cars?

Re: Where’s my water going?
7ib cap is more than likely max for a stock radiator with stock upper and lower tanks.
for every 1lb of pressure you increase the boiling point of water by 3 degrees. So with a 4lb cap your actual boiling point is 224 degrees, so you are on the cusp of this temp once the water level drops. Do you have a recovery type cap (2 gaskets) and a recovery tank, what this does is as the water expands it lets the excess water go into the recovery tank, as the water cools down and shrinks the radiator sucks the water back out of the recovery and back into the radiator. |

Re: Where’s my water going?
How much water are we talking about , ?
You could pull plugs when cool and inspect for moisture or a different color plug from the rest . |

Re: Where’s my water going?
You didn’t mention what year radiator but if its a designed non pressurized system your simply losing coolant when you get up to speed.
Install a 4 pound rad cap and at the end of your overflow tube install a 2 pound brake residual valve. The valve is installed to maintain a slight pressure in your system and will maintain your coolant. |

Re: Where’s my water going?
When you add water, how much do you add before you see water? 1 quart, 1 gallon?

Re: Where’s my water going?
I installed a 2 lb. check valve at the end of the overflow tube that I purchased from Skip Haney in Punta Gorda, FL. Worked great to keep the water in the radiator. Someone here will give you Skips contact info or do a search on this forum.

Re: Where’s my water going?
Have you done a pressure check on the cooling system?
You can also use a Ultra Violet leak detector dye kit. https://www.bing.com/videos/rivervie...1356&FORM=VIRE Question: Are your radiator hoses collapsing inhibiting coolant flow? Remove the thermostats and see if there is any difference. Last edited by 19Fordy; 04-24-2024 at 08:56 AM. |

Re: Where’s my water going?
Radiator is a stock (new) 40 unit.
I add about 4-6 cups of water every few drives. I do somewhat suspect thermostats so I’ll remove those too. Any photos of those check valves installed?

Re: Where’s my water going?
One quart isn't a lot. You might be pushing that out the overflow at higher speeds. If you are only adding 4 cups that should not cause an overheat. When you say it overheats, does it boil over or steam?

Re: Where’s my water going?
where is your orig radiator, can you use it, member here had a real bad time with a new Drake rad overheating . And that system was not made to be pressurized .

Re: Where’s my water going?
I believe you have a fresh engine. The last one I had built (a 327 SBC) must have been built on the tight side of tolerances, because it would overheat if I let it idle for more than a couple of minutes. I checked everything and found nothing. I was just get ready to tear into it when the overheating problem just went away; I think it just had to "break in". If the engine is fresh and you don't see any obvious problems, I'd give it at least a couple of thousand miles to come around. Just keep an eye on it.

Re: Where’s my water going?
I didn’t see where the question about re-torquing the heads got answered....maybe I missed it. I would re-torque the heads and make sure not to let it boil over while running it for the break-in period......Mark

Re: Where’s my water going?
I believe he has retorqued and replaced head gaskets.
It is a good point about a new engine running hot for a little while. You can richen the mixture to cool it off for a couple hundred miles, then tune the carb and clean the plugs. What is the coolant level in the upper tank when you have to refill? You are right, the coolant is either going somewhere it shouldn’t, or it’s finding a normal level.

Re: Where’s my water going?
I guess I will try to be more patient and see what happens in a few hundred miles. I did have seeping head studs, but all of that has stopped. Heads have been retorqued probably 10-12 times (overkill) after every single drive after any drive in which the engine was warmed up. It is to the point where when I retort them they are all on spec.

Re: Where’s my water going?
Oh Pete…the head gaskets caused me all kinds of issues when I installed them. I’ll see if I can dig up the thread. I had a ton of leakage with copper so at the end of the day, I ended up with the graph tite gaskets and that stopped my leaking into the cylinders (or so I hope). This is why I’m so paranoid about water finding its way into the cylinders.
Here’s the head gasket thread. https://www.fordbarn.com/forum/showthread.php?t=333499

Re: Where’s my water going?
Here’s my plugs. I thought I was running rich but I guess not. Might be running a little lean? Anyone have thoughts on these? I’ll resize when I get to my computer.

Re: Where’s my water going?
Please don't be offended, have you retightened all your hoses since the install ? You may just have a couple of weepers where the coolant evaporates as it seeps out. Sometimes we over think things. I was surprised at the depth of you spark plugs . The Edelbrocks I ran back in the 80's definitely didn't have that much thread depth. Tim

Re: Where’s my water going?
I confirmed when the heads are off that the plugs fit perfect. The electrode just barely stuck out into the chamber. These are actually what Eden rock recommends.
Pistonbroke, it’ll take way more than that to offend me! I have checked tightness of clamps and such. When I first started the motor, some of the studs weeped. When that happened it “stained” the new heads. Once I was pretty sure they stopped weeping, I cleaned the heads and so far, there are no signs of the same stains I had when I knew they were leaking a touch.

Re: Where’s my water going?
Try the pressure test again….and try it with the motor up to temp….next thing is a catch can on your overflow tube. Put the tube all the way to the bottom of the container, with it cut at an angle…….Mark

Re: Where’s my water going?
Nothing to do with the original post, but it looks to me like the Plug Number starts with an "R". I think on Champion that means "Resistor". Are you running those plugs for any particular reason?

Re: Where’s my water going?
This is from the Edelbrock web site. "Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat"
