Re: Restoring Rusty
so how is it? does it work?
Yes the system works great? here you can see bubbles coming only from the inlet coupling, I did not put any white tape on the threads and need to tighten it some more, but it's a great example of what the leaks would look like posted a video here: Small Block Chevy Cylinder Test DYI Poor Mans Water Pressure Test |

Re: Restoring Rusty
Did you ever figure out the coolant in this pic? Looks almost like a crack but I'm just speculating.

Re: Restoring Rusty
ha ha, not for long I got tired of the red gauge display making me think I am in the red sort of speak so I yanked it and sent it back to Summit for an exchange, I did buy a green one originally after all so I expect an exchange for a green one - is that too much to ask? ha ha

Re: Restoring Rusty
Good morning everyone, just wanted to report that after 500 miles on the new rings and con rod bearings we are still shrapnel free, hee hee
also remember after 200 miles on the new rings I drained the break in oil to replace the rod bearings cause of a slight rattlin noise so far no noises... |

Re: Restoring Rusty
so yanked the radiator to isolate it and pressure test it off the truck, I knew I had a pin hole leak by the inlet but I was wondering if there are other leaks as well, nope
picked up these 1 1/2" expansion plugs at NAPA they seem to do the job well looks like the radiator cap lets go at 10 PSI, oh well that's good enuff I think |

Re: Restoring Rusty
using some high tech equipment here folks, let me tell you that
rocket science this is not, don't be skierd, the overflow nipple worked well to hook up the bicycle pump and fill it with air |

Re: Restoring Rusty
well with no glaring problems with the radiator we moved those expansion plugs over to the inlet and outlet rubber radiator hoses leading to and from the engine and plugged them up

Re: Restoring Rusty
just like we did with our test cylinder head, we are going in through the water temp sending unit hole to put air in the engine
we were gentle as to not blow up the water pump seals, so just to 10 PSI I removed the valve covers so that I could see some bubbles if any or hear some hissing, but no, none of that I also removed the spark plugs to see if I can hear anything in there, nothing, by the way all plugs look the same, so #5 is purdie now I left the engine pressurised at 10 PSI while I write this up, we'll see if it drops or stays level |

Re: Restoring Rusty
I'm enjoying your diagnostics. You should send these photos to Zefal and show them what a precision instrument their tire pump turned out to be. They would probably be impressed. Or tell you that your warranty was void.
I'm hoping you find something that is easy to fix, or that you had just managed to work out an air pocket. Good luck man. |

Re: Restoring Rusty
One of the pressure tests I typically do is to pressurize the system and run the engine. If the needle doesn't fluctuate or drop like a rock I don't usually have a problem.
You can get cooling system pressure testers from AutoZone's loaner tools. 10PSI is a little low for the radiator cap. They are usually rated for 14-16PSI. Every PSI drop is @ 4.333333°F lower boiling point. Pure water boils at 228°F at 10PSI vs 254°F at 16PSI. 50:50 Coolant:Water will raise the boiling point around 10°F.

Re: Restoring Rusty
Thanks HATZIE so could i be loosing coolant via the radiator cap in the form of vapor on the account of it releasing pressure too early at 10 PSI rather than 15 PSI?

Re: Restoring Rusty
It's possible. If you don't have a catch-can/overflow-bottle or the bottle is smaller than the overflow volume you're likely just blowing it out on the road.

Re: Restoring Rusty
Never heard of them before a few weeks ago. They had a booth set up at Goodguys in Ft Worth. They had hats and t's for $10 each. Since that's about the same price as a bottle of water at GG's, I bought one of each.

Re: Restoring Rusty
well it's been 24 hours and the pressurized engine (block, heads, and intake manifold) are still holding 10 PSI, so I am going to order that new Northern aluminum radiator this week after I get paid, and we'll change one thing at a time till we find the source

Re: Restoring Rusty
If the Aluminum radiator is a good idea today it's still going to be a good idea in a couple days...
Try changing the cap to a Delco 10409635 (RC27) or STANT 10230 rated at 16PSI. The fill neck could be borked but I'd replace the cap first. It's cheap and you can always order the Aluminum radiator on Tuesday or Wednesday if you still want it.

Re: Restoring Rusty
so the first thing I did was test the radiator cap, and it holds 15 PSI easy, no leaks, hmmm
this seems like a pretty nice cheap kit for an amateur, I'm sure the metal one would be better for a many uses, but for a one time deal, it does fine |
