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
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.

a Northern Radiator ad, (again never heard of these guys either) |

which led me to this
actually a smokin' deal on an aluminum radiator for a V8 small block with a manual transmission for only $271 CORE DIMENSIONS: 28 1/4 x 17 1/8 x 2 1/4 OVERALL DIMENSIONS: 33 x 18 3/8 x 3 1/8 |

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. |

so my plastic [ahem] PVC Mityvac MV4560 coolying system pressure test kit arrived from Amazon today, they deliver on Sunday's who knew?!
$50 bucks |
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 |
Re: Restoring Rusty
Yogis been around a long time. Mostly known in the street rod world. Cool little you got there.

Re: Restoring Rusty
alright I just put a 7 PSI pressure test on the engine (heads, block, intake) chose 7 just cause it's a bear to pump that little guy up, plus 7 is in the geeen zone, so we'll see if it holds

Re: Restoring Rusty
Checkout Champion too, I got a 4 core monster for my 383 from them for a hell of a price, and it's a high quality radiator too.

I give you the world's dumbest invention, radiator hose lube, this is excellent if you want your hoses to slip off the inlet or outlet tubes no matter how tight you make the hose clamps
you can find these right next to blinker fluid at your local parts house |
Re: Restoring Rusty

When the bead on the tube and fitting ends is properly formed and the clamps are sufficient for the task it causes ZERO problems and the hoses don't end up bonded to the fittings. If that stuff is petroleum based you will have issues. Quote:
It also gives you access to "included with Prime" movies and commercial free TV shows kinda similar to Netflix. I paid for this season of Dr Who and The Blacklist on Amazon Video but there are a lot of included videos. |
