OT: radiator leaking ??
Posted by: larry cooper ()

Yes, I know Corvairs don't have radiators, well - there are exceptions. I had to have a new front crankshaft seal on my GMC PU replaced. My mechanic ask me if I knew my radiator had a leak, I didn't, but wasn't a big leak. I remember in the past some of my vehicles would spring a leak and I would put a powdery product in it ,or sometimes I put pepper in to stop the leak. I told him I would get what ever and put it in to stop it. He said he used something different and it was better than pepper or the powder from a flaps . He said he put mustard in the radiators, yeow, hamburger dressing. I had never heard of that before, but he has been a mechanic for many years so I took his word for it. I put about a cup of mustard in, and I don't have a leak anymore. A word to the wise (and others) I bought a small plastic bottle of mustard,( be sure to shake it well) then squirt it in the radiator. Be sure the coolant level is down somewhat so the mustard will have room to go in.
Maybe some of you already know about this quick fix, but, even though I have been around cars longer than many of you have been here, it is nice to learn something new. Larry Cooper

An egg works as well! I have done that several times over the years. Most recently, sealed a coolant leak from the intake manifold in my father in laws Lincoln town car. Until I got around to replacing the intake manifold. Not a permanent repair, but works in a pinch!

Comic relief - me replacing said intake manifold. I did kinda crave a mcmuffin the whole time!

Hmmmm.
Interesting, but are there any "side-effects"?

If you have a leak, this is what I use. Not many folks know this but when they went to DEX COOL with aluminum engines, GM and other manufactures started adding this stuff. They threw a pellet in the lower radiator hose at the factory for many years. The aluminum Cadillac Northstar engines had you adding some every year as a maintenance item. Its made from ground up ginger and walnut shells. It shrinks when it gets wet and swells when in contact with air. The military was using it long before that. I know this stuff works and its cheap. Not as cheap as eggs or mustard.

If a water pump is leaking a little...my ol mechanic told me add a spoon full of brake fluid to the radiator...it swells the rubber parts in the WP and stops the leak.

+1 on the bars tablets or the Delco version. I have used them for many years with no ill effects. I stretched the life of a radiator in a caravan 3yrs/36k miles with it. I put so much in that the coolant wouldn’t go through a paint strainer when I finally replaced the radiator and tried to reuse the coolant.

As far as mustard, eggs, pepper, oatmeal, brake fluid...they might get you out of a bind in the short term but just like any stop leak, it is temporary. I don’t think I would want to reuse the coolant with homemade stopleak in it.

My ol mechanic (very old school) said banana peels in the rear end will make the singing rear end noise be quiet.

If you have a leak at a fitting, wrap some COTTON string around the line/fitting and the leak stops....like on our cars with auto trans at the pan.

This mechanic was so good..(he was the top mechanic at Chevy, was assigned to corvette)...when he quit the dealership, the owner came to his house and begged him to work on their cars at his house. He stayed busy without the dealership.

I had the benefit to spend a lot of time with him in his later years.

If you were lucky enough to have him work on your car...you had the best there was.

I never saw a vehicle where the GM tablets had been used that didn't have some form of diminished heat output from a partially blocked heater core.
Maybe just my bad luck?

I, personally, have never added anything to any of my systems...if they are not working as required, fix them so they do or get a quality replacement.

I think the banana peel was a 1930's fix back in the day.

Heh.
I always heard that shady used car dealers put Oat Meal in howling rear diffs. to quite them down temporarily.
Guaranteed! Thirty miles or thirty minutes which ever comes first!
