Black Pepper In The Radiator

[Ricardo]

We have a radiator with a slow leak. I heard that I can put black pepper in the radiator to seal it until it can be fixed. My question is, how much black pepper should I be using? A spoonful? A cup full? Has anyone here used it before?

I would solder it before I put anything like that in a radiator. I don't know where you are, but some Harbour Freight stores sell what you need for that.

We used to put a few Tablespoons in. Had like a 20% chance of fixing it. Man that's an old one.

I have heard of an egg doing the trick but never pepper. I will second the Barrs leaks, does the trick but it is better to get the rad fixed ASAP before you cause more trouble.

I too, have heard of pepper but never tried it. One time, I put two cans of commercial leak seal into a radiator to seal a leaky freeze plug. It stopped the leak but settled in the heater core stopping the flow. This prompted me to remove the heater, take out the core and have a commercial radiator man open it, remove the blockage and resolder the core.
Good luck.

Just fix it.

Unless you have an urgent project that you have to finish in a timely manner, take it to the radiator shop and have them fix it for good.

Just my experience..

fix it right ,, why chance a bigger high dollar fix to save a few bucks

We used to have a radiator man in town who boiled out radiators in a makeshift tank over brush or whatever wood he had that needed burning. He "fixed" my radiator by sealing up so many tubes it always ran hot. I had to have a good shop recore the radiator.

Flex Seal. LOL. If it's good enough for a boat....... but then there's that heat element

Pepper was made for seasoning food, not soldering metal parts together. Don't do it.
