Do it right, the first time, and it will be cheaper in the long run.

Tom: Black pepper, no question has all the commercial products beaten by a mile. I fixed a hole size of a lead pencil, in rad of a Chevy dump truck 366 engine. 100,000 miles later it was still going. I have used it numerous times over the years in mainly cars and trucks, and never pluged a heater core. I think my old 6.2 Chevy diesel probably saw 2 lbs of pepper over the years. I recall about 6 times forign objects left holes in two rads. Truck went 400,000 miles in 14 years, never had a new heater core, required two rads and one new water pump. The new rad was result of little towing accident, water pump happened at 350,000 miles. I don't ever recall having to put any in a tractor.

In my home turf highway salt was the big curse on rads, mainly cars and trucks. Tractors tended to be immune from that.

irontite comes in red and blue formulas. sold at car quest and many other places. reason i rec. irontite over bars or such is because bars works on the idea of clogging the hole irontite does not clog


Seal minor cracks and leaks in the cooling system - prevent anti-freeze leaks
Lubricates water seals
Fast-acting, non-corrosive, non-clogging
Can be used with coolant or anti-freeze


i recommend though that the leak be taken out and fixed correctly but if not possible fiesable wahtever irontite is my vote used it and works great

Depends a lot on what it is exactly.
I"ve used Bars Leak lots of times with success, but I am particular in what circumstance.
A rad with a separate core - dismantle and seal the offending tube(s)?
Non pressurised system - no problem as most stoppers will work.
Pressurised systems are more liable to give a bigger problem if sealant fails when pressurised, esp. if the failure is due to lengthening area of failure.
If it is out of sight or not important if seen, I have used body filler to effect a permanent? repair as long as damaged area is not too large a percentage of total cooling (once on my brother"s Into 454, after the fan gouged almost a complete circle in the rad!).
Best repair advice is to change it, if it is a modern flimsy arrangement or if any cost saving now is likely to be exceeded by any possible failure later. Even uncovered diesel injectors can easily be fried at the nozzle.
The aggravation of a blown head gasket can be more than enough of a problem and a cracked head is a disaster, compared with a proper rad repair. Remember some engines and most modern ones are very unforgiving if allowed to go low on coolant.
Your choice in the end though, but don"t blame us.....
Regards, RAB

If you can find some Bull Durham, works as well as anything I've ever tried.

heard some old timers tell of using rice and oatmeal. would stop most any leak. probably would clog water pump eventually.

My cousin fixed a radiator on an old car with raw eggs. Dumped the egg in the radiator and ran the car until hot. He said it worked o.K. Anyone ever try this?

I'd use Bars Stop Leak in a tractor. If it doesn't work, you can always fix the radiator. In a car/truck, fix the problem as stop leaks will usually plug up the heater core, sooner or later. That gets very expensive.

The best stop leak I have ever found is black pepper. I used to do dirt track stock car racing where radiator damage was common from rock or collision damage. One of the other racers put me on to using black pepper,it will stop up a hole nearly as large as an entire radiator tube in seconds.I never found a commercial product that worked as well. The stuff seems to stay fluid untill it is exposed to air at the leak,where it hardens into a plug.I never found any internal pepper plugging of the radiator when I washed them out later to make a permenant repair. With the race car,you had pure water in the system and no heater core to worry about plugging. I never had the courage to try pepper in anything with antifreeze and a heater untill last summer. The top tank seam opened up about 10 inches long on a 45 year old farm truck that sees a few hundred miles per year during harvest. we badly needed the truck that day so I thought I would try an emergency fix with the old pepper race car stopleak trick. We never run the truck in the winter,so I was not too concerned about plugging the heater core. I added a couple teaspoons of pepper to the antifreeze coolant in the radiator and put it back to work. The leak sealed within a couple miles. The radiator leak is still sealed 6 months later and the heater works fine :-) Pepper is a non corrosive,biodegradable product that makes the coolant smell like nicely peppered soup.
