ground white pepper... i kid you not, ran my hj45 for 3 weeks with it, through little desert and everything through summer...

Egg whites work very well.With a tube of Knead It to stop up the big holes.

And then there's Chemi-Weld and another one called Aluseal.

chemiweld doesnt really work on radiators only on heads and weld plugs etc.

I think kneed it or radiator putty is about all that definatly works

good coolants generally have a penetrating effect and can cause leaks, i used a stop leak not that long ago and it worked. Had heaps of chunky bits in the bottle, just go to as place like repco or burson's & pick one off the shelf

Its not recommended to use stop leaks in some efi cars with sensitive sensors, it can block up important bits...so make sure read all warnings.... But older trucks is possibly ok..christover

I have heard about the pepper or egg white trick, have never known anyone that has tried it. Last resort hey.

As for the Chemiweld i looked at that but as said its more suited to block & head cracks etc.

Big Red Toy, i was looking for the one you mentioned with the round pellets floating in side......any idea what it was called ?

AS a "just in case", I've found Bar's Leaks to be great. When I went to Rover Park, the Mav' developed a leak in the four week old 3x core radiator. Dumped some of this stuff in and it worked a pearler. No leaks all weekend.

Regards

Bars leaks is an excellent product, in my opinion. It did a repair job on a leaking welsh plug whilst on a trip, and stayed fixed till I did a real repair about 6 months later. Funnily enough, when you open it, it looks like pellets of ground pepper and egg white. I think it does affect temp senders, ect, as mine under reads the temp, as I still havent cleaned it yet. Be warned, that it will clog leaks, and also radiator cores.
As for using pepper and egg white, I have done that. A few years ago while doing duty at a driver reviver in country queensland, we had a Commodore ute limp in. A rock or something had been thrown up by a passing truck, and holed his radiator. We fixed it by pilling the radiator, cutting and folding back the affected core, then refilling and putting in a generous serve of pepper and 2 egg whites. We had about 20 people watching bush mechanics in action.
Next day he passed back through, and stopped to tell us that it worked ok. I think he ran with the cap on the first notch for a while, but at least he was mobile again.

I would only use an Egg white in absolute despiration. Have any of you guys used this and then had to carry out repairs on the cooling system afterwards. Its not a great smell.

I always use Saxa Fine White Pepper. Have used it 10 or more times with great results. The small shaker is the perfect size. Just pour it all in and it will seal any external hole.It just coagulates as it passes through the hole.

Not much apart from Chemi Weld will fix a leak that is also effected by compresion(headgaskit or block)

I ran chemi weld in my VL for over 2 years to seal a headgaskit i couldnt be bothered fixing

A couple of weeks ago I discovered a leak in my old Cruiser's radiator I can't remember the name of the stuff I used but it comes in a clear plastic bottle & the solid part of the solution is a coppery colour. It seems to be available everywhere & it certainly stopped the leak although I did follow the instruction to the letter. From memory the active ingredient was some kind of silicate.

It's called seal-up and beats chemi weld hands down, I have used it as a permanent fix on my zooks blown headgasket as well as a 3y and countless Falcons

A mechanic i was talking to said he didn't like this one because its oil based & hard to remove from the system later.

I tried this stuff on a leaking water pump. It didnt work for Shit and i used 2 tablets. The water pump was hardly even leaking to start with.

Thanks for this i will remember to never buy a motor from them. This is a great product to make sure an engine gets through its warrenty period with no head/headgaskit problems :roll:

I agree !
Sounds dodgy to me.

A sealent is unlikely to work on a waterpump Ruff as you have a graphite seal running against cast,No black magic potion will work there
