Thread: Bars Leaks, been around since landys were invented.

I had an old Kingswood that survived on this stuff & made weekly trips to Oberon for years, stuff never gave me any grief.

Yeah the old Bars works a treat on most small leaks.
My preference has and always will be, to fix the problem properly. But this also depends on the plans and attitude you have for vehicle in the future. This stuff won't do any long term damage and the formula apparently has inhibitor in it.

For me it would always be a temporary thing, but I had a 65 corona which had a myriad of leaks and continued for some years after with this stuff in it, never ran hot, just wore out by itself in the end.

I wouldnt count on it to go bush,but probably fine if around town for a while.

A mate used in in his 80 Series Cruiser and claimed it swelled and softened all his hoses and stuffed his water pump. Cost big $. Now I can't verify that but would like to know if it is possible the product can have that effect.

We used a product called CarGo Sealup in Leon, (recommended by a radiator repair place). It's copper particles in suspension, and when used according to instructions is claimed to even seal cracked heads (within reason I'm sure) Not expensive either and is available in Repco.

Reason we used it was we had a radiator leak and the engine would overheat. They're aren't many places that repair genuine, original radiators, so this product was tried and to date has been ultra successful. I would stress that you must follow the instructions implicitly, which involves flushing properly.

Read 'Nautilus Ninety North' The book written by the Captain of the first US Navy Nuclear submarine, on their shake down cruise (which was ultra secret) they had a leak in their cooling system for their reactor which they could not find, They surfaced at night off a town in South America and a couple of sailors went ashore in civilian clothing and bought up the towns supply of Bars Stop Leak which they promptly tipped into their system....no more leak, Upon return to base a strip down of the system could not find any sign of a leak.......The 'Nautilus' then went on to go under the northpole icecap........so yeah I reckon it is good stuff. I use it.

Yep im with you on this one numpty i have used this in plenty of different vehicles and have had huge wins with it tho you have to follow the instructions to the letter and its sealed up sliped liners in a rover also id say when ron P38a reads this he will also put his 2 bobs worth in as we have both discussed this stuff in the past on here

It does work well and as intended, but if you happen to pull down a radiator after use it does leave some sludgy residue, which in the long term can cause problems. I have seen this first hand in an old HQ I had used it in.

A mechanic I know swears by using ground pepper. But I've never tried it.
He claims it flushes out very easily and completely, unlike the stop-leak products he's tried.
