Seems a bit odd to me but have any of you guys used or heard of vinegar being used to flush out an engine and cooling system?

Just wondering.

Not vinegar but I've used dishwasher tablets and cheap (non diet) Coke and both work well.

Used it years ago to remove limescale , had to leave it in the block overnight. It was quite effective.

You can save a small fortune on cleaning products all around the house by using cheap vinegar. Very good for cleaning windows as well, try this book https://www.ebay.co.uk/itm/Vinegar-1001 ... ctupt=true

I found a pack of cheap denture tablets good as well (as well as cheap Cola). Not tried vinegar yet but should work in a similar manner.

Certainly as good as, if not better than, “bespoke” cooling system cleaners which tend to come in a posh bottle at a considerable cost.

That's the chap - I ordered five and just filled up some tubs for my de- rusting of parts - four years on it still works - but you need time and patience , every so often I filter the tubs , even used to clean up some 30 year old angle iron - came out like new

Cheap white vinegar is amazingly useful for all sorts of things. I homebrew a shellac-safe record cleaning fluid using white vinegar, as the stuff my husband uses on his LPs is mostly isopropyl alcohol, which is a no-no for 78s. It works a treat, though to be fair some of the credit has to go to the record cleaning machine itself.

You can get large jugs of white vinegar very cheaply in groceries as it's used in making pickles, and it rinses clean (unlike cola). Diluted vinegar would be my choice for a radiator flush, though to be fair I haven't done one of those in more than 20 years.

So the cooling system was drained off and the water was clear enough but it had a hint of pink antifreeze in it, undid the thermostat housing bolts and my suspicions were confirmed, no thermostat fitted. Refilled the system with fresh water and dishwasher tablet then left it for 24 hours. Drained off the clear water and flushed again, a new 88 degree thermostat was installed, the sensor for the Kenlowe was fitted as it had been operated by a direct switch and the cooling system was refilled with fresh water for a test run, warmed her up and took it round the block and out onto the main road for a four mile run and the gauge sat steady at high eighties to ninety degrees, returned home and sat at idle for a minute, kenlowe kicked in so I switched it off and the fan continued to run for about four to five minutes before finally stopping.

Just wondering what you Kenlowe users have yours set at and how long does the fan run after switching off.

The fan needs to be set just above the temperature at which the thermostat opens, most Scimitar fans are set at just over 90C. That having been said, one of my bikes opens at 85C but the fan comes on at 105C with overheat warning at 115C.
