I'm sure all of us at one point or another have used diluteded vinegar to de-scale the kettle or shower head, all that gets left is dirty looking vinegar with few if any solids.
So it got me thinking, what if i used 50/50 mix vinegar/water replaced the coolant and left it to soak for a few hours. I know vinegar is acidic but if its for a few hrs shouldn't hurt the alloy.
So any, good reason why I shouldn't try it?

Not sure, I've done this with shower heads and kettles, taps, I can't image a weak acid hurting rubber but I'm not sure

same thing as the commercial cooling system cleaners would do...Originally Posted by DiscoMick
regardless of what Im using to clean up the cooling system, (except if Im doing a simple back wash and flush) I always clean up the system using the existing hoses then replace them with the new ones.
my cooling system service sequence is essentially the same for all the engines unless you are running OAT/HOAT or afloc (its a military one) and even then I still do the basic suspended particulates check.
- every service, blotting paper particulates check. (white blotting paper, folded in two and held in a wire gauze dipped into the header tank for about 1m with the engine heated up and running.
- every 12months. Drain flush and replace coolant (or first service after)
- every 24 months drain flush and back wash (or first service after)
- every 5 years ,chemical clean, radiator out water pump off (p gasket for the tdi and inspect
- 10 years replace radiator replace water pump. replace core plugs and welch plugs. (bypass the heater matrix in a disco 1)
so far I've only had one miss with a water pump on one of my vehicles

When you do your kettle, you are getting rid of lime scale. In your kettle a bit of water is lost every time it boils (steam), but the calcium carbonate (lime scale) stays. You pour your cuppa and then when the left over water cools some lime scale drops out onto the surface of the kettle. So I doubt that you would have lime scale in your engine.
Most of the inhibitors would be slightly acidic (but I will need to check if I can get any info about them), if they were caustic then this would eat the alloy away. So using vinegar to clean probably wouldn't do much as any scale buildups would be "used" to acid in vinegar.
A quick check of the compatibility of rubber products against Acetic Acid shows most are compatible except if they are "Poly" type rubbers, like polyurethane etc. There are several websites that show the compability of various rubbers, here's the first one I found:
Rubber Chemical Resistance Chart, Rubber Compatibility Chart - Mykin Inc
So based on the above I think you could but it wouldn't likely do much either way. As a quick try you could take a hose off and try it on just a hose to see if it removes any scale and thoroughly wash it before putting it back on.
Given the complex chemistry that is in the inhibitors I personally wouldn't go messing about with this as any residue that you might leave in the engine may have unexpected results when you put the coolant back in.
