Hi all,
Anyone used this stuff? My Tuscan has been running a little warmer than usual lately with a good run putting the water temps up to 94 (1st fan on) then 96/97 (both fans on) and can take a good while to cool things down again (maybe 6 or 7 minutes with both fans on to cool back down to 93). It had a service with full replacement of coolant recently. Normal driving at anything over 40mph brings the temp down to around 85 but it soon climbs up to mid-90's when idling, as might be expected.
Anyway, I thought I would try out some water wetter and put the whole bottle straight in. Took the car for a run to see if there was any impact and there doesn't seem to be any difference at all. If anything it seems to be running a little bit hotter!
Any comments?

I have never used it.
In your case, I cannot help thinking you are trying to cure the sympton, not the problem. If the engine temp is warmer than it used to be, that is because something has changed. ( It could be anything, rad getting dirty or blocked, thermostat not openeing at the same point, some pipes getting sludged up, or even an engine problem meaning it is making more heat ). Whatever has changed, you would be better curing that than using water wetter to make things OK in the short term, but you still have not solved the reason that the temps are higher.

Agreed - check the levels and make sure there aren't any air locks.I've used Water Wetter in the past, and it does help keep temperatures down a touch, HOWEVER it will only help a good cooling system work more effectively, not solve an overheating problem.
hmmmm, yeah - I reckon you are right guys about symptoms/disease etc. However, there hasn't been a HUGE change in the general running temps of the system of late, it has pretty much always ran at those sort of temps but perhaps 1 or 2 degrees lower or perhaps a longer time to get to those sort of temps. With the recent service/coolant change, I did assume that the system should be ok and I would see a change when adding the WW.
I'll keep an eye on it, it never actually overheats or goes above 97/98C (might flicker to 98 for a second or so) so that's good but maybe the engine itself is producing more heat than it used to. The de-cat shouldn't have had an effect, should it? Maybe it's the sender unit?

Water Wetter is essentially soap. It reduces surface tension and allows a better thermal transfer between your engine and the water itself.
Note I said "water." If you have any half-decent coolant in your engine, Water Wetter will offer you no additional advantage (except providing a lighter wallet).

I use it in the 400SE and in Tuscan 13 and it drops the temp by around 8 degrees in both.
Wouldn't be without it!

8oC sounds about right... borrowed an IR thermometer thing and it certainly showed a decrease in temperature.Wouldn't be without it!

That said the Chimaera's cooling system was bloody good. 42oC in Spain, sat in traffic, only one fan working... it crept to 95...

That's a good point, with a recent replacement of coolant, I wonder if there was any actual water in there at all....will give Fernies a call to check what sort of ratio (if any) they use.Note I said "water."

Thanks!

Some people, myself included, use pre-mixed coolant which will have no benefit with Water Wetter added. I've tried.
I use Comman Coldstream because it's a Propylene Glycol mix. Far better for the world than the Ethylene Glycol mixes which are quite nasty/hazardous.
Coldstream is a bit hard to find these days. Wilkinson's had some in 1 litre bottles last time I looked, so I bought them all (9 bottles).

I was looking for some water wetter and my local Halfords desn't sell it. I need to replace my water pump and the hoses and thought it may help keep things cooler, not that it runs hot, but the temp does creep up very quickly if stationery in traffic but drops just as quick once moving.
Not sure if its worth the bother now reading your comments.

Exactly the same here Andy, as I posted before both oil and water reaching higher temps quicker, to the extent that I haven,t had the confidence to bring it back to Italy for the first time in 3 yearsAnyone used this stuff?

, I tried water wetter but it made no difference at all.As others have mentioned I think the cause should be explored rather than the effect- can you keep us updated?
