Pretty easy one here. Does anyone add this to their coolant?

 

No I had a bad experience in my Mustang with it and have heard of a few friends having the same luck in their BMW's. I stay away from it.

 

No, and I haven't heard much talk about it around here in the past 5 years.

About 10 years ago, some of my off-roading friends used it in their trucks that had overheating problems.

I generally consider most additive products to be generally unnecessary.

 

I tried it before in my BMW.

It clogged up the tubes where the coolants move in. Maybe its the car too as the E46 was famous for using up coolant, so that and the fact that water wetter dies up wih residue.


It's rubbish.

 

E46's arent famous for using coolant. I think thats just yours...

 

Yes they are in tropical climate.

 

I use it in the watercooling system of my computer, but haven't put any in the car yet

 

Had it in mine since it was inspected over the summer and have had no issues. From 18 degrees last week to over 100 in July and August. Interior seems to radiate heat a little more with it though which this time of year is nice.

 

I ran it in my 94 Mustang GT. It ran a notch cooler according to the gauge. I've never had over heating problems with the MINI, so when I do change my coolant, I won't be using it.

 

Yeah...mine was a '92 5.0 GT running almost 600HP...it actually made my overheating problems worse.

 

Water Wetter is not intended to reduce your overall coolant temperature, although in some cases, it may. But in cases where your cooling system is already marginal for the amount of horsepower you're making, using it can actually cause the bulk coolant temperature to go *up*.

What it's designed to do is reduce "hot spots" inside the cylinder head cooling passages where steam pockets have formed, preventing the transfer of heat from the cylinder head to the coolant flowing through the passages.

I've never needed it on a street-driven car, but I know that there are some race tracks that don't allow conventional coolant in the cars, so in those cases, distilled water + Water Wetter is a good option.

 

Scott is exactly correct...using it on the street is probably a waste of time, but I use it on my race car, and as a test, we kept my teammate's Mini in it's stock configuration. When we came into the pits, his fan immediately went on and stayed on for about 10 minutes....mine never came on, which I thought might be a fault, but wasn't....the underhood bulk temperature was lower.

Also, we change fluids so often relative to a street car that the issues noted by others are nonexistant.

WaterWetter actually is used by some drag racers, as they cannot use glycol-based fluids at the track...the few guys I know swear by it.
