Auto Coolant Additive
« on: August 03, 2013, 09:44:37 AM »
I've had my '91 Honda CRX Si 22 years this week .

I've had the worst experience with failing water pumps on this vehicle than any other water cooled car I've had, they usually fail around 3 years, with coolant leaking out of the 'weep' hole in the water pump casting .

About 5 years ago I learned of a product, Water Wetter, the manufacturer claims it reduces operating temperature by modifying the cohesion characteristics of water on the metal of the engine.

You use 1 fluid ounce of additive, per quart of cooling system capacity .

It also has a lubricant of some sort in it for the water pump .

My current water pump is going on 6 years now, no leaks so far .

Can't say I see any difference as far as operating temperature goes, but it seems to have cured the early failure of the water pump .

I get it locally for around $10US for a 12 fluid ounce bottle .

I change the coolant every three years .

As so many newer motorcycles are "wet", I'm seeing ads for "water wetter" products in most all the bike mags. Perhaps my water-pumper Triumph Triple might benefit from a small dose.

FLAPS sometimes refers to them as a water pump lubricant. Maybe keeps the seals flexible for a longer time period.

Stuff must work. Like, they couldn't run those ads if it wasn't true... right? :)

I believe that those products are not welcome at official racetracks, as, in the event of a crash and spillage, the stuff is really very slippery and doesn't dry up quickly.

I've thought about trying it in my Kawasaki Concours, but I've been a bit scared to as it has been rock solid-reliable for 15 years now, and I just use the Kawasaki coolant and distilled water in it.
