Red Line - Water Wetter

[patroldude]

Hi Guys, i have read a bit about Red Line - Water Wetter it appears to be OK. Would love some real world feed back on it. I drive a 2000 4.2TD Patrol and am looking at dropping the temp just a little bit, thought this might help. Any feed back would be greatly appriciated. Cheers

WaterWetter®
Unique agent for cooling systems that doubles the wetting ability of water
Rust and corrosion protection allows for use of straight water in racing or reduced antifreeze levels in warm climates
Improves heat transfer and reduces cylinder head temperature
May allow more spark advance for increase power and efficiency
Use one bottle for most passenger cars and light trucks, treats 3 to 5 gallons or 13.2 to 15.9 liters. Vehicles with larger cooling systems should use two bottles. Small cooling systems should use 1oz (3 to 4 capfuls) per quart
Compatible with new or used antifreeze (including DEX-COOLTM and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes


ABOUT RED LINE WATERWETTER® COOLANT ADDITIVES

Reduces or eliminates bubbles or vapor barrier that form on hot metal surfaces to reduce coolant temperatures by up to 20°
Superior heat transfer properties compared to glycol-based antifreeze
Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
Improves heat transfer and reduces cylinder head temperature
Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
Cleans and lubricates water pump seals
Reduces cavitation and complexes with hard water to reduce scaling
Does not lower cooling system below the thermostatically-controlled temperature

Have you had your cooling system flushed and reverse flushed at all? It works wonders.

[patroldude]

Yep, sure have, happy with the EGTs under normal conditions - just wanting to drop a few points when climbing some of those real big ranges etc. hence the query about the Red Line product. Cheers

What about talking to a radiator specialist about fitting a lower temp earlier opening thermostat ?
 We have fitted 10 Degree cooler thermostats to all our vehicles over the years with no issues of over heating etc.. might be worth a chat to see what they think .

[patroldude]

mmm worth a look, thanks for the option. Cheer

I tried it in a 2 stroke race quad years ago without much luck, however their 2 stroke racing oil is amonst the finest on the market.

Fitting a cooler thermostat only affects what temperature water begins to circulate. If all other things remain the same the temp will still rise in situations where there is extra demand placed on the cooling system.

Power flushing is okay if coolant is dirty or if engines are particularly scaly, however the only accurate way to know if a radiator is working at maximum efficiency is to remove it from the vehicle, have a tank removed , and have the core cleaned (rodded).

Occasionally the culprit is the viscous fan drive, which when a vehicle starts to cover a few km's can loose it's efficiency or won't always "re-engage" drive, as engine/coolant temp increases.
I also strongly believe in external transmision coolers for automatic vehicles.

My opinions above, are based on Perth conditions, and knoweledge gained from 22yrs spent working on vehicles in the cooling system industry.

Hope this helps, David.

Thanks for the heads up David. Cheers

I agree with David, thermostats are an important part of the cooling system, they typically:
1. Control temp
2. Allow an even warm up of the engine, the water is bypassed back to the pump
3. A pressure regulator, this is often over looked, they give back pressure to the pump which ensures the pump works correctly and also the fluid reaches all parts of the engine.

So when messing about with thermostats, they must  be kept the same as the original type.

Opening at a lessor temperature is of little advantage.
Being certain that is functioning correctly is most important. That is, it is fully open and closes the by-pass circuit? If a small amount leaks past bypassing the radiator that will be of note when under extreme loads such as you describe.
Hope this helps
