I've never seen it sludge anything up, but some have posted that it has for them. I can only assume it is dependent upon 1) if the cooling system was serviced according to manufacturer recommendation, 2) if WW is compatible with some antifreeze chemistry but not others, or 3) vehicle application. Maybe a combination of either or all.
Just curious, did you notice any [even placebo] of the vehicle coming to optemp faster? Or keeping cool under stress/hot days?
I see the stuff sold along side VAGs Gxx coolants on nearly every OE/OEM parts store; online or brick and mortar. So i assume its safe. Just curious about its worth even if just placebo.
I dont buy into the whole 'it's for racing'. Only because the argument is.... 'It's not going to do anything for a normal 50/50 coolant/water application because its for race applications where the track has a ban on coolant.' This to me is implying that 50/50 does a better job than water. Therefore these straight water applications need a little boost.
Now these race applications may in fact need a little boost just because of the load and heat produced. But, water alone will more efficiently cool than a 50/50. Coolant takes away from the waters efficiency.
So it sort of nulls that argument... at least to me.
I hope i articulated this well.
According to Redline:
* 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
I've made quite a few comments on WW in previous threads. I have no verifiable proof that it does do what is claimed, other than I've never had any heating/cooling issues, and it didn't do anything negative to the cooling system.
I can only assume the surfactants help. I've read enough documentation on the subject to conclude that it probably does.
