Thread: Redline WaterWetter - opinions for Rover V8

Yes agree . I fitted a Serck core to my 81 in Saudi in 1985. it was a tropical core with swirl inducers on the fins.

Looks like your new condenser is a problem. Maybe it is blocking airflow at high speed if your viscous comes on at 120Kmh, although I must say mine comes on at over 40C towing at 110 in my RRC 3.9.

I found in Saudi that the wind direction played a big part. Are you sure the wind was blowing in the same direction for both tests?

However your temps are pretty good on highway but in sand would be another issue.

Maybe you should try the waterwetter , because there is no better demo than in the ME.

With regard to the coolant, yes maybe try 30% as it rarely would get below -10C inland in winter.

I ended up fitting a mercedes 280 SE 16inch fan as well as the 10 inch on my condenser and that helped in sand particularly with a following wind.

Hi,

The condenser was built in the UK, to the design ambient of 45c with a very high RH, all the fins are copper, same as the the tubing which is HD. I've seen a marked improvement with A/C its not struggling as much. I left the ref charge the same, 1.14kgs, no point in over charging it. I've a second hand one, which has been plugged and ready to drop in if the need arrives.

Yes, agree the wind makes a huge effect, TBH i didn't take note in which way it was blowing, with the heat as is, i wont be in the sandy stuff around midday, late afternoon earlier evening no issues.

This evening it was showing 41c, and the engine temp on the SPA gauge was showing a steady 95c at 100ks, I've drained out 4 ltrs and filled with distilled water, should make the mixture around the 33/67, hopefully this should help.

Ive heard mixed reports about wetter water, saying it can block up the cores etc, is this correct?

Rgds,

Blocking cores???? Water wetter??? errrrrrr..... No.


I am not a moderator, I am a human being!!!

Water wetter is like a "surfectant" reducing surface tension and preventing cavitation bubble accumulation and hot spotting due to air pockets,.

Ok, i will try and get a bottle and see what it does.

Cheers

In high HP applications I've always used it. More on the fact it was recommended as a solution from someone who observed some issues one day and gave us a bottle to try. Instantly resolved the issues. I use it in daily applications as it sure can't hurt, and even less in the rover V8's with their potential for issues. If it can reduce hot spots (which seem to be possible causes of the liner issues where the head gaskets always fail in between common cylinders) then it can't be a bad thing. Temps seem to be more stable too.

I use it lately. Seems fine in my D2 V8. I replaced thermostat, pipes and fan clutch and did flush at 172,000 and the temps kept climbing...max of 108 one day so got a new OEM rad a few days ago and 98 max. Just added a TEFBA filter and (its not blocked no) max now 102 at idle, but straight back to 100 once thermos do their thing. I think it is just the filter element, so no problems with that. If I go hard core offroading I will probably just remove the filter element, but because it does not go past 102, I suspect it will be fine just to leave it there too.

Cheers

HI,

After lowering my concentrate to 28%, the engine temps have dropped down to around 92 in all conditions, so i'm happy, Iv'e a bottle of water wetter now, and that will be added at the weekend, if it helps i will be pleased

Rgds,
