High performance coolant
Discussion
Had the Cerbera a couple of weeks now and loving it. If ever I need cheering up in the future when I have to dig deep into my wallet I just have to remember yesterday afternoon when my neighbours party guests all filed round to my drive and stood looking at the car and in the car. You can't help but feel some pride and what's even better is that there is no jealousy or muttered descriptions of "w*nk**" under their breath - just a shared enjoyment of everyones love for TVRs !
Anyway, onto my question. I would like to try and get the engine temperature down when I am crawling in traffic (it climbs and sits at 90). Is there a high performance coolant that anyone knows of that could help reduce this by a few centigrade or would I have to fit an upgraded fan ?

Had my neighbour stop me in the street to talk about the car today "i like your new TVR, love the color" ;-) Said i'll take him for a spin sometime.
As for coolant, well mine in traffic hits 100 and then quickly drops when the fan comes in. I think someone was saying on here the other day upto 105 is ok, but the handbook says 110c before worrying.
Also, those guages arent that accurate, if the fans are cutting in, should be fine. Correct me if I am wrong someone.

I've said it on here before, but I'll still say it again. 
I was concerned about my temps too, until I connected my ECU to a laptop. The ECU will report the correct temperatures, the guage won't necessarily.
IIRC the first fan is supposed to come on at 92C, the second at 95C, then switch off at 88C. My guage indicates about 105C when the 1st fan switches on.
As long as your fans are coming on, reducing temps then switching off again, I wouldn't worry.

Hold on! Water wetter (or indeed, any coolant) will NOT help reduce the temperature when stuck in traffic - there is simply a lack of airflow to dissipate the heat. The fans need to come on. Yours are doing this, so don't worry about it!
A water wetter might reduce the average temperate for a given airflow so you might use it if your radiator is marginal, but it won't help the traffic temperature - save your money.
