My T350t has always run at about 90ish degrees,not leaving much leeway.Both oil and water crept up to around 100 whilst backing into my garage after a spirited run,ok I know it's hot out there at the moment.But does anyone make a radiator that cools better than the standard one?or is it just an airflow thing?

You can upgrade the rad cooling fans, but to buy both is over £300, very expensive!

My tamora's water would barely rise above 85 in normal out of town driving and oil below 70. I've sold the car now and hopefully a T350 on the way. After driving the T350 the water was closer to 90 or above and oil above 80 in similar conditions. Pretty sure my rad was standard but the 350 fitted with a brand new alloy rad.
My C happily runs its water at 90C-ish. I was under the impression that since the cooling system is pressurised, temperatures of over 100C shouldn't cause much concern. My VX220T used to run mid-90s if I was exercising it/on a motorway run and I remember seeing the coolant temperature at 110C without much bother. I never had an issue with the Vauxhall and I sold it to a pal of mine, who's now taken the car to over 100k in mileage so those temperatures are manageable on Astra GSi engines - Trev Speed Sixes may be a different story!
In my uninformed opinion I would have thought that coolant at 90 degrees shouldn't really be an issue, particularly given that most cars run coolant at about 85C, plus with the warm weather we've had it's a potential cause of a bump of a few degrees in coolant temperature. If your coolant is reaching 90 within a few seconds of firing up the engine, then there's a problem. I remember an air leak in a friend's 3-series that would momentarily send the coolant gauge off the end of the scale, before settling down once the coolant bypassed the air leak.

The dash temperature sensor is lousy. Mine over read by 7 degrees, against the ecu sensor. Highly accurate electrical sensors cost big bucks. This isn't one of them.
May I correct you: The TVR sensor is lousy but has the price of a highly accurate one...so it combines the worst of both worlds :-)EvoOlli said:

Lol. I installed syvecs and dropped the fan activation temps by 5 degrees and have them set to come on almost together. Temperature never really goes beyond 93.
