T350 cooling

[astonman]

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?

A manual override sounds very useful,has anyone got one fitted or know how to do it?

Anyone,any ideas on a manual override switch ?
