Hi, iv got a 1.8 8v mk1 rsi that i only picked up the other day. The car is mint and not long ago had a full engine rebuild. Since i'v had it iv noticed the temprature seems to gradually creep up past the usual midway mark on the gauge, When i asked my friend i bought it from he said its always done that and his williams done the same till he fitted a second radiator to it so my question is is this a common problenm with these engines/cars and if so should i look into uprating the cooling system with a new radiator or a second radiator??? :S all help much appreciated
