You are one of the unlucky ones like myself who got a car that runs hot.

There are a few people on here who will say that it is impossible that your car is running hot just because theirs is not running hot, so you must be street racing or driving too fast... Each cast motor is going to have variances some may have had their cooling channels cleaned out better than others. Its a man made mass produced product and there will be differences from engine block to engine block.

This is my Z there are many like it but this one is mine.

Time for an oilcooler... Buy a quality kit from GTM or Z1 and you will be happy and not worry about oil temps again...
