Engine temperature

I have heard rumours of a porshe engine temp sensor that will fit the 1.8 16v and will regulate the temperature to a lower centigrade.......any advice/knowledge of this?

A lower opening temp (lower than 78 degrees) thermostat will help keep temps a bit lower and a lower temperature radiator fan switch would do much the same (in traffic anyway), but I wouldn't want to run a 16v lower than 100 deg on the oil and mid way on the water gauge anyway as they're most efficient there.

The 16v rad is pretty good at cooling, a 16v aircon/hot climates rad is bigger (635 instaead of 430mm) and so would give you more capacity for cooling if you ever needed it, unlikely on a standard 1.8 though.

There's a fan shroud for the 1.8 that has an extra blind built in, you might get one of those from an old passat, that doesn't require a different rad or fan, or you could fit a longer rad from a passat or aircon car (seen some on old Seat toledos) that have trwin fans too, they'll all fit in a 16v engine bay, it's just sourcing hoses may be a pain.

If you run a higher performance engine or do track days or something then a thermostatically controlled oil cooler (mocal etc plus sandwich plate to oil filter housing) would probably be a better investment .
