The guy at awesome (on the phone) said this screws directly into the radiator?

correct me if im wrong, but surely this is for the fan connector.....

or does any one have a 3 pole terminal on there radiator on their MK3?

i was interested in fitting this, as it kicks the fan in at around 80oC, helping to keep the overall temp down........

why do you want temp to keep at 80? Do you do track days often? If not the replace it with a standard item.

Also that one is for a 1.8T as it has a different configuration of the contacts as to that of a mk3.

i drive 76 miles every day to my work, often at 80-100 mph, then as i enter Edinburgh, spend alot of time sitting in traffic idling....

ive just had to replace the fan in my car, and my car gets red hot, so, yeah track days everyday really....

and i wasnt sure if it was even for the MK3, as i couldnt see where to fit it?..... but its under the MK3 SECTION, in awesome's site""!!


would just changin the thermostat for a lower temp one be the answer?

I think you have a problem, I would start with seeing if you have a airlock.

Agree with wayne. You have a problem. The fan switch itself wouldn't be the answer either, you would need a lower temp thermostat as well.

It's not hotter than normal, there is no fault!!!

I was just interested in lowering the temprature of the car, trying to prolong it's life and make it more efficient during the hot summers is all..... I had to change the fan because I ran a deer over (forgot to mention, replaced the radiator, but the fan was catching on the cowling and eventually burnt out)

The problem is with running cooler thermostats etc is that some times they can trick the ecu into running the cold map all the time and you then end using loads of fuel.

Exactly, unless you're running a huge stinking hot turbo conversion where maximum cooling is paramount i wouldn't bother swapping from a standard unit.

Agree with both of the above comments.

Got this from another forum

There is not just one "best" temperature - it depends on how the engine was built and where you are measuring the coolant temperature: at the head or the intake manifold? For a street car you will experience the best oil life and engine longentivity when your coolant is 200 to 205 degrees. Oil life is shorter when the engine is run cooler because there needs to be a sufficient engine temperature to burn off the atmospheric contaminants that are attracted to oil - oil is hydroscopic.
