I've been reading around some forum sites and have to ask it. Is replacing the ford thermostat with a cooler one have any advantage or disadvantage on motor performance, wear and tear, ect. I'm up in central Queensland so temps can get high especially in summer and we don't have the coolest of all nights either.

Whats your opinion?

Cheers Cameron

I've lived in the Pilbara for the last 8 years and it's pretty standard practise there to replace thermostat with an 82 degree one. Once I did that in my Landcruiser the temp gauge never moved whereas before it would move with varying ambient temps and degree of hard work that I was doing. Never had a problem with it afterwards.

When I had my edit done, Simon from Xtreme Ford Tuning did this too I believe and I noticed that my gauge sat lower again too. I would recommend calling him or any other reputable tuner and getting his point of view on this as it seems to be a good one.

I would say go ahead and do it but I'm no expert whatsoever. It should be easy enough to revert back to old thermostat if you needed to.

Just my opinion

Any other thoughts or ideas ??

Just what Rapid said, speak to a tuner as you will want to get the fans to come on sooner to offset the cooler thermostat.

In short it's something you do when you get a custom edit tune.

I live in Adelaide and am getting a custom tune donr this Friday 8/6/07 I spoke to my tuner re a cooler thermostat he reckons that it would be fine in summer but up more fuel consumption in winter as car will run a little richer. He suggested I leave it at this stage as I already have a 20% under drive and that should make run a wee bit cooler anyhow.

You want Power?

20% Performance Under Drives adds 9 rwkw for bugger all coin.

Theres not many N/A XR6 or XT owners on AFF without Under Drives and not one unhappy owner.

Its a must for the BA-BF N/A Inline 6 Cyl.

Take a look at the Under Drive theads here on this forum or try AFF for details.

can I run no thermostat or will I damage somthing?

yes u can run no stat but yes u will phuc sh*t up in summer and it will be stone cold in winter either situation not good

Do not run without a stat mate .. when you decide to get up it the coolant doesnt stay in the rad long enough to cool down + the motor will stay in rich warm up loop when cold HTH.

Go for a 82* if untuned or 71* with the fans brought in earlier via flashtune

71 is too cold and can lead to oil not working correctly, oil temp needs to be to a certain temperature for it's additives to work
