Default Thermostat Options for 3ltr V6

Hi All,

RE: 3ltr V6 cooling

Does anyone run a cooler thermostat than the standard 89 degree ? is there any benefit of running these engines cooler? Should I stay standard 89 degree, or with high flow or go cooler?

I also have a weekend / track car (E30 BMW 6 Cyl - notorious for head cracks too BTW) where I run a 71 degree thermostat instead of the 80 degree and this head has held together for over 10 years !

Any options or advice would be appreciated.

Cheers

SWBASS

The designers, in their wisdom, opted for a certain temperature for the thermostat to start opening. Whilst I can see why you want to run a cooler thermostat, unless there has been a history of cracked heads, I would stick with original design. If you run cooler, the ECU will probably not optimise the fuel mixtures properly.

And running your engine too cool can add to wear.

If you are trying to run cooler due to an overheating problem, you have an issue with the cooling system to resolve.
