So, as you have been trying to make us believe with your deceptive statements, are you willing to state clearly that "installing the 160F thermostat on an otherwise stock 996 will maintain coolant temperatures around 180F"? If so, please define "around". If around is within 25F of 180, then it may be a valid claim.

The fact is, just as LN states, this thermostat, just like the stock thermostat, works best with other mods, such as running the fans. What they do not state, is that running the fans wiith the stock thermostat will rpoduce the same results as will running the fans with your thermostat....and, it FREE. So to contnue to deceive members here and elsewhere that your thermostat will somehow produce results which are in conflict with the laws of physics is nothing short of bull****.

Let the back pedalling begin.

BTW: NO ONE here, but you, has ever stated that the thermostat maintains coolant temperatures aound 180F.

Im not defending anyone here. But this is the comment you started with and the comment you ended with.

Ok, I bought a porshe, I am not going to start crying about $$ now. You seem to be stuck on the $$ aspect of it. Im willing to try it even though its not FREE.

Free usually SUCKS

I have used 160 degree t-stats for many years on different cars, if the cooling system is capable it will keep the car that temp or close to it. Really it all depends on the ambient temp. So the Porsche cooling system is marginal since some models have or people add third radiators. The one thing that has not been brought up is that a 160 will give you constant flow because it will always be open. While the stock t-stat will be opening and closing to keep the car at that temp. So if steam pockets are a problem then the full flow of the 160 should help that. but that is just theory.

I agree with the above. Also, 160 degree is the point at which the thermostat opens, NOT at what temp the coolant remains. So yes, the coolant gauge may read higher than 160, but the gauge reading isn't that accurate anyway. This mod is one of those things that may work, but it's not going to hurt.

I have a Mustang with about 475-500 hp, it has a 160 thermostat.......but I don't think that where the HP is from, it combined with a huge aluminum radiator, a properly programmed electric fan, and a high flow water pump sure help to keep it cool though.

On a side note, my car has this thermostat installed, it runs fine.

Regardless of whether it is free or not, you have already been told it does not work so why would you even go through the effort. Even LN Engineering makes absolutely NO CLAIM that it will reduce your coolant temperatures

You're being had.

Pac996

Manufacturers of aircraft and cars generally set gauges up to be at the 4 main clock positions of 12, 3, 6 and 9 oclock. Modern aircraft always use the standard. So when you see your temp sitting at 12 oclock don't think it is above standard for the running temp of the car. The trick is for making scans easy to see if anything is out of specs and it works. Pilots not keeping a good scan going is what gets them behind the power curve on knowing whats going on. Now the guy who designed the 996 steering wheel is a different thing.......

I'll sum it up by stating that every engine that I produce includes the 160F thermostat. If the unit didn't work or was detrimental to the engine I'd not install it.

No complaints have been received about the performance of the units that we've sold, and we have them in service on five continents.

This is my question:

How many 996 owners change the coolant every 2 years?

I do it , and I can say that it's very important.
The coolant liquid wears and I can't understand why Porsche never changes it...

Get a third radiator. That will increase the flow and reduce temps because the center radiator has no AC evaporator in front of it.

chsu74

No one here mentioned cleaning your radiators first to improve airflow. This is a must as I saw my temp needle move from the right of the "O" to "8" after cleaning at speed. Idling will still creep the needle to "O."

gota911

.... or do what Phil did. Push the car out of the garage to the driveway, get in the car and make verbal VROOOM VROOOM noises. The engine in his C4S never over heated!

Sorry, but I hadn't had the opportunity to pick on Phil lately, so I couldn't pass up the chance to do so.

Cefalu

Did you install the 160 degree thermostat yet? I am curious about the results.

Shark Attack

No, I have a slight collant leak on a hose that comes off the water pump. I have to get a new hose. Then I have to get new coolant. I think I shoudl get to it this week.

Cefalu

OK, it will be interesting to see the data since I am thinking about the thermostat change as well. That genuine Porsche coolant isn't cheap. I just ordered it and it's $36/gal. It better not be 50/50.

Shark Attack

not really sure why we have to use the porsche stuff?
