I`ve read about and now experienced the reluctance of the C2 996 to warm up. My car has 50kkm, and it seems in 25 degree ambient, to take about 15miles for the gearchange and the low speed response to come smooth.
Is this universal with the 996 C2...or just some cars ?
cheers

 

I don't know if it's universal, but when it's cold here, which is not often, it takes my car a long time to reach 180*. So I would say it's normal.

 

Out here on the left coast, it takes mine about 15 minutes to reach 180*. Longer on really cold days which, like FLA996TT, isn't very often.

 

On a 30-ish degree day, seems like it's a good 15 minutes to get up to 180 degrees. It may be my imagination, but since I went to a 160 degree thermostat it seems like it takes a little longer than it used to, and the car runs a little cooler.

 

who is the best vendor for the 160 degree stat?

Of course it takes longer with the 160... The thermostat opens at 160 instead of 180. All that does is delay the time it takes the engine to get to its designed operating temperature. I am not being critical of those using the 160,,,,, but, I don't understand why they do.

 

As was explained by others: "

Depending upon the ambient conditions, with a 160F stat in your M96 and in “steady state” driving (open road, constant speed); you will be running in the mid 170’s to perhaps low 180’s, so your concerns about it being too cool are unfounded. Remember that the stat controls the minimum operating temperature, thereby lowering the steady state temp. With the 160 stat in place, in heavy traffic you will still heat up enough for the fans to kick in, but when you get moving again the temp will drop back to a lower steady state condition. Two things to also consider; Porsche uses a 160 stat in some their high end engines from the factory, and your OEM stat starts to open in the low 180’s, but is not fully open until well over 200F (the dash gauges in these cars are both inaccurate and non-linear), and you are probably running in the 210F and up range at steady state currently.

That would be LN Engineering

 

Being new to the 996, just curious, does everybody's oil pressure stay pegged at 5 for a good while when cold?

 

Yes this is exactly how it should operate.

 

Mine does too. If its not pegged at 5, then you have a problem.
also we take a lot longer to warm up due to having 9 QTS of oil in our dry sump!
Cheers

 

Thanks guys, for the responses. That makes all the sense in the world.

 

While our 996s may take longer to warm up and do have 9 qts of oil our engines are not a dry sump system. Only the GT3s and turbos are dry sump engines.

 

Oh no... Thats my bad! 9 QTS in our oil pan !
Thx @Bornrich for the update... i Truly thought we had a dry sump system... oh well time to sell the car now lol
