You might solve 1 issue and cause two problems. Just like IMS issues is to Porsche cutting cost on engine head castings .

As a friendly reminder, re-read yourself on the heater core part. Heaters(cabin radiator) and engine are on a closed loop system. No thermostat in between. In the morning, you will feel heat at around 100F on the cluster.

The heater uses a small bypass from the engine, but when the thermostat opens, more warm water is in motion within the cooling system and the engine, heat comes up in greater amounts within the cabin; so the thermostat does affect how much and how soon you sense heat coming from the car.

And, regardless of what you do for a living, it is never a good idea to look down your nose at anyone.......................

Just an observation.

I've learned a ton from JFP and he has never steered me wrong. His experience with multiple Porsches over a long period of time has allowed him to see many, many more failure modes than any one of us will observe. The large sample size of cars he has been exposed too with & without low temp stats and with & without metal impeller pumps tells me his practical experience in this area carries more weight than the theoretical viewpoints.

One very real world piece of knowledge that JFP shared was to always use Porsche Brand MT fluid in the 6 speed. My thoughts were 'hell, gear oil is gear oil. It's all the same". Well I ignored JFP's advise, went with XXXXX brand and the shifting could only be described as s#itty. I drained it, put in the 'unicorn tears' oil from Porsche and it is 100% superb.

Like Jake Raby, JFP has seen it all. We would all do well to heed his advise when it is freely given.

JFP has provided much advice to this forum and others. In addition he has answered PM's from me when I first purchased my 986. I respect his knowledge and his generosity.
