The red light on the coolant temperature gauge of my car occasionally (but in recent times more frequently) flashes slowly (0.5 Hz).
In a post dated 7/30/2018 Loren listed four conditions for the light to come on. The two conditions for which the light flashes slowly (0.5 Hz) are the following:
Engine coolant too low
Engine compartment temperature too high
None of these conditions applies to my car.
The light comes on after about 20 minutes of driving and it seems to be triggered (but not always) by running the engine above 4,500-5,000 RPM (with coolant temperature at normal values and, I assume, engine compartment temperature also at normal values. This is not driving in heavy traffic, this is normal out of town driving ).
Using the Porsche tester it was possible to establish that the engine compartment fan works. However, it does not come on when I drive the car in traffic and the coolant temperature gets to 215F. This, I would assume, should cause the engine compartment temperature to become elevated and the fan to run.
The engine compartment sensor, located on the passenger side intake manifold, is installed properly and seems to read the temperature of the engine compartment correctly.
Any thoughts on what is going on?
When I turn on the air conditioning, everything seems normal, the compressor appears to be working and the fan goes on, but only warm air comes out of the vents.
Where should I start to figure out what is wrong? I have Durametric , if that can help.
When we replaced the coolant in my car in 2013, we used coolant Porsche part number ‘000-043 -301-05-M100’(pre-mixed). The color, based on a little quantity left in one of the 2013 bottles, was red. The coolant in the car seems yellow now.
I have just topped off the coolant today, using Porsche coolant part number ‘000-043 -305 15’, red color (I mixed it with water, 50%).
Could somebody please confirm that the 2 coolants are compatible?
I'd appreciate a second set of eyes to verify these part numbers.

I'm least sure of the 3rd one but it looks like they simplified it for the Mk2 but didn't bother to update the Illustration because one end of this has 2 connections in the illustration but mine doesn't and the picture on Pelican Parts looks like mine, so I think I'm right.
Thanks for the help!

Greetings - I have traced a coolant leak to the rear of the alternator - wondering if anyone else has seen this and whether its repairable or I just have to commit to replacing it (once I can find a replacement - they seem to be rather hard to find at the moment).... Cheers.
