Any Guesses what this is ???

CSF radiators would be nice but I would be concerned about cleaning all bits and pieces out of the motor.

Do you think the motor is the issue? I was thinking if in the rads would be next to impossible to get out. Here is more history. No service records when I bought the car almost 2 years ago. Car got warm middle of 0 when ambient temps high but no coolant leak. This year I changed water pump, installed LN low temp stat, drained Dirty coolant somewhat dark and light green tint, No telling what was in there. Refilled with new Porsche (pink) coolant. Temps great when cool (on 180 hash mark) but still gets to right edge of 0 when 100 deg outside. I have drained about 2 gallons of coolant to pull cooler and reservoir. Thoughts? Thanks

Also this stuff was under the reservoir. Reservoir is dirty but no gel.

I have to defer you to an expert on how to flush the system, maybe JFP or Jake will chime-in.
I have an Air Lift system if you would like to borrow that. I think you are nearby, I am in Santa Maria.

I knew you were close by, I thought you were in SLO. We'll absolutely have to meet sometime. Thanks for the offer. I bought an Airlift when I changed the water pump.

I could use your expertise with the new Durametric I bought

AS I'm sure you've all figured out by now my Coolant reservoir finally crapped out. The pictures are of what I believe is the infamous gel that forms from mixing coolant. I found what you see under the reservoir when I pulled it out. There is no gel in the reservoir or the coolant I drained. Since this stuff forms when heated and the high point is the oil cooler, I am pulling the cooler to inspect for plugging from gel. Hopefully this should give me an indication of what to do next. I will use this excuse to upgrade to an S cooler at this time. Any thoughts or recommendations ARE appreciated. Thanks All.
