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.
