I already flushed about 10 times with laundry soap, and it now drains clear... but it seems to mysteriously still run warmer than before! It's a 11 month old Nissens radiator. I'm going to try removing it from the car, and soaking internally with purple degreaser as commonly done with Volvo intercoolers. I'll also be cleaning out a used mid-90s Volvo intercooler to install at the same time.

Any idea what those things weigh? I'd imagine the Pinz has lower gears and a vastly superior cooling system. I've come to the conclusion that the D24T Volvo cooling system is crappy for some reason, because it runs much hotter uphill yet makes much less horsepower than the Volvo red block engines in the same car. Maybe the red blocks flow water at a higher rate or something. Even with a brand new radiator, tropical fan clutch, new thermostat, and cast iron water pump I can hit 116C uphill with my D24T. A stock red block turbo making 50% more horsepower with a smaller radiator and a less efficient engine would never get over 100C under the same conditions. The same tropical fan clutch also kicks in at much lower temps on the red block despite the same thermostat opening temps, suggesting much better heat transfer to the radiator in the red block.
