MIlking a radiator
My first Porsche and 928 was an '81 with 176,000 miles. When I changed the leaking radiator I noticed it was completely symetrical. I believe if you have one of these and "flip" the radiator around 120,000 miles, you will be rewarded with double the life expectancy because the failure cause is expansion by the hot coolant on the entry side of the radiator. The out flowing side looked great. For the $600 (memory slips) cost, I'd have certainly tried that had I known before it was leaking. For the record, I think if you plastic weld a leaking radiator, you are welding tired plastic and another failure is imminent. If you flip the welded radiator, you might improve your chances of extending life. I'd welcome feedback on your experiences.
