This afternoon I was doing some preventive maintenance on my daughter's 1989 300TE. I replaced the thermostat and the two radiator hoses and I adjusted the anti-freeze/water ratio to about 40/60 (distilled water, of course).
I looked inside the upper radiator hose intake and...I am happy to report that the neck is reinforced with a metal sleeve.
Now I have a couple of questions
When did Behr start making radiator necks with the metal sleeve reinforcement?
Her car has 155K and I had planned on changing the radiator sometime this summer. I had assumed that her car still had the original radiator. But if the radiator is of recent vintage, then I may just leave it there one more year....
If the radiator has the metal reinforced neck, is it a safe bet to assume that it is NOT the original one?
Does anyone know the earliest date when Behr began reinforcing the neck?
Nothing in the car's previous records indicates a change of radiator.
I called he last PO and he didn't change the radiator. He had car from the end of 1996 to early 2002. So it could have been changed as recently as early 1996.
Any thoughts on this?
