I had similar problems on my Æ97 T100. Mine would run fine until I started slowing down after running at highway speed then temp would creep up into the red and stay. After replacing cap, thermostat, water pump and fan clutch with no results û only thing left was the radiator which looked perfectly fine on the outside. I replaced it and all problems were cured.

Not sure what this boardÆs policy is on naming stores so IÆll say that I ordered one over the internet from a major internet radiator supplier in Jacksonville, Florida. It was brand new, all metal, lifetime guaranteed, well painted, û delivered to the house in 2 days for $170 total price including shipping. Somewhat surprisingly, it was an exact fit û all the bolt holes lined up, transmission lines fit perfectly, no installation problems at all. I have had no problems with it and donÆt mind recommending this place.
