1) temperature gauge pegs on HOT when simply turning the key on, about 6 sec.
2) cooling fans will not come on
3) after about 5 minutes “engine light" comes on
4) diagnostic indicator under drivers seat flashes every two seconds continuously; no pattern.
However, the engine is not running hot as long as I jump the fans and keep them running. I haven’t tried it without the fans running. I have checked it with a laser heat sensor on all areas such as thermostat housing, upper/lower radiator hoses, engine block, exhaust manifold, various small water hoses and it is well within specifications. One other item; there is another sensor next to the TW sensor which does not show in the shop manual, Chilton’s, or Haynes. It has a larger base nut than the TW sensor, it takes 22mm. No, haven't changed the thermosensor on the radiator, and it is running smoother than it ever has; go figure.
have the same problem?
