Two problems related to radiator have been reported for the 2000 Ford Ranger. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2000 Ford Ranger based on all problems reported for the 2000 Ranger.
The engine was 'not right' one day so the hood was opened in the bank parking lot and it appeared to be overheated. The temperature gage did not indicate this but the radiator was indeed without water. The radiator was filled and later checked out at the shop. It was determined that the temperature gage was not accurate and an external gage was added (a separate gage not part of the dashboard). The engine was never the same and has since needed to be replaced (with a remanufactured) due to being overheated. This was preventable if the temperature sensor had been operating properly. It was not broken (ie registered zero all the time), it was . . Bad or wrong sensor for the gage? don't know really. The vehicle had less than 90000 miles.
Both front shocks have leaked oil out, uneven tire wear, cracks inside bumper, headliner and other body joints shifting position, left radiator mount compressed badly. This is the second Ranger I have seen this on today.
