I just picked up a 94 2.5L with 116,000 on the odometer. Everything seems to run fine except the temp guage doesn't appear to be reading correctly. The guy who sold it to me (local reputable smog shop owner) said that he installed an aftermarket temp guage and that it is reading fine. I've only driven it for a day or so and for a total of about 20 miles. Under the hood where the sensor is installed has an odd brass t-joint for the sensor in the block and I am concerned that this is the reason it may not be reading right.
If this picture is alarming or unusual, what would you guys recommend?
Any help is appreciated.
