Hi, I have a 1998 Dodge Ram 1500 Van 318, do you know where the Engine Coolant Temperature Sensor is located. I think mine is bad and would like to try to replace it myself. Your knowledge in this matter would be greatly appreciated. Jeff

 

Welcome to DF! Will move this to the Ram Van section so you can get your answer.

 

It's in the top of the intake manifold next to the t-stat housing. Both are there, the 2-wire CTS and the 1-wire one for the dash gauge.

 

Thanks for the information, I will check it out!
