I have a '95 F-150XLT, push-button 4x4, Auto hubs, 351 engine. This truck has 149,000 miles but runs very well. I want to invest in it and keep driving it indefinitely. So, I would like to identify and replace every sensor on the engine. Is a Ford dealer the best choice or is there a better after-market source? Thanks for your help.

 

If it's running well, I'd leave it alone until it gives you trouble. Almost anytime you try to fix something that isn't broke, you cause trouble.

 

i agree with chester. keep up with your normal maintenence ans she will be fine. dont want to go looking for more problems.

 

Buy a Haynes manual (PN 36058 ~$15) & a cheap digital multimeter ($8-30), and TEST as many sensors/actuators as you want. But don't remove or change any of them unless they TEST bad.



Then read the rest of the book. It tells you almost everything you need to know about maintaining & repairing that truck.
