    My glow plugs keep cycling even after my engine has warmed to operating temp. What should I check first?

    Check your glow plug controller.

    I would check the temperature sensor first. I bought a new glow plug relay for $100 and found out that the $10 sensor was the problem.

    Where is that sensor, I am assuming it is in a waterjacket but which side of the engine. Is it buy the regular temp guage on the drivers side toward the front of the engine? Thanks for the help.

    I thought it was on the passenger side on the top back of the head.

    No, no it's in the passengers head next to the driver. Oh wait, that's my wife (sometimes she's a "temp sensor" as in either ice cold or tamale hot).
