If you decide to change the glow plugs:
With the engine "stone cold," disconnect battery, remove valve cover, disconnect glow plug connector, remove glow plug with a 10 mm deep socket, install new glow plug (torque to 13 ft.-lbs.), and reattach connector. After finishing the remaining 3 glow plugs on that bank, clean valve cover, install new gasket, and reinstall valve cover( torque to 97 in.-lbs.). Do the same thing for the other bank of glow plugs and reconnect battery. Not a difficult job--should take several hours.
. Use synthetic Mobil 1 Delvac 5W-40 HDEO. If you install a by-pass filter, many diesel engines can go 60,000 miles+ between changes, provided you get regular Used Oil Analysis (UOA) done. Synthetics make a big difference in diesels starting in cold weather.
. Add diesel fuel additive. In cold weather, many diesel owners have had problems with the new ultra low sulfur diesel fuel (ULSD). The problem comes during the refining process used to attain the ultra low sulfur ratio. That affects the naturally occurring wax in diesel in such a way that it can cause the fuel to turn from liquid to gel more readily in cold temperatures. Gelled fuel clogs the fuel filters and starves the engine, causing it to stop. Diesel fuel additives, such as Amsoil's, and ultraclean kerosene added to the fuel help prevent this problem.

. Purge any water from fuel system and change fuel filter regularly (every 15,000 miles).
. Install block heater.
