Winter months are the hardest on our vehicles. From road salt to cold start-ups to gelled-up fuel systems, the end of every year marks the beginning of a long battle for diesels. With our '97 Ford F-350 once again back in Illinois for the winter, we decided to ensure that its 7.3L Power Stroke was prepared to perform flawlessly throughout the next five months of dismal weather conditions.

We took our truck over to Flynn's Shop in Alexander, Illinois, and got started by troubleshooting the truck's glow plug system. Then we replaced the glow plugs, valve cover gaskets, the under valve cover harnesses, and the glow plug relay. What we found was that after 14 years, we were overdue on this preventative maintenance project, and it only took us half a day to do everything. Keep in mind that the same basic diagnosis, tips, and tricks shown here apply to any diesel engine that utilizes a glow plug heating system.
