The only way that a diesel engine will be able to fire off and run is by having a set of functional glow plugs. The glow plugs in a diesel engine perform a very specific job that is vital in the smooth running of the vehicle. When the car key is turned over, the glow plugs release an electrical spark that helps to start the combustion process. The timer that is on the diesel engine helps to ensure that the glow plugs fire at exactly the right time. Each time the key of the diesel engine is turned over, the glow plugs and timer will have to work.

Usually, the glow plugs on a diesel engine will last around 100,000 miles, but in some cases will wear out before then. The continuous use that these plugs get is a major factor in why they will usually burn out quickly. Due to the location of the glow plugs, it can be a bit difficult to check them. The timer on the diesel vehicle will usually not get a lot of attention until there are issues with it. It is your job to make sure that the issues with the glow plugs and timer are fixed in a hurry in order to reduce the amount of damage done to the diesel vehicle.

The internal components of an engine are put through the paces due to the heat that they are exposed. When the glow plugs and timer on a vehicle begin to wear out, you will usually have a fair amount of warning signs that you will notice. By taking notice of the warning signs that a vehicle gives, you will be able to get the glow plugs and timer fixed in a hurry. The following are some of the problems you may start to have when the glow plugs and timer on your vehicle are going bad:

  • The cylinders are having a problem with misfiring
  • An increase in the amount of smoke that is coming out of the tail pipe
  • The vehicle will start slowly or not start at all

Getting the issues with the glow plugs and time on a car will help to keep it reliable regardless of the conditions on the road. If you think you are having problems with your glow plugs and timer, have a certified mechanic replace your glow plugs and timer.
