Glow Plug Testing
We test each glow plug to confirm it is heating properly and identify which cylinders have failed plugs. A single weak or dead glow plug can cause hard starting and a rough cold idle, so testing each one matters.

INSPECTION, DIAGNOSIS, AND REPAIR
What Glow Plug Service Includes at Matthews Currie Ford Pro Elite
Glow Plug Control & Relay Diagnosis
Many cold-start concerns trace back to the glow plug control module, relay, or wiring rather than the plugs themselves. We test the control circuit and the wait-to-start function so we do not replace good plugs by mistake.
Glow Plug Replacement
When a glow plug has failed, we remove and replace it with the correct part, to factory specifications. We replace plugs carefully and use quality components designed for your engine.
Seized or Broken Glow Plug Removal
On some diesel engines, glow plugs can seize or break during removal. When that happens, we use the appropriate methods to extract the plug and complete the job correctly.
Grid Heater Inspection
Some diesels use an intake air grid heater to aid cold starting instead of, or alongside, glow plugs. We can inspect and service this cold-start system as well.
Diagnostic Scan & Cold-Start Analysis
We scan for stored and pending codes, review live data, and confirm the cold-start system works as designed, so your diesel starts reliably when the temperature drops.

Glow Plug FAQs
Frequently Asked Questions
Glow plugs heat the combustion chambers in a diesel engine to help it start, especially in cold weather. They are different from spark plugs, since diesels ignite fuel with heat and compression rather than a spark.
Common signs include hard starting in cold weather, extended cranking, white smoke on a cold start, a rough idle until the engine warms up, and a glow plug or wait-to-start warning light.
The symptoms can overlap. We test the glow plugs, the control module or relay, and the wiring so the right part is replaced rather than guessing.
They mainly help with cold starting, though some systems continue to operate briefly after start for smoother running and emissions. Persistent cold-start trouble should be checked.
It varies by vehicle and how it is used. There is no single interval, so we test them and replace any that have failed based on their condition and your manufacturer's guidance.
On some diesel engines, glow plugs can seize or break during removal. We can extract a broken or stuck plug when needed.
Yes. Some diesels use an intake grid heater instead of, or along with, glow plugs. We service both cold-start systems. Call 941-477-1731 to confirm availability for your vehicle.
