# Diesel Glow Plugs

Find glow plugs that match your engine and preheat system. Correct electrical and fitment specifications are essential for reliable starting.

Have the engine or equipment model and original part number ready. Our team can help with part identification and availability questions.

## Fit and equipment details

Glow plug type, voltage and installation dimensions must match the engine. Cold-start complaints can also involve a control module or electrical supply.

## Identify the correct Diesel Glow Plugs

Record engine year and model, plug specification and controller identification.

Include the engine model, mounting and electrical or coolant connections as relevant, plus the original component number. One engine family may have multiple accessory variants.

## Choosing the Right Replacement

Confirm physical length, electrical requirements and application before replacing individual plugs or a complete set.

Check physical mounting, configuration, power or cooling connection as applicable. DCT will confirm whether the specified accessory is currently available rather than infer fitment from the product family.
