A seized or snapped glow plug takes the right tools and a steady hand to remove cleanly. That is exactly what we do. CR Auto Engineering removes broken and seized glow plugs at our Aston workshop, including repairing the cylinder head thread if it is needed, all in-house.
Glow plugs sit in the cylinder head of a diesel engine and pre-heat the combustion chamber so the engine starts cleanly when cold. Over years of heat cycling they corrode and seize into the head. When that happens, an ordinary service job turns into a difficult one.
The real risk is that the plug snaps during removal and leaves its tip stuck deep in the cylinder head. Getting it out from there without damaging the head or dropping debris into the cylinder takes a proper workshop and the right extraction tools. That is the difference between a quick job and an expensive one.
You may need this service if you have hard starting when cold, a glow plug warning light, misfiring or rough running on a cold morning, white smoke on start-up, or a failed glow plug flagged at a service that the garage could not remove.
Removing a snapped glow plug cleanly takes experience, the correct extraction tools, and somewhere to do the job properly. We have all three. We extract seized and broken plugs in our own workshop, and if the thread in the cylinder head has been damaged we can recut or insert a new thread rather than condemning the head.
Because we are engine specialists, we understand exactly what is happening inside the head while we work. That is the difference between getting your plug out and getting it out without creating a bigger problem.
When a glow plug snaps, we deal with it here, in our own workshop, rather than sending the head away.

A few of the things people ask most before booking a glow plug job in. If your question is not here, just call us.
We use specialist extraction tools to remove the broken section without damaging the cylinder head. This is exactly the kind of job we handle in-house.
In most cases, yes. We will always try the least invasive approach first and only escalate if the condition of the plug makes it necessary.
Often, yes. Failed previous attempts are a common reason people come to us. Call us and tell us what has been done so far.
A straightforward removal can be quick. A snapped plug with thread repair takes longer. We give you an honest estimate once we have assessed it.
