can you use the spark plug removal tool from Lisle? Never had a glow plug break off but alot of 5.43v fords. It kinda drills in to the porsilen on a spark plug. maybe it would catch the glow plug as well.
Are the threads of the glow plug assembly broken off in the head? Any way to get a hold and turn? If so you can try to heat it with a torch or penetrating lubricant.
If there is no other solution but to drill and tap I would take off the head and take it to a cylinder shop, have it machined and replace the head. I know this may seem like a task but if you have time and another vehicle its a lot cheaper to do it yourself. Get a book for your vehicle that shows the repair and replace procedure and torque specks.
EDC LIGHT SOUND LIKE GLOW PLUGS NOT WORKING, COULD HAVE FAULTY GLOW PLUG RELAY OR ECM PROBLEMS.COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR.BEST TO LET GARAGE CODE SCAN FIRST DONT BUY NEW PARTS UNTIL SYSTEM CHECK OUT FIRST.
According to my Haynes Diesel Engine Repair manual this is a list of possible causes.
1.Slow idle incorrectly adjusted
2.Fast idle is inoperative
3.Restricted fuel return system
4.Glow plugs turn off too soon
5.Insufficient fuel suuply to injector pump
6.Injector pump malfunction
7.Incorrect, contaminated or poor quality fuel
8.Air in fuel.
The manual is part number 10330 anywhere they sell Haynes manuals ($20). It has a very good section on the 7.3 especially if you don't want to spend money at a diesel shop every time it needs work. Hope this helps.
Hi, If you plan on keeping the van with the 6.2 diesel, My recommendation would be to by a Haynes Manual for the 6.2 Gm Diesel engine. You have a glow plug controller, ( back where the distributor used to be ) a temp switch in the passenger side head, a couple of relays, and the glow plug themselves. The glow plus are along side each injector, about the size of a pencil with a wire hooked on the end. The injectors can be found by tracing the STEEL linens along side the valve covers.The Haynes Manual for the diesel gives a simple step by step guide to trouble shoot the glow plug system. A simple dc volt meter is all you need and a few tools.To copy that for you here would take many pages then you would have to print them out to take to the van. So hopefully you can afford to buy the manual. It will make your life way easier. I have owned 6 of those engines. I love em'. Wayne
THE BLOW PLUGS ARE UNDER THE VALVE COVER HOWEVER YOU CAN REMOVE THEM BY REMOVING THE GLOW PLUG HARNES FROM THE HEAD ( IT IS ON THE EXHAUST SIDE AND EACH GLOW PLUG HAD A "CONNECTOR THAT GOES THROUGHT THE HEAD ITS CIRCULAR ABOUT 1/2 - 3/4 INCH IN DIAMITER) AND REMOVE THE GLOW PLUG WITH A 10MM DEEP 1/4 INCH WITH AN EXTENSION
This is a Diesel van -- Glow plugs are not too terribly hard to replace, and as long as you disconnect the battery first when replacing them you shouldn't have a problem (except for maybe some access issues - It is a Van) - So yeah, if you can get to them - go for it - you won't hurt anything (Provided you do not cross thread anything) and you can always stop or put them back if you feel uncomforttable...Best of luck...
If the piece with all the tread's on it has screwed out then a punch will put it out if their are some of the tread's left on the piece broken in then you will have to bore it out. You will need to remove the cylinder head regardless as the piece stuck in when you remove it will fall into the cylinder and the only way to get it out it through the cylinder head.
please do not try and change yourself i tried and one broke off in the head it cost me 1900 dollars to rebuild the head
it broke because the aluminum head and the fine threads on the glowplugs fused together just take it in and let the garage be responsable if anything happends
