We got a code when scanned thst says cylinder 8 glow plug control circuit and need to find out if we just need the plug or exactly what the deal is the check [engine](/topics-engine-chevy/) light came on but the truck is running Mechanic's Assistant: I don't remember all the details now but it was places to check for a loose connection. I found it and that fixed the problem. Does the light stay on, or does it blink? The check engine light stays in Let me also say it’s my sons truck, I’m a mom who really doesn’t know shit lol Mechanic's Assistant: What is the make/model/year of your car? Ok it’s 2007 Chevy Silverado diesal Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? Well that’s what we’re not sure of Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Depending on cost , we may want him to fix the cylinder 8 glow plug, if it’s expensive and something easy my son can do it

Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day. Normally a glow plug code is just a bad glow plug. Here are the replacement steps. [https://www.dropbox.com/s/9s90emk1c8vev5c/66GP8.pdf?dl=0](https://www.dropbox.com/s/9s90emk1c8vev5c/66GP8.pdf?dl=0) #8 is the cylinder closest to the firewall on the driver's side. To test and confirm the plug is to blame. You would unplug it and test the wire to it for DC voltage when the key is turned on. You want to see battery voltage. If not then let me know. If so then replace the glow plug to address this. They are $37 each from GM Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose

Hi I’m terri, I’m relaying this info to my son really quick if you can hang on
Automotive Expert
Not a problem, Terri

how much do you think it would cost to have someone else do the job
Automotive Expert
It is 1.2 hours of labor to replace one glow plug. Most dealer labor rates are $100-130 an hour.

Are you also a part of yourmechanic.com??? I was orig on that site and was gonna just have them come out tomorrow to look at it My son is no mechanic, he knows a little but I looked at the steps and it looks pretty hardScale of 1-10 for how difficult it is??? What do you think
Automotive Expert
No, I am not I would say it's about a 3 with 10 being the hardest. If he is not confident, then I would not suggest doing the job and possibly cause more damage.

Ok I think we will prob go that route then! I appreciate your helpIf I end up with more questions would I be able to speak to you again? During your working hours of courseActually I do have another question about the truck
Automotive Expert
