Just bought a 2006 Dodge Ram 1500 4dr Quad Cab 140.5 SLT with 88,000 miles on it.
Test drive went smooth, no issues but I didn't really put it through its paces. Bought it, as is. On the ride home, temp started to spike, pulled over and there was brand new coolant in the reservoir. Got the truck home, by watching temp and pulling over when necessary. Opened the radiator the next day, and it took about 1.5 gallons of antifreeze. After getting all the air out of the system, the truck was running fine. Drove about 50 miles, no issues.
The following day i got 2 "P0300 Random/Multiple Cylinder Misfire"
So I figured a tune up wouldn't hurt to start with. Air filter, Spark Plugs, Ignition Coils, Oil, & filter
While removing the ignition coils, I broke 2 of the bolts for the coils. I got everything out but I can't find the replacement bolts online. I think I'm not using the correct terminology. I've searched "Ignition coil mounting bolt" "Ignition coil bolt" "Intake manifold bolt" and many more variations of this with no luck.
While pulling the existing spark plugs, one broke off in the head. (Front driver side cylinder) All the other plugs looked decent, one or two were very corroded. It broke off clean at the threads. I've never had this happen before and I'm not new to maintaining vehicles. Looking at videos online, I guess I'll try an ez out first. My concern with this is that the plug is so corroded/seized that I couldn't break it free with a 3/8 ratchet with a long handle (probably why I broke it off in the first place, I know. But this plug is so tight). Can an ez out get a good enough bite that I can really put some torque on this plug? I've read that ez outs break pretty easily and that will only complicate my problem.
In short what I'm asking is the following.

1) There are no obvious leaks after refilling coolant. However, coolant levels have dropped. Where would the coolant have gone when the previous owner had the truck? (FYI No coolant in oil, truck doesn't blow smoke out exhaust, not leaking on driveway)

2) Where can I find replacement Ignition coil bolts

2) Direction on removing this broken spark plug.

3) This is my first dodge, any info on this generation to help getting and keeping this truck running would be nice. I know every car has it's common issues, some insight on this would be nice as well.
I just had a baby so i don't have time to scour the forum/internet for this info. Any insight is greatly appreciated. Attached are photos.

 

The trouble is, if you break the easy-out, and they are a LOT harder than a sparkplug, and also more brittle.... You have a serious problem, and will probably have to pull the head..... With the head off, getting everything out is easy, but, makes for a rather expensive tune up.... So, get the largest easy-out that will fit the hole ya got, stick it in there, and apply pressure. Do NOT jerk on it. That WILL break it. Just apply pressure, increasing as you have to. It will either work, or it won't.... and you will still have to pull the head.

For the bolts, get a part number from the dealer, then just do a google search on the part number, several sources should come up.

Can you pressure test the cooling system??

 

Might want to spray a shot of liquid wrench and let it soak in before you start. On an unknown vehicle, I usually do this, as well as screw then out and back in a little, increasing as I go along. Some disagree but I always add anti seize when installing plugs.

 

I would shoot PB Blaster on the spark plug and fill it up. Let it sit for a couple of days to let it soak in and then try the easy out trick. Your only other option is pull the head after that.
the loss of coolant could be that the head gasket is about to go. It may not be going in the motor but actually going into the combustion chamber after the truck gets hot and burning off. I had an old Toyota do the same thing. I finally figured it out by running the truck and getting it hot and holding a piece of cardboard to the exhaust to see how wet it got. Sure enough with in a couple of minutes it was wet. I pulled the head and could see the gasket was just cracked enough that when it got hot it would seep into the combustion chamber and burn into the exhaust. Changed the head gasket and never had a problem after that.
as far as the coil bolts. Bolts are bolts. All they do is hold the coil in place so it doesn’t come loose. Go down to lowes or Home Depot with one of the other good bolts and get one that will match up. It will make no difference

 

1. Coolant leak. Either you didn't get all of the air out during the initial fill, or, you're missing a leak. You can get an inexpensive black light that will make coolant leaks obvious. Clean up any coolant on your engine then check again later for leaks.
2. I think this is the part number for the bolt you are holding: 06509136AA
3. There are multiple ways to remove a broken spark plug and all of them have about a 50 percent success rate. I like heyyou's suggestion of large easy out. Don't put much force on it because you have already pulled out the electrode and any bits will go onto the piston head.

You need to know what cylinders are mis-firing, that is where you'll find the problem. Your truck will display codes in the odometer when you cycle the key three times from off to on, then leave in on position.
I suspect the truck has had some overheats and possible head gasket leak. Try removing the radiator cap with engine cold, then start it up with the cap off and let engine come to temp. If you are getting bubbles out of the radiator filler neck then head gasket is bad.
Is that autolite the right plug for your truck? I think some of the problem here is poor maintenance, and maybe improper use of an impact gun.

 

So after letting penitrating oil soak for a few days. I tried to use a #5 Spiral EZOUT with no sucess. Everytime i got a good bite on the plug, the #5 Spiral EZOUT would just slip off. I then added more penitrating oil and continued research. I found a great website that explained spiral EZOuts generally don't work. They suggested using a square EZOUT and it did the trick. Then i vaccumed out the cylinder and finished installing new plugs and ignition coils.

Went and started up the truck after my triumphant extraction of the broken plug. I now have 7 Error codes....(Keep in mind i started this because i had 1 code)

Codes include the following (I am new to using code readers FYI- i have OBDII/EOBD from walmart)
1/7: P0300 $07E8 Random/Multiple Cylider Misfire
2/7: P0308 $07E8 Cylinder 8 Misfire
3/7: P2323 $07E8 Ignition coil H Secondary Circut
4/7: P0113 $07E8 Intake air temp. sensor 1 Circut high
5/7: P0300 $07E8Pd Random/Multiple Cylider Misfire
6/7: P0308 $07E8Pd Cylinder 8 Misfire
7/7: P2323 $07E8Pd Ignition coil H Secondary Circut

I am fairly positive i didnt screw up installing the plugs or coils. Any help here would be nice. Please & Thank you!

 

The parts you installed are causing problems.
What plugs did you put in? Any rare earth plug can cause codes.
What is brand of coils you installed? Do you still have the old coils?
That half plug you extracted was cross-threaded and I suspect the threads in the head are damaged. What cylinder was that?

 

Cylinder 2 had the broken plug. Once i got it out, i scoped the cylinder with a camera to look for porcelain (There was some, I vacuumed it out) and the cylinder looked rusty. Could it have been from all the rust penetrator i used? I literally put an entire can on it throughout the week.

I do have the old coils but most of them broke while removing them. I tried installing a good old one on the #8 cylinder to see if that would help and it did not.

I installed plugs and coils:
CarQuest Ignition Coils EBC1343
Denso Iridium Plugs IK16TT 4701

 

Iridium plugs have caused codes many times. I rec switch to copper plugs.

 

I'll try that, thanks. Any recommendations on plug, coils, and oil??
