How to replace the Head gaskets and timing chain assembly on a 2005 Jeep Grand Cherokee with the 4.7L V8.

Thank you for all the information. Well done video. Gives me more confidence to know that I can do it correctly. Thank you thank you thank you
Thank you so much for the kind works. Like many jobs it just takes a little patients and a bit of double checking to do correctly. Thanks for watching!
Nice job. I wish you can do the same in my 05 Grand cherokee limited, planning to change my timing chain also,
Very nice work 👍 thank you
Thank you so much for stopping by to check it out. Hope it helped you out.
Good work.
Thanks for stopping by to check it out.
Really good job explaining. If I could send you some dope & 🍺 I would. Really Good video by the way. Thanks.
lol Awesome!!! After this job some cold beer would be great! Thanks for watching!
Nice .
Thanks
You said that the passenger side cylinder head was hard to get off. Im having the same issue on mine howd you get the bolts out??
I had to get creative with a breaker bar and some extra leverage with a jack handle. Once they broke loose they came out no problem. Thought this one was a fluke with the stuck bolts. Let me know how you make out getting yours apart. Thanks for watching!
Only question..I’ve done the same thing you did keeping the chains on the sprocket except used rubber bands. Zip ties would be so much easier but how did you get them off once you had everything in place?
Once everything is in place, I just cut the zip tie. Thanks for watching and commenting.
ivw watched several teardown videos now of the 3.7 and 4.7 and i think now i have enough knowledge to finally redo the head gaskets on the liberty 3.7 happy you shared some tips and tricks for removing and putting them back on and the zip tie method of holding the chain is a great idea i do have 1 question we did just get the jeep liberty has about 190k on it do you need to replace the timing chains or is just a better idea to go ahead and do it anyway since your in there????
Glad i was able to fill in some blanks. It really is pretty straightforward. As for the chains, its a lot of work to get that far. I know the kit can be pricey but i would replace them if they have not yet if you plan to keep the car for a while longer. Also, make sure you replace the oil after all the work. A lot of debris gets into the pan.
You make it look easy! Hey, question; were the heads on that replaced previously by chance? They're awfully clean. Any indication the top end has been apart before?
Well, that's the idea, right. Make it easy. But really the scary part is just seeing all the stuff that needs to be removed first. I'm not exactly sure, but the heads did look rebuilt. They had a nice rattle can finish. lol
@@willpoweredgarage969 would a head gasket cause radiator fluid to boil?
And when replacing does the timing chains have to come off?
@@christopherlitton696 yes, if you have a failed head gasket, the compression is basically blowing by the broken piece of gasket and can go into the water jacket, thus creating bubbles in your cooling system. That's also fuel and air mixture from the intake that's going into your coolant too. The 4.7's are overhead cam engines, so the timing chain sprockets need to be removed. I just did one earlier this year. A bit of a learning curve but I was successful!
@@christopherlitton696 you said "boil". Yes, I've had failed head gaskets where the heat from the cylinder transfers into the coolant, and it can't cool it down quick enough. Keep in mind too, that the coolant system needs to be pressurized to raise the boiling point of coolant. It can't do that when a broken gasket is introducing cylinder gas into it. ALSO****I've had cracked cylinder heads from an overheating engine. The head gaskets were fine, but again, the cooling system wasn't sealed and oil even leaked through.....the cracks would expand the more I drove, thus the overheating symptom got progressively worse the hotter it got.
Nice video, do the exhaust manifolds stay with the head during head removal and installation ?
Yes, I left the manifolds attached. I did however have to replace a few broken bolts on them and it's easier with the heads off then in the truck.
@@willpoweredgarage969thanks
Out of curiosity, what part did you use for the timing cover gasket? Felpro TCS46003 or TCS46000? Which one would you go with? One of the parts come with RTV, is RTV a good idea or bad? I have a timing cover gasket that is leaking coolant.
I'm not sure what gasket I used. As for RTV, RTV is fine as long as it is not gobbed on. Too much will get into the engine and cause a whole lot of issues including clogging the oil pump pick up tube.
Very nice work can you please can you give me an approx price on this job please I'm doing and don't have idea PLEASE very helpful thank you
To replace the headgasket on one of these, the cost depends on your location and labor rate. But Id say a good estimate is between $1,300 and $1450.00. Hope this helps.
I mean the intake.
None of the valves were burnt.
That first exhaust valve is burnt
None of the valves were burnt, just a bad head gasket.
get a new on from orillies for 350.
New what?
