I'll counter that with a Jeep a co-worker had at the wheel chair joint. I forget, it lasted "not very many miles." I'm thinking less that 60K and out of warranty. Dropped a couple of valve seats, dropped those valves and the engine was instant junk. Well, 1/4 of a second, anyway.
I disagree. Lol its just more of a pita to work on. The hp and torque numbers are right around the same as the 5.2 and 5.9 and they are fragile as glass.
Leave the bottom as is and add aluminum heads. Im not an engineer but ill sacrifice some weight for strength. I currently own 2 mag engines with 200k plus that still run like new. I've never personally seen a 4.7 make it past 100k without a rehaul. I've personally worked on two with less than 100k miles that were blew and probably seen 4 or more others with the same fate
Great engine. Bulletproof. But relatively poor mpg.
I had that same issue on a Dodge 3.5L. I replaced the timing belt and water pump, and it started to overheat a couple of days later. I took it back apart, and the plastic impeller on the water pump could spin on the shaft. I couldn't believe they wouldn't even pin it to the shaft.
It is off one of the first things I suggested when he bought it Yeh, LOL I know that onepull the plow off, I bet the overheating problem goes away.
Greenhorns. lol
Yeh I saw that. But the heater should not work well in that case.
I figured you did.
I don't know. I would think it would work like a **** if the water was not gettin pumped out of the engine very well.
Doesnt matter how hot the engine gets, if the coolant isn't being pumped through the heater core you'll have **** heat in the cabin.
I'll disagree because the system is under pressure. Water pump working or not, go cut a heater open when the engine is HOT and see what you get.
You haven't seen many 4.7's then! Haha
Pressure doesn't equal flow! See it often enough, it's my business!
If you say so!
I guess you're right my small sample size isn't big enough to draw a conclusion on the entire engine. But in my small sample size im not impressed. I've never owned one but I have worked on quite a few and they were all bad. Lol
Take the belts off your engine and see how good the heat is.......
I owned a 2004 Jeep with 4.7, they are probed to cracked heads. Mine had close to 200k the head repair was going to cost more than the worth of Jeep. I dumped Barsleak in radiator about every quarter and got another 30k out of it until I gave it away. It ran another3k after that until an electrical gremlin took it out. Andy
