Good luck with that!! I won't ask what they charged ya' 'cause if ya' told me, I might grit my teeth and chip one. hehehe But just so you'll know, I replaced mine myself in about an hour and a half, and for less than $150.00 .

Luckily, I bought an extended warranty and am covered for 3 more years, or 30,000 miles, whichever comes first. It is running great now and I am getting ready to go to the DOGS.

Thanks again for all the help.

Darn, wish I had spotted this thread before today. . darn and bummer.

Question #1 .. WHY didn't the "Dealer" find the plugged radiator the FIRST time?????
Question #2 .. WHY did they change the water pump at all? Was it leaking?
Question #3 ..Are they going to reimburse you for these unnecessary repairs???

Being I've been doing this sort of stuff, professionally, for a long time, the only repair I can see that was necessary was the replacement of the Thermostat, due to the extended high-temperature operating of the engine, and as a matter of "preventive maintenance". It's very obvious if you have a coolant flow restriction, and the Factory Trained technicians should have followed a logical, well thought out, procedure in diagnosing the overheating issue, using the following steps. These are universal tests, that work on any style of cooling system.

Step 1. . Block test, to assure against damaged head gaskets and combustion gas contamination of the coolant. Personally, I get the engine cold, pop the coolant cap, use the 4-gas analyzer for tailpipes, then sniff the vapors in the coolant bottle for exhaust gasses. Anything over 5ppm of HC and the head gaskets get replaced.

Step 2. . okay, it passes the block test. Start the engine and monitor the temperature on a scanner plugged into the ALDL so YOU see what the PCM sees. Due to the "mixing bowl" thermostat style (bottom of the engine in front) on the 4.7, you will see a mild increase in engine temperature to about 195-200 degrees, then it will level off (not drop, like in a single-stat style) and the outlet hose will begin to get hot. This shows BOTH stages of the thermostat working properly, AND that you have good water pump flow because coolant is flowing through both sections of the dual-stage thermostat, as well as the hoses.

Okay, it passes the Block test, Thermostat checks good, and the Water pump is pumping water. Use a lazer/infrared temperature gun to isolate the temperature on the radiator. The section flowing water will be hotter than the section that is plugged, and there will be a gradual temperature gradient from inlet to outlet sides of the radiator. If there is any evidence of asymmetric temperatures, replace the radiator, simple as that. In extreme cases you can collapse the water pump inlet hose when you rev the engine to about 2500 rpm, because of the lack of flow through the radiator. It's very obvious. I mean. . hit you dead between the eyes obvious. . . .

So. .again I ask .. WHY were the unnecessary parts changed??? And, will the Dealer be reimbursing you for the unnecessary work that was performed, as well as the time you spent being bothered by their total ineptitude?

And, if it was all covered under warranty, do you dare ever take your vehicle back to them for any other repairs?? This is a simple little problem. . imagine if something tough cropped up.

I've seen too many . . . butchers .. . . who claim to be mechanics, botch this exact same problem over and over again. Sorry for the direct style of response, but it really irks me that this would take place at a dealership.

BEst of luck with the Truck. Hope it got fixed propelry. . . finally.

Thanks for jumping in Kris. (by the way, we missed you at The Nall)

All repairs were covered under warranty.

The water pump shaft was loose in it's bearing.

They should have found the blockage the first time.

Uh. . . . . . ."The water pump shaft was loose in it's bearing"

AHEM. . . . . . .AHEM. . . .AHEM. . . . . . .BU*&^%$T!!!!!!!!!!!!!!!!!!!

WP bearings have a .003-.005" interference PRESS fit when assembled. There is no way they can develop slop unless the bearings go bad, and yoiu would have heard it long before you would have been able to feel a bearing getting loose.

I am glad I do not know where this dealership is. . . the thought of paying them a visit and doing a lot of yelling is, for some reason. . extremely attractive at the moment.

Yeah, maybe next year I'll be back at the Nall. Sorry I missed out this year.

Ok... not saying your wrong...you're not. But hear me out on this one! I bought my dodge truck new in '92. In '92, I replaced a leaking water pump w/ bad bearing AND a radiator all because the sand casting hadn't been completely knocked out. When I slammed the gas to kick into passing gear, back pressure blew out the seams in my radiator and wiped the bearing...could have happened to him too...and I've only heard it happening to Dodges.

there is only one word to say with all this,,,,,,,,,DODGE.

[flyin woodbutcher]

this kind of crap happens all day, every day, all over the USA. Been there done that and have the shirt to prove it.
