Water pump broke & cylinder decompressed? on 2004 Jeep Liberty

The water pump on my Jeep Liberty stopped working causing my battery light to come on. I kept driving, not knowing the water pump had stopped, then lost steering power, steam came out of the engine and the belt came off. They replaced the pump and now state that one of the cylinders has no compression and may have been caused by the engine overheating...is this right? The temperature guage never showed that the engine was hot, just the battery light came on... Help!

Your liberty has one serpentine belt that runs the water pump, alternator and power steering and thats why the battery light came on because the belt was not turning and it eventually burned through and the steam was cause by overheating because the water pump wasn't turning, probably blew the head gasket and that's why the one cylinder has no compression. the time to replace the one head gasket is 8.5 hrs and to replace both head gaskets is 9.9

Thanks very much Hemicuda, I appreciate the quick and thorough response. Does replacing these head gaskets require that the engine be torn down? and if the repair shop tells me I need to replace the entire engine, I should probably find another repair shop? What's a typical, approx cost for the head gasket replacement?

yes the top of the engine has to be dismantled and the cost runs $1235 to $1703 and depending on what they find when they dismantle the engine it might cost more, Does it run now?

The mechanic invited me to stop by last night so he could show me exactly what's going on with my Jeep, I appreciated this gesture. One of the cylinders on the right side of the engine is completely disfunctional/melted and needs to be replaced - I could even see that when I looked at the head?, laying on the floor in front of my Jeep. All cylinders on the left side seem to be functioning normally as will the new water pump as soon as the head? is replaced...For now the Jeep did not/does not run at all, but the mechanic didn't see anything else wrong and I'm hoping that once the new parts are installed it'll run better than before.

this isn't really a answer but i looking to see what could be wrong with my jeep and sense i like to work on it i never take it to the shop then i ran across how your jeep liberty broke and that is the same thing that my liberty is doing but you just saved me from going through what you went through. to get on to the point shouldn't have the temp. gauge have gone up because mine doesn't either so sense it doesn't read right shouldn't jeep pay for any damaged parts?

Hi Robert, so glad you caught your Jeep's problem before it progressed to the point that my jeep did, what a nightmare! I think Jeep should pay for the repair, since the gauge NEVER registered hot or anything but normal before the engine seized, but I'm completely doubtful that Chrysler or any other dealer, in the current economic crisis, would accept responsibility for this type of problem and then actually follow through and pay for it... Good luck with your Jeep!

Hey guys, I'm a backyard mechanic myself and have recently had coolant system issues with my 2004 Impala and learned why the temp gauge does not go up, but the hard way. The thermostat is designed to take temp reading FROM LIQUID ONLY. Once there is a leak that drains too much fluid, or steams out, or if there is an air pocket trapped around thermostat, then the stupid piece of crap WILL NOT READ THE TRUE TEMPERATURE OF ENGINE.!!!! Also, no car company will pay anything for that for multiple reasons they can state, like how the leak is what caused it and should have been caught then, routine maintenance, etc,etc. Totally sucks. But that's the answer. Thermostat doesn't read coolant temp unless actually submerged in coolant and the gauge that says temp u see on dash is not actually "engine temp" it is just " coolant temp"
