2012 how to save lots of money fast Wk2 v8 5.7l overheating – page 2 – jeep garage – jeep forum

My 2011 grand cherokee limited 5.7L hemi just started overheating while normal driving in outside how to save lots of money fast temps that are mild [70’s]. Running no air conditioning at the time the temps crept how to save lots of money fast up to 255. I reduced my speed immediately and the temps came back how to save lots of money fast down, but varied. When I got home and it had cooled overnight I how to save lots of money fast noticed the reservoir was not up to the fill level. I filled it to the full level with antifreeze [50/50 mix] and I took it to the jeep dealer and they how to save lots of money fast said the radiator has a hole and needs replaced and how to save lots of money fast while I am at it, I should also replace the thermostat as well. I am sad to say I don’t trust dealership service centers from past experience of them how to save lots of money fast trying to make me buy costly repairs on parts that how to save lots of money fast were not bad. I did not notice any leaks and drove it to how to save lots of money fast the dealership [had to shut if off 3 times to let it how to save lots of money fast cool down in order to get there without causing problems how to save lots of money fast from getting too hot; it got up to 257 at one point before I how to save lots of money fast was able to get pulled over and the engine shut how to save lots of money fast off. I ran it with the heater on and the fan how to save lots of money fast turned to the floor, but it did not blow hot air, just cool air through the vents] and when I checked the reservoir it still showed up how to save lots of money fast to the full mark. I already know of the T.I.P.M. Switch issues and thought this jeep had been all fixed how to save lots of money fast prior to my buying it. But, it has locked me out [when the keys are inside] I have locked the doors and returned to them being how to save lots of money fast unlocked, periodically the cruise control quits only to start working again how to save lots of money fast another day [or after being shut off and restarted] and the wipers quit working during a rain storm [to which the dealer said I needed a new motor] only to start working again days later all on their how to save lots of money fast own. I guess I am wondering if the overheating could possibly how to save lots of money fast have anything to do with the T.I.P.M.? I’ve had 4 grand cherokees all with the hemi motor how to save lots of money fast and never had problems like this jeep. I can certainly understand repairs are necessary on vehicles with how to save lots of money fast as many miles as I drive [this one has 118K] but I am sincerely hoping they don’t start just throwing parts at a problem at my how to save lots of money fast expense.

I can’t find a reference for the exact temp the electric how to save lots of money fast fan turns on, not even in the FSM manual. There appears to be some thermistor on the inside of how to save lots of money fast the fan shroud, that probably controls the fan, and from the looks of it, it probably isn’t calibrated to the nth degree. So the exact temp it turns on probably varies from how to save lots of money fast vehicle to vehicle, but likely within a few degrees for all. That might explain why they don’t publish an exact temp.

When moving, a good 10mph or more, under normal loads, AC off, seems to create enough airflow through the radiator the electric how to save lots of money fast fan is not needed. To avoid the fan running constantly, the turn on temp for the fan is higher than how to save lots of money fast the normal operating temp, but still well within a safe temp for the engine, once the water temp cools down to normal operating temp, the fan turns off again. Sitting still or driving slowly, like in a parking lot, will cause the temp to rise until the fan turns how to save lots of money fast on or you get moving fast enough to get enough how to save lots of money fast airflow through the radiator.

I suspect this is why they got rid of the how to save lots of money fast temp readout in the EVIC for the 2014 and on how to save lots of money fast WK2. Too many people complaining something was wrong when there wasn’t. Plenty of manufacturers have done this in the past with how to save lots of money fast gauges and readouts, when they got to many complaints from owners that didn’t understand how the system worked. I’m sure if dealerships didn’t tell people, "they all do that" when something is clearly wrong, more owners would trust dealerships when they tried to explain how to save lots of money fast what they are seeing is normal on the readout/gauge.
