We bought a 2005 Jeep Grand Cherokee Laredo 4x4 with 85,000 miles on it back in May 2012. This is my third Jeep, so I was very surprised when the heater core went out in September, taking out the water pump and thermostat with it. We replaced the water pump and thermostat, which cost us $500. The mechanic unhooked the heater core and said it wouldn't hurt to drive it that way since it was going to cost us another $300, and we couldn't afford it. We drove it home with no issue. The next day, Saturday, we went to a larger neighboring town 30 miles away. On the way home, it started billowing white smoke out of the tailpipe. We went straight home and parked it. We called the mechanic on Monday morning and explained what was going on. I asked if it could possibly be the gasket seals, as it was driving fine until the way home and it was only billowing white smoke. He said no, it had to be a cracked block and that it would be very costly to see if it was the seals due to all of the censors in the newer models. We live in a very small town and only have one mechanic who is GM certified, so isn't extremely familiar with Jeeps. I am wondering what your thoughts are on this. I guess I thought if the block was cracked it would be smoking darker, as it would be leaking coolant, oil, and gas. Will it hurt the engine worse if I drive it the 200 miles to where my parents live in the city, so someone who is used to working on newer Jeeps can look at it and give me an idea of what's wrong along with an estimate. Right now it has sat in the garage unused since September when it started smoking, and I'm making payments on a vehicle I can't drive because the mechanic hear scared my boyfriend in regard to what is wrong with the Jeep. I would greatly appreciate and advice you may have for me.
