This Jeep Grand Cherokee Laredo with the 4.0l straight six engine came in. The driver said it needed a water pump and the thermostat had already been replaced. During the inspection we found that thermostat housing was leaking antifreeze all over the serpentine belt and the water pump and cooling fan was blowing engine coolant all over the engine compartment. Further inspection revealed that the thermostat housing bold was threaded between the thermostat housing and a metal heater core bypass hose that screws into the water pump. We removed the thermostat and housing and found orange RTV silicone sealant covering the thermostat gasket. The bench grinder with a wire wheel was used to restore the sealing surface of the thermostat housing and the thermostat was reinstalled with the radiator hoses and heater core hoses. During the test drive, the engine seemed to misfire and backfire. There is no check engine warning light on the dash.

Yeah amazing...I'm of the opinion that something this critical. Let a reputable shop do it. Chances are they will give some sort of guarantee/warranty so if they botch it it's on THEM but you do it cheaper and botch it it's on YOU. Spend a few extra bucks get it done right

The 4.0 Inline Six was one of the BEST engines ever made! A shop I worked at near MOAB Utah used to upgrade these engines with performance parts. These engines like to have their oil changed on a regular basis (every 3,000 miles) regardless of the type (regular or synthetic) and their coolant changed more frequently (every two years). Other than that they are fantastic engines (almost bullet proof)!

My working carrier has many years of repairing electronics. Mostly car radios and communications equipment. In my experience I learned that the customer rarely actually knew what the issue with their item was. Some even argued when the item repair was completed and returned to them. I have noticed the same thing in some of the videos you have put on your channel. I appreciate seeing a mechanic who understands what needs to be done and does the repair in a responsible and complete manner. I wish all were the same, but sadly that is not the case and you all get the bad rap because of it.

They were also used in Durangos right after the 3.9 V6 and 318 V8 got discontinued. (after 2001, most likely) If you have the 3.7, prepare to get another ECU. :(

@ralfie8801 6 месяцев назад

Check the plug wires Ray. They very well could be the originals and are deteriorated and saturated with anti-freeze which could make them arc to any metal they are routed close to. That condition could also be exacerbated by the spark plug gap being too wide.

Quality stuff, the same truck would warp the front rotors on long highway drives. The dealership couldn't find any problems and would throw a set of disks at it, free! Then I did some internet searches and found that this is a common problem with seized calipers that would drag on the disks and overheat them. The dealership was pretty grumpy. If buddy had waited just 3 more months, he would have had to pay for a set of calipers and disks instead of it being under warranty. It's a Jeep thing.

Thermostat problem not noticed - air bleed hole missing. The Jeep Service Manual (I have the 1996 edition, see pages 7-32 & 7-33.) states there should be a 1/16" to 3/32" air bleed hole in the flange of the thermostat on the 4.0L I6 and this hole should be at the top, 12 o'clock, position. A factory part was the hole, but aftermarket thermostats never do, so it must be drilled. If this isn't done, air is trapped in the head causing hot spots until the tstat opens.
