How do i bleed the breaks on a 1999 Jeep Cherokee?

Answer 1

Answer

The 1988 jeep Cherokee Laredo has the sealed cooling system. Many bloggers have posted instructions on how to bleed or burp by removing the rad cap. This does not exist on the 88. Here is what I have come across during my search ( I am currently attempting to bleed my system), that you need to remove the temperature sensor valve. There is a bolt near the back of the valve cover under the hood on the driver's side. There is a small temperature fitting on top of the bolt that is easily pulled off. This is the sensor that feeds your dashboard gauge. When pulled off the temp will read zero. This procedure must be done after the car has cooled off, otherwise you will end up badly burned and needing to replace the bolt you just launched after being sprayed by boiling hot coolant. To start, be sure that the sensor bolt is higher than the front of the valve cover. In other words you need to lift the back of the car or park on a steep enough incline so that the back of the valve cover is higher than the front. When the bolt is removed you will hear air bubbles escape and hiss out as it leaves the hole. Immediately replace the bolt when coolant begins to flow. This process will need to be completed 5 or 6 times and will take most of the day because after each attempt you need to run the car to temperature and let cool before trying again. This will fix problems related to the Jeep running cooler than usual or over heating in heavy traffic. It will also fix the problem with your heater not blowing hot air. The bolt requires a 13m deep socket to be removed. It may also fix problems with leaking coolant.

What I did the other day was to Remove the upper radiator hose and finish filling the radiator that way. It can take forever trying to add through the coolant bottle and then it still will not take as much coolant as needed. Very frustrating, be nice to have a real radiator cap.

Answer 2

Open the bleeder valves if it is equipped. If not, then jack up the front of the car as high as possible, remove the radiator cap, fill the radiator with a 50/50 mix of antifreeze and distilled water to the top, start the engine, and let it run until no more air bubbles are escaping from the radiator. Keep the coolant level full while doing this.

Answer 3

If you are having an overheating problem check the thermostat and overflow tank pressure cap. There was a retrofit that included a lower pressuer relief cap for the overflow tank BUT the thermostat must also be changed to a lower temperature opening or the engine will overheat.

Answer 4

The cooling system on a 1989 Jeep Cherokee Laredo is bled by removing the radiator cap and squeezing the upper radiator hose. This causes the air to be pumped into the radiator and purging out the opening.

Answer 5

Make sure the parking brake is on hard.
Fill the brake fluid reservoir with DOT3 brake fluid.
Pump the brake pedal a few times and hold it down.
Have friend open the bleeder valve on the rt rear wheel. The pedal will go down, but holdit down till he closes the valve. Do it again and again until no air comes out.
Top off the reservoir again and repeat the bleeding procedure on the left rear caliper.
Top off the reservoir again and repeat the bleeding procedure on the
right front caliper.
Top off the reservoir again and repeat the bleeding procedure on the left front caliper BUT THIS TIME KEEP YOUR FOOT ON THE PEDAL AFTER HE CLOSES THE VALVE. Have him go to one of the rear calipers and bleed it ONLY one time. THIS BALANCES THE FRONT-TO-REAR PRESSURE.
After he closes the valve, pump the pedal and your brakes have been bled.
Top off the reservoir and you're done. Don't forget to release the parking brake before you drive away.
I highly recommend you invest $15 in a repair manual for your Jeep; most parts stores sell them. The instructions are in there in much better detail than I have just given you.

Answer 6

take the front grill off. the petcock is on the side of the radiator, passenger side.

Answer 7

Open the t/stat bleed valve or if there is a radiator petcock. run the engine while servicing as they are prone to air pockets in the cooling system.
