To remove the coolant pipes, start by disconnecting the battery's negative terminal and draining the cooling system. Remove the spare tire, jack, and jack storage bracket, as well as the mounting screws and plastic fasteners of the spare tire storage panel. Loosen the wheel nuts and hose clamp, and remove the coolant pipe bracket screw. Jack up the front of the vehicle, loosen the hose clamp, and remove the front and rear brackets from the coolant pipe. Remove the front wheel and swing the coolant pipe out from the rear, then work it out from between the front shock and lower A-arm. To install the new pipe, position it at the front and attach it to the water pump or thermostat housing hose. Attach the radiator inlet or outlet hose at the front compartment and install the mounting brackets underneath the vehicle. Install the front wheel, self-tapping screw, spare tire panel, jack storage bracket, jack, and spare tire. Finally, fill the cooling system, start the engine, and check for leaks. For the heater pipes, disconnect the battery cable and drain the coolant. Raise the vehicle and disconnect the heater hose at the water pump or the heater pipe on the underside of the intake manifold. Remove the appropriate hose clamp and bracket, as well as the main fuel tank support bracket and two smaller heater pipe brackets from the underside of the vehicle. To install the new pipe, place it in position and install the smaller heater pipe brackets and fuel tank main support bracket. Attach the pipe to the rubber hoses at both ends and install the bracket underneath the spare tire storage panel. Lower the vehicle, add coolant, start the engine, and check for leaks.
