Recovery Tank

To change coolant recovery reservoir, one must, then, remove the PCM without disconnecting the wiring harness. Use Hose Clamp Pliers (J 38185) to reposition the hose clamps, and then pull the hose away from the coolant recovery reserve. Next, extract the retaining nuts from the reservoir and remove the latter itself, draining all the coolant. For installation, the new coolant recovery reservoir must be installed with the retaining nuts torqued 8 - 11 Nm (6 - 8 ft. lbs.) while meticulously aligning themselves with the Fastener Notice in Service Precautions. Attach the hose to the reservoir, relocate the hose clamp with Hose Clamp Pliers (J 38185), and reinstall the PCM. Finally, top up with coolant in the reservoir.

In order to substitute the coolant recovery reserve, we first remove the Powertrain Control Module (PCM) without disconnecting the wiring harness. Next, use Hose Clamp Pliers (J 38185) to relocate the hose clamp and then pull the hose off the coolant recovery reservoir. That's next, remove the retaining nuts for the reservoir for coolant recovery and plug and pull out the reservoir itself, draining coolants out of it. Installation: Start by placing the new coolant recovery reservoir into position and tight by using retaining nuts to 8 - 11 Nm (6 - 8 ft. lbs). Reconnect the hose to the coolant recovery reservoir, relocate the hose clamp with the Hose Clamp Pliers (J38185), and replace Powertrain Control Module (PCM) back before topping off the reservoir with coolant.

Start replacement of the coolant recovery reservoir by uninstalling the PCM but leaving the wiring harness intact. Use Hose Clamp Pliers (J 38185) to move the hose clamp position then extract the hose from the coolant recovery reservoir. First, empty all coolant fluid from the reservoir by removing its retaining nuts and taking out the reservoir completely. Fasten the new coolant recovery reservoir into position with retaining nuts set to 8 - 11 Nm (6 - 8 ft. lbs.). Reposition the hose clamp with Hose Clamp Pliers (J 38185) then connect the hose to the reservoir before returning the PCM to its original position. The process concludes by adding coolant into the reservoir.

Begin coolant reservoir servicing after moving the VCM/PCM out of the way so it can rest safely without pulling wires. First disconnect the hose from the coolant recovery reservoir before you remove the retaining nuts and set the reservoir aside. Drain the reservoir's coolant contents following installation. Installation requires placing the coolant recovery reservoir into position followed by secure retention using 8 - 11 Nm (6 - 8 ft. lbs.) torque setting. Attach the hose to the coolant recovery reservoir followed by reinstalling the VCM/PCM and adding coolant to the reservoir before completion.

As a part of replacing your coolant recovery reservoir first remove your PCM without removing the wiring harness. Then, remove the hose from the coolant recovery reservoir and remove retaining nuts. Then, you need to remove the coolant recovery reservoir and drain the coolant out of it. Install it by inserting the new coolant recovery reservoir and make sure you tighten the retaining nuts to 8-11 Nm (6-8 ft. lbs.). Reconnect the hose to the engine coolant recovery reservoir, put the PCM back, and lastly, put some coolant in the reservoir.

Reconnect the hose.
