Why Is Tesla Coolant Connector Removal So Difficult?
Tesla coolant hose fittings at the Power Conversion System (PCS) can be tightly secured, making the retaining clips difficult to release during removal. Before the fitting can be disconnected, the clips need to be spread wider than the barb on the PCS.
The challenge becomes greater when access around the fitting is limited. The technician needs to release the fitting clips while also pulling the hose fitting upward to disconnect it from the PCS.
This is where KA-5638 is designed to help. Instead of relying on improvised tools to access the fitting clips, KA-5638 is specifically shaped to engage and spread the clips, helping keep the fitting open during the removal process.
A Purpose-Built Solution for Tesla Coolant Connector Removal
KA-5638 is designed specifically for releasing the coolant hose fitting clips used at the Power Conversion System (PCS) on Tesla Model 3 and Model Y.
The tool simultaneously spreads the fitting clips wider than the PCS barb, allowing the fitting to be released while the tool and hose fitting are pulled upward together.
The design focuses on the actual removal procedure: spread the clips, keep the fitting open, and pull up to release.
