Description
Disclaimer / Important Notice
This KIT is non-refundable and represents only one part of the repair. We do not provide any support for side effects of coolant leakage, coolant system faults, or improper installation. Support approved only for returning customers.
All KITS are validated and used daily within EVC Certified workshops under controlled conditions. We do not advise standalone installation outside of our network.
Coolant leaks typically cause additional damage beyond the motor itself, including software issues, cooling system contamination, and inverter overheating. Proper system recovery requires specific tools, procedures, and experience.
Installation requires a qualified technician with online ODIS (including SGW), proper flushing equipment, and HV experience. In most cases, improper installation leads to failure. If that happens, the vehicle will need to be sent to EV Clinic, and deploy will be charged separately.

⚠️ HIGH VOLTAGE SAFETY WARNING
DANGER: HIGH VOLTAGE ELECTRICAL SYSTEM
The Renault Zoe Q210 eDrive operates with potentially lethal high-voltage electrical energy. Incorrect handling, disassembly or repair can result in severe injury, electric shock or death.
Mandatory safety requirements:
- Installation and repair must be performed exclusively by qualified EV technicians with appropriate HV certification (HV Level 3 or equivalent, where applicable).
- Before disassembly, follow the manufacturer’s HV shutdown and isolation procedure, including disconnection of the LV service loop and 12V battery where specified.
- Verify the absence of voltage using approved, appropriately rated measuring equipment.
- Observe manufacturer-specified capacitor discharge times and secure the system against accidental re-energization.
- Use suitable PPE, insulated tools and approved HV workshop safety procedures.
Never assume that the high-voltage system is safe simply because the vehicle is switched off or the 12V battery is disconnected.
EV Clinic recommends installation exclusively by certified EV repair professionals.
