At Squad Workshop, our recent project involved a Nissan Qashqai compressor and expansion valve replacement part of a complete air-conditioning overhaul to restore full cooling performance. The team carried out a bi-directional flush and replaced aged coolant hoses to ensure the new compressor performs reliably for years to come.
Nissan Qashqai J11 Compressor & Coolant Hose Replacement in Singapore
At Squad Workshop, we recently completed a full air-conditioning system overhaul on a Nissan Qashqai J11. The customer reported weak cooling performance and intermittent compressor engagement. Our diagnostics confirmed a failing A/C compressor and restricted expansion valve, which were both replaced with high-quality original parts.
To ensure long-term reliability, our technicians also replaced aged coolant hoses that showed signs of softening and leakage risk. We performed a bi-directional flushing process, effectively clearing contaminants from both the high and low sides of the system before refilling with fresh refrigerant and coolant.
This ensures maximum cooling efficiency, quieter operation, and longer compressor lifespan all backed by Squad Workshop’s quality workmanship and trusted service standards.
If your Nissan Qashqai’s air-con isn’t cooling well or you notice a refrigerant smell, it might be time to service your A/C system. Contact Squad Workshop, one of Singapore’s highest-rated specialist workshops, for diagnostics or repairs
A1: The compressor and expansion valve work hand-in-hand to regulate refrigerant pressure. Replacing both ensures balanced system performance and prevents premature failure of new components.
A2: A bi-directional flush cleans both the high and low sides of the A/C system. It removes debris and oil contaminants that could damage the new compressor or cause inefficient cooling.
A3: The entire process — including diagnostics, part replacement, flushing, and refilling — typically takes 3–4 hours.
A4: Common symptoms include weak cooling, rattling noises, fluctuating air-con temperature, or visible refrigerant leaks near the compressor.
A5: Yes. Warranty is provided when the full A/C system (compressor, expansion valve, cooling coil, and condenser) is replaced together for reliability assurance.
