After sorting out the wiring for the air-con system previously, I discovered my air-con condenser was punctured which caused it to be leaking. It presented a good chance to swap out to a bigger condenser and rework on the installation.
The new condenser is 23"x13" and 1/2" in thickness. Comparing to the old condenser on the left :). Be mindful of the size of the fittings for the hose when choosing your condenser. The cost of the condenser and fittings is about SGD$80 and is easily available.
Its properly secured to the chasis using nuts and bolts instead of cable-ties. The single 8" will be sufficient and there is enough space for a additional one, if the needs arise.
I managed to wire the radiator fan to operate when the compressor starts working for better cooling efficiency.
No more sweat during hot afternoon traffic jams!!
