June 2022 - (At last) Added Rear Windscreen Washer
Got a generic windscreen washer pump, costed ₹ 200.00
Searched for rear
washer nozzles, but no one stocked any. All available was Maruti ones. Needed one with long neck and a right/acute angle trajectory. Bolero had a comparatively longer neck, while most of the others were flat/flush. Omni nozzle was available, but doubted fit in the tight space. Managed to get Bolero nozzle from a Mahindra pickup spare shop. No right angle, only jugaad will work. Would be replaced with OE nozzle.
Other pieces of hardware - 6 mm tube x 6 M and a couple of I-connectors.
Accessing the washer tank. Removed the RH headlamp and then the reservoir mouth. Can skip this, but gets more room to work around, especially with wiring and plumbing.
Then removed the RH fender liner.
Three 10-mm nuts and the tank is all yours.
Remove the connector and hose, or simply pull out the motor itself.
Hole for front motor and location for rear motor sits on RH and front respectively.
Tank part numbers for reference.
Spot the location.
Circular saw bit
and grinding bit
and you get the perfect hole.
Motor fits in perfectly without leak (tested).
Part 2 - plumbing. Searching for hole to get the tube inside the cabin.
Popped the smaller rubber grommet and there was a lot of room.
Removed the sill panels to draw the tubes to the rear, but ended up cleaning inside out.
The grommet hack.
The tricky part was getting the tube inside the boot lid.
Removing the spoiler.
Remove the high mounter stop light and two 10-mm nuts on either side.
Two more 10-mm nuts under there. Nozzle should sit here.
Two nuts each on either side.
Spoiler comes out.
Without the spoiler.
There is a small plastic lid covering (blocking) the nozzle on the spoiler. Just one screw to remove it.
Tube out at the end.
Drilled the hole
Installed the nozzle.
Installed motor and connected, but 6 M hose wasn't enough. Managed with a foot of petrol hose.
Last leg, the wiring
Stalk connections for reference.
After final adjustment
. OE nozzle is the way out. Let it be for the time being.
Backflow. This caused great delay in pumping, causing the wiper to run dry a cycle before it's fed.
Solution, check valve. Bought these from Boodmo for Estilo sometime back, but never installed. Bought 2 of them, so had one spare. Hyundai part - 98886-34000, shared with every Hyundai model sold here with rear wiper starting from the Santro to Santa Fe and the KIAs. Costs ₹ 95. Mahindra part was available at ₹24 on recent search.
Looks similar to normal connector.
Result - instant jet without reverse flow.
Rear washer in action. Stream looked weird, but checked with Beat OE and Santro and they both had similar flow. Switching to OE nozzle might improve a bit.
