Windscreen washer pump access Evora S

[Spanky3]

My screenwash pump is barely pumping so I need to clean or replace it. Has anyone worked out how to access it on a post-MY12 Evora S?  I'm assuming the nearside oil cooler will block access through the arch and I don't fancy taking the bumper off...

Had to replace the screen wash level sensor on my gt430, as it did not like getting wet, caused the warning light to come on.

To access it, I was at SWLC, and helped, as it needed the under tray removed, (so I helped hold it up while all the bolts were undone). And similarly when fitting it back on.  Made it relatively easy as on a ramp.

They expected the various spacers to fall off, but luckily they had been fixed in position, otherwise they fall off and are different sizes - so causing confusion putting them in the correct places.

Looking at the parts diagram, it looks as if the pump is on the same side as the low fluid sensor. Sure some others must have done this.

You can pull the wheel, take th wheeel arch iner off, unbolt the oil cooler frame (if you have one) and gentle move it out of the way, then you need to unbolt the tank as its on the side of the tank against the chassis. Also make sure you get the rubber grommets. Dont know how much it is from lotus but as usual its off something random, I want to say either an mg or a blck cab, but cant remember as it was years ago now.

Thanks both for the tips.  Everything I've read so far was for early NAs without the cooler and the pumps on the outside of the tank.  I'll have a go at moving the cooler first and report back.  I'm hoping it's just a blocked non-return valve etc as the pump works but with a very low flow rate.

You’ve probably checked but on mine I found that the rubbish screen wash was due to the pipe being pinched by the access hatch.

re routed it to avoid the catches etc and it’s now fine.

My jets don’t work very well according to my last service it squeezes out a little water just about to clear the screen , I have no mechanical ability or equipment so be letting my lotus guys to quote me but I need window regulators & rear brakes sorted first at £1k 😱

Slightly delayed response but all sorted, thanks all for advice and ideas.

As 21gg said, once the arch liner is out the oil cooler unbolts to one side and ducting can be removed for access. The bottle is held in with four 8mm bolts, two of which are accessed through the front bumper inlet once the ducting is removed. A uj or wobble bar helps.

  I think the issue was the non return valve which I replaced with a 5mm straight connector.  Before I found it I snapped the pump outlet trying to wiggle the hose off so replaced the pump as well. It's from an MGF/MGTF.  All good now and squirting like never before.

While I was there I also found a weep from the IPS oil cooler. For once the eBay gods have smiled on me and I have just fitted a brand new cooler for 90 quid delivered instead of 700.
