How to Retrofit Xsara Mist Jets to Your Rover 25 / MG ZR


This is a very popular modification in the Rover 25 / MG ZR community, quite simply you replace your standard washer jets with Citroen Xsara mist washer jets.

Instead of two focused streams from each washer jet, the Xsara mist jets do exactly what the name suggests, create a mist that covers majority of the screen, greatly improving the screen wiping and cleaning performance.



They're a straight swap with your original Rover / MG jets and should fit snugly in the cut out in the bonnet, without needing to modify the bonnet or the jet.

To remove the original jets you just need to pull the hose off from underneath the bonnet, compress the clip holding the jet to the bonnet and push it outwards.

Here's how mine look installed.

How to Check and Refill Rover 25 / MG ZR Screenwash


Locate the screenwash reservoir in the engine bay. It is in the left hand corner nearest to the front of the car. As standard it should have a windscreen and jet symbol on the top, as shown below.

If you can't see any fluid in the filler neck (like mine in the image below), I'd recommend topping up your screenwash. Sod's law you'll run out right when you need it most, better safe than sorry.

If you need to fill up, remove the screenwash filler cap and position it out of the way of the tube opening.

I'd highly recommend using a funnel to refill the washer fluid, it'll make the job a lot less messy. Anyone who's spilt screenwash in the engine bay will be familiar with the white residue it leaves behind when it's dried out, makes your engine bay look rather messy.

You can grab a funnel on Amazon dead cheap these days, even this fancy Draper one with removable gauze and detachable / flexible filler neck is only just over £5 delivered.



Place your funnel into the filler tube and pour in the washer fluid. Continue to fill up the reservoir until almost at the top of the tube.

If your reservoir is almost empty this may take some time, they are fairly large containers that stretch down behind the front bumper.

My Recommended Screenwash

In the past I'd just pick up any old premixed screenwash from the local supermarket, thinking it was dead cheap so it must be good value right?

Not quite... as soon as the temperature dipped below 0°C it'd freeze up, even when it wasn't frozen solid it wasn't that good at washing the screen, usually smearing the dirt evenly across the screen...



Ever since a friend recommended it, I've been using Autoglym Ultimate Screenwash. It ain't cheap granted, and it only comes in a 500ml bottle. However, being a concentrate, it dilutes to form up to 8 litres of screenwash, easily providing enough to fill the Rover 25 and MG ZR's 6.5 litre screenwash reservoir.

More importantly, I've never had it freeze up on me, and it clears the screen superbly with only a short jet, meaning you use less of it, win win! Oh, and unlike the cheap supermarket stuff, it actually smells nice too, you don't get that chemical smell in the cabin after spraying.



Job Done!

Only thing left to do is grab your keys and go for a drive!
