Default Excellent instructions

Thankyou for this - easy to follow instructions, and yes, the drain was full of gunk. Couldn't believe how much water came out! I suspected it might be blocked when I started getting water in the footwell. Mind you, there's been a LOT of rain recently. I bought the pipe bending spring from Screwfix, but instead of a bootlace and tube, I adapted a lambing aid I found in our local farm supplies shop, cut the Y piece off, rerouted the flex and it did the trick nicely. Thanks again!

The water/gunk/rubbish comes into the plenum from the right hand side as you look at the engine bay - top right - where the plenum guard sits in a U shaped section - many members put fish tank filter material here - snug under the bonnet strut to stop gunk/rubbish getting into the plenum

No, mine doesn't have a sunroof. I was actually referring to the ones above both wheelarches. In the meantime I actually put a bit of electrical tubing to replace both. Seems to do the job just fine.
Funny thing, after I sealed in the bits of tubing I found one of the original rubber drains underneath the side of the car, must have pushed it out from behind the wheel arch when putting the tubing.

Default Plenum clear out

Finally got around to clearing out the plenum drain tubes on my ZT mk2 at the weekend - what a state they were in!


A few observations from me.

1 - not sure the spyhole mod will work on the diesels, as one of the three cable bundles runs right in the line of sight between the hole and the drain tube. I'm thinking about using a length of plastic piping (drilled to allow drainage) to aid access from the spyhole.
2 - the drain hole beneath the servo can be clean from on top, rather than rummaging around in the undercarriage. I used a flexi aerial from my old 400, shoved that in the hole (blunted end first) and then slid the spiral pipe bender over the top. Job done!


I now have a very clean and shiny plenum, which hopefully will stay that way. I've taken a leaf (pun intended!) from my Mondeo and fitted aluminium mesh (Isopon) behing the grills as well as the fix everyone else is doing at the wiper mechanism end.



Another thing, which is a bit of an aside. Changed the pollen filter while I was in there as it looked like it hadn't been changed for about a decade. Miraculously today, the temperature gauge hit midway for the first time since I've owned her (Feb this year). It this a bit of a coincidence or could it be related? Wondered if the blocked filter could have been contributing somehow. I've got the new in-line thermostat from DMGRS to fit at some point to go belt & braces, so that job can be shelved until the spring.

You've still got to get underneath to trim the flat ends off the plenum drains if they have not already been done.

Also the temp gauge reads midscale between 74C and 116C by design.
I suspect your engine is running high 60's low 70's and stat well overdue a change.

Read about the dash diagnostics here and get an accurate engine temp reading.
It should reach 88C after 7 miles

Thanks Jules
My trip screen displays 'err' when the engine's running so doing diagnostics on the run might be a bit tricky. I can access the diagnostics when the engine isn't running, so maybe I can do a check after tonight's run home.


As for those pesky plenum tubes, that'll be a job for another day - too big to squeeze underneath and no axle stands at the mo!

IPK will still go into diagnostic mode even if ERR showing.

Sounds like it's had LSM module change without being programmed via T4.

We can cure that for you

You selling your services again Jules!
Bit of a trek for me to North Wales at the moment. Dealer I bought her off thought that was the case.

Owners travel from all over to see us.
This Belgium and Oslo were 2 last year !!

Most come from South East and South West as there don't seem to be any specialists in those areas.
