Rover 75 - Unblocking 75 drainage channels query

Hi

Both of my drainage channels (the one on the right when facing the car) were blocked and were filling up with water, so after work this evening I had a go at unblocking them.

Anyway, to be on the safe side, I removed the right hand plenum and water shield to check that the drainage channel there was OK and that water had not been filling up beneath the ECU.

All seemed nice and dry, however it was bunged up with leaves. Using a flexible Peugeot 106 aerial I had a go at unblocking, which appears successful (I now have a little pile of leaf mulch on the drive below where I was poking).

However I am a little concerned as there appeared to be no drainage tube in place under the hole as mentioned in the 75&ZT owners club PDF, poking through the hole felt as though I wass hitting metal, or is the drainage tube solid?

Also, I assume the ECU was OK being lifted up out of its mounting bracket to allow access to the hole (I was careful, but still worried)?

Finally - poking through that hole (the one below the ECU), I wouldn't have been hitting anything vital below the car like the exhaust or anything would I?

I have a 2002 model 2.0 V6.

I would really appreciate it if someone in the know could put my concerns to rest. As I've only had the car for mere days I just want to make sure I couldn't/wouldn't have broken anything.

Thanks
Chris

Lower drainage is just as you found it, poking through the channel will not cause any problem there is nothing breakable down there. ECU is meant to be lifted out to gain access so no problem there either. I have used a length of 15mm copper pipe to clear mine and it does appear to catch but needs a bit of a shove to get it through.
I'm sure you will be fine.

Thanks MM, that has made me feel a lot better. The fact that it was snagging and needed a bit more of a shove (though I was using a thinner rod than you) had me worried I might have knocked the drainage pipe out of place, punched a hole through it or worse, punched a hole through something more vital like the CAT.

I used a piece of broken garden cane to rod out the drain channel. With the aid of a torch, it is just possible to do it on the diesel without pulling out the ECU.

Question New owner smelling stale water!

Hello

I am a new owner of a 75 Con Auto 2003, and I am new to the forum.

When I enter the car and, particularly when I start the climate control - I can smell stale water as though it has got into something to do with the heater/cooler section.

Is that possible?

Is there anywhere that I can see pics of the location of the drainage tubes mentioned earlier?

Thanks for guidance from posts already read.

Geoff

You might have a wet pollen filter. There is a how to on the 75 club website regarding unblocking the drains, I did mine today. Well worth it.

Hi nobaxon and welcome

Have a read here about how to unblocking the drainage channels and also when your doing this you will see the pollen filter, I would check the drainage channels ASAP just to be on the safe side as it can cost loads if the ECU gets it wet.

If you need any help just start a new thread and someone will be along to help

How long are the drainage tubes (approx). I discovered one of mine was blocked and think I unblocked it with an old tooth brush, but I want to check if that has gone deep enough. Water seems to drain, just for reasurance really.

Hi..
I used a plumbers pipe bender..You know the springy steel thing they insert into copper pipes before bending them to stop the pipe from kinking..
On the right hand drain tube (as you face the engine) I suppose I pushed it into the tube about 12".
But the left CPU drain tube I pushed about 18" until I felt it clear the partial blockage in the drain tube..
To be honest I think for safety a toothbrush isn't long enough for the left (CPU) drain tube. I would use something longer.
Incidentally I never have to remove the CPU to clear my drain tube..If you shine a torch there is enough room to leave the CPU in place..Especially if you use a bendy rod like I do.
Hope this helps.

Simon

I tried to get access to the datasheet referred to by Kandyman but received the message "you are not authorised to view this page"

Any ideas?

I managed to get into the area of the ECU but couldn't see the centre drain tube and the ECU was not keen to move so I sort of ground to a halt, not wanting to possibly damage the ECU connectors.

Is the ECU supposed to be lifted vertically out please?
