Plenum Check - The Reason Why **ALL OWNERS PLEASE NOTE**

[hogweed]

Funny how some seem to get blocked and some don’t, isn’t it? My ECM was water damaged, so obviously had been flooded in the past – yet, in the 3 years I’ve owned it, the chamber’s remained bone dry, and no debris in it.

Cleaned it all out yesterday, I'm guessing it had never been done before, very clogged up, but all good now will get myself some of those guards soon.

Hi Members
Just an heads up keep an eye on those plenums with these down pours after the hot dry weather as lots of debris & dust may have made its way down into the plenum chamber combime the both with water and you get mud and that could be blocking the tube it only take a couple of minutes to check if you have the spy hole mods, happy rodding

OK, checked and it was thoroughly gunged! Now kicking myself for not doing this when I changed the pollen filter, the new one is now sporting a nice "tide mark".
Anyhow, I looked at doing the spyhole mod, but the lower ECU loom on my car sits neatly right smack on top of the plenum drain, so it's not even visible from above without pulling the ECU, let alone accessible. Of course it's "hardened" like that over the years and ain't changing its ways now....

Guess I'm stuck with wipers off et. all. and cursing the fool who thought those wiper mountings were a good idea (6 goes to get the N/S one "just so" today).

If you lift the ECU off it's brackets the wire can be pashed back a little and should stay where up bend it a little giving you access to the plenum tube in the future through the spy hold mod i have done a few which had the wiring loom crossing over the tube, good luck Arctic

Just to echo what's been said before...

I recently bought a 75 CDT with no service history. Got the car home, checked the plenum and there was 1/2" of water there. It took about 15 minutes to grind all of the composted **** out of the drain with a long screwdriver and then a pipe spring.

Always worth checking this out.

Took the grill off, but cant get any further because I cant seem to find my driver to get the screws out. But just a question, I checked my yellow tank (radiator one), and nothing was in there...yet I went to the garage 2 weeks ago and they fixed my coolant pipes leaks and added anti freeze too for 12 pounds..but it looked empty in the container???

And also, I went to fill my windscreen washer up because it was empty and I've dropped the freakin cap down the car and I cant seem to see it under the car. Is this dangerous without a cap? And also, I went to lock my car with central locking and it beeped (I know why it does this), but all the doors were closed and the bonnet was down....why is it telling me something is opened? Is it because theres no windscreen washer cap on?

To be honest, it does look pretty empty on the expansion tank, at the correct level.

Mine was like this, and was pointed out by Arctic to be too high :



But it should be like this



Not a brilliant picture, but it is sat just on the "max" mark.

Checked two members cars within two days and both have had at least 4" of water in the plenums, and have just about been saved from giving the ECU a good bath so do not delay in this weather check and check regular Arctic
