CR Cold Weather Inspection intercooler icing

[dweisel]

Just wanted to give all CR owners a heads up with cold weather fast approaching. Some CR owners including myself have found water and oily goo in their cold side inter cooler hoses. Its usually not a problem if there isn't much there. At times though this water can build up enough that when it freezes it can casue a no start problem. The inspection of the cold side inter cooler hose is quite easy. First remove the plastic belly pan. After the pan is off look on the right side of the engine from below. You will see a rubber hose approx. 2 inches in diameter. This is the cold side inter cooler hose. On one end of the hose you will see a regular hose clamp. On the other end is a band type clamp. The end with the regular hose clamp is the end you want to take loose. This end connect to a plastic duct. Loosen the clamp enough to slide it back on the hose out of the way. Now work the hose off the plactic duct. It may take a little effort as it does fit tightly. As soon as you get the hose started off you may get some water from the hose. Pull the hose completely off the duct. This will let you drain all the water(if any) There may also be some oily goo. This goo is from normal oil and water/dirt mixing together in the hose.The color of this goo can range from dark gray to tan. Various amounts of water have been found by owners. On my 09 JSW I removed approx. 1-1/2 to 2 cups. On my 09 Sedan the water was minimal. I checked my neighbors 09 Sedan and the water was also minimal in her inner cooler hose.

Here are a few pics of what you may or may not find.

Yuck! Why is there so much condensation in there? I always wear gloves when handling chemicals like oil and such. That looks pretty nasty.

Also, for anyone who does remove the hose, make sure that it's clipped on properly or else it can pop off later when you're driving and cause a running problem.

Chitty, I don't think that much water was caused by condensation in the inner cooler. Our JSW was run in 10 hours of steady hard rain. My thoughts are the water could have been pulled in through the upper hose clamp by a difference in the pressure between the outside and inside air. Other people have found this same water in their inner cooler hoses. Some have found even more than what I did. One case I know of the entire hose was blocked off with solid ice and caused a no start problem. IIRC, there was someone else who's hose had enough water in it that it was injested into the engine. So, I feel its a good thing to keep a check on periodically,especially in wet conditions. The oily goo looks nastier than it really is. I hope other members check their cold side inner cooler hose and report back their findings.

James I'm sure you have followed the latest "2009 Jetta major engine failure. Your thought please." Thread over at the place that banned you. I'm sure if you where to speak to the Mods you may be able to get this info transfered over there.

I'm not really interested in going back and posting on the tdiclub anymore. Too much censorship by the mods and its not worth the hassle. As far as the thread you are asking about. I can't view the tdiclub anymore even as a guest. They are pretty throrough at blocking ALL my devices. Home pc,laptop and phone.

They just have my ISP addresses blocked. I could use another device if I really wanted to view the forum. My ban at tdiclub will be lifted at 2am 01/02/2011. I'll probably check in and see whats going on,but I doubt I'll start any threads or post anymore. Of course ''Never say never'' so, I won't say I'd never post there again.

Thanks Chitty,its way different here. Now back on topic. CR owners please check your cold side inner cooler hose. I think its a good preventive maintenance thing to do for anyone running in cold wet weather.

Thanks dweisel, good to see you have found a new place to post your information.

Chitty, perhaps you could expand on dweisel's description of checking the inter cooler hose and put it in the "how to" section of your website. Just a thought...

BTW, your "how to" section is awesome and so easy to navigate!
