I’m in search of a replacement corrugated cowl drain hose for my GTV6. None of the usual suspects have this item as far as I have been able to find. Anyone have a spare or thoughts on where I could find one?

I used a piece of appliance drain hose, probably from Lowes or Home Depot.

Thanks for the tip. Do you happen to know the dimensions? Mine is so deteriorated (and up on a rack where I can’t reach it for a while) that I can’t get a decent measurement.

I sold the car and I am unable to measure anything on it.

Actually I think there is no drain hose on the GTV6 radiator. Either you pull off the bottom hose and let the coolant run out, or screw loose the bottom drain plug which has the same effect. That is water running all over the place.

At later stage there was an aluminium aftermarket radiator which had a tube at the bottom of the radiator to let down the fluid. But that short tube was so wrongly placed and tight to body that it was imposible to use it for a hose.

So are you looking for something(drain hose) of imagination?

Nope. As stated by @ghnl, the cowl drain is unrelated to the mechanics of the car. It has everything to do with keeping water out of the cavity above the firewall between the engine bay and windshield.

Maybe better luck this time :) Hose G to point G on the fire wall. Should be the right part as cavity draining hose under the windshield. If its right, its how it looks and also a part number to show for!

Looks promising! Thanks for posting the diagram.

I found what I think is the remaining hose that was left over from the gtv6 installation. It is 3/4". You can have it for the cost of shipping but you may be able to buy one for less.

EB101 is the new owner of my car. He may be prepared to measure the hose if you PM him.

The gtv6 is at my buddy's shop currently, we'll be working on the car tomorrow evening, I'll see if I can get a measurement.

The hose I have on my car has a white plastic fitting that mounts to the firewall, like the above pic. But mine has a 90 degree elbow on it. The tube itself seems to be a rubber accordion that slides over the plastic portion.

Ed, The hose you installed has a 1" OD (measured with calipers) and I am fairly confident the ID is .75". The hose isn't .25" thick, it is because of the ribbed texture for the large difference in diameters. Attached is a pic showing the hose, it appears to be holding up well so far.

That is it. I still have the remaining piece of appliance hose from which it was cut. It is most likely generic dishwasher hose.

I know this thread is 3 months old, but I finally found a hose that will fit my 85 gtv6 at Lowes. Incidentally, the ID for the hose I found was 1.06" (measured with calipers). The ID of the original hose I have is 1.08". My question is: did the original hose need a hose clamp of any kind? Mine didn't have one, but it seems like it should.

The drain hose from the factory had a recessed ring inside to match the elevated ring on the white plastic port that sits on the firewall. It takes a bit of wrestling to separate them... so I doubt a clamp was needed. But your hose won't have that feature, so you can decide if it's needed now.

Can you add a pic to show the hose you found at Lowe's? May save others some time when they go looking.

From the example I have here, there was a long hole on one side of the tube. Probably this tube sits too close the the heat of the engine block. Any new tube may encounter the same fate over time. It's a tight squeeze between the engine and firewall. Probably not enough room for a home-made heat shield, and would be difficult to mount unless the engine was out... is my guess.

So that's my other question: what is the best path for the hose. I actually purchased a heat shield sleeve to protect the hose, but I'm trying to figure out the best path for it. Would you- or anyone else- have pics of the hose mounted in the engine bay WITH the engine in?
