Small Coolant leak

[scguy]

I have a small coolant leake from one of my hoses (99 c2). I have found which hose and have looked at the hose diagram (kinda confusing diagram and hard for me to even tell which side is the back of the car).

I also spoke with Jeff Clark who sent me the diagram but unless I can give him a hose or part #, its hard for him to figure out which hose I need.

The best way for me to describ it is this:

The leake is below the engin.

When I crawl under the car, the are two black rubber hoses exposed (one behind the passagner seat and one behind the driver seat). They are actully more like under the left and right rear seats. These aren't way up in the engin bay, they are right at the bottom of the car.

The one behid the passanger seat is the one leaking and it looks like the clamp has dug into the rubber a little and its dripping every 5 or 6 seconds.

I looked to make sure the leake wasn't coming from a higher location and Im fairly sure its just the hose.

I figured I would probably replace both these hoses since the other one kinda looks old too but I can't figure out the part numbers.

If someone has a good picture of the undearneath of their car, please send it to me and I can show Jeff which hose Im talking about.

Thanks in advance for your help.

Do these hoses come off of a hard pipe and connect to the engine and that hard pipe goes to the front of the car?

Ok I looked a little closer today.

The hose itself is about 6 or 8 inches (shaped kinda like an S).

Its in the back right side of the car, about a foot from the back bumper.

It does come off a hard pipe.

When I stick my head under the back right side of the car, its the only black rubber hose I see. Everything else is metal.

I usually go with the factory oem stuffs for my cars, esp the Porsche, those German engineers and the part replacements that come from from the factory. " You are only as good a your gear", or parts as the case may be.

But these Coolant over flow tanks are just plain big and ugly.

Does a maintenance aware H2O cooled 911 owner need the capacity of this ugly tank?

If I am correct coolant overflow tanks started out as an add on back in the day. I got my first one when I was just trying to keep my junker Austin Healy from overheating

But back on task. I relish looking under that little lid in the rear of this car almost as much as the driver's seat...almost. Just to check for????

Anyone have a more attractive coolant overflow replacement??? Prolly cost more/less but if you need one the p-god wants about $250. (But check first I could well be incorrect on that price).

I only quote that$$$ as a baseline. The only trick is a relief valve on top of the stock overflow tank.

The NSX guys over on the NSX prime love to replace stuffs like the coolant overflow tank. Someone over there produces a stainless tank with an old timey sight tube that is waaaaay cool. Would gladly cough up the $$$$ for something like that. Betcha I'm not the only one either.

I have looked on the bay to avail. If anyone has an old Coolant Overflow Tank that is not repairable (good luck) I would gladly pay shipping to 80918.

And I will share the results too.

Don't intend to kidnapp this thread.

Hope this reply is not in the wrong part of the forum, or something else untoward. Just started writing and the topic took on it's own life.
