Gurgling Noise

[turnipsock]

When I was playing around with the coolant overflow pipe, next to the radiator cap, I thought I would blow through it just to make sure it was clear. There was a gurgling sound as if the other end was sitting in a pool of water.

I didn't try sucking, even though the antifreeze is quite tasty.

Does anybody know where the overflow pipe goes?

One end fits next to the radiator cap. Then it clips onto the fan shroud, goes to one side then downwards, and exits just below and behind the front valence.

It will gurgle, because the top of the pipe sits level with the coolant.

But I think turnip blew through the top of the pipe Paul. Strange one! (There has to be a punchline to this thread!)

Turnipsock, we are talking about the very simple little plastic tube, which connects to the radiator near the cap, and simply goes sideways and down and exits just below the valence? Or is it another, perhaps more complicated and interconnecting pipe?

It's the one that is besdie the radiator cap, all it does is take any fluid away when the radiator cap leaks.

However my overflow pipe seems to head down the back of the wheelarch on my car. The reason I took it of in the first place was that it didn't look like that it was routed correctly.

I guess I'm going to have to take the wheel arch thing out to see what is going on?

For an accurate answer on where the pipe should go, its going to be neccessary to detail the exact car and year. The W124s had 2 major updates in their life. I have a 'series 2' and it has a different layout, I think, than yours.

It's a 1993 320CE

Turnips is a series 2 also (as far as I can remember)

Series 1 (- 89) Black Protection strip along car, no bottom plastic.

Series 2 (89 - 93) Bottom plastic panels, semi colour coded bumpers. 230 replaced wit 220. 4 cyls get 16v (I think)

Series 3 (late 93 - ) Different bonnet/grill/star setup. Electric driver mirror. Different rear with chrome (saloons). Fully c c bumpers. Standard airbags

I think that drain pipe takes water/steam away in the event of cooling system overheating, when the excess pressure 'opens' cap spring.

I take it you don't have an expansion tank then turnips? My overflow pipe (on the 1993 200E) comes from this tank via the pressure cap on it (no pressure cap on actual radiator) and exits to atmosphere.

I dont wish to seem rude, but who plays around with a coolant overflow pipe? If you hadn't you wouldn't now be worrying about where it goes!

Gently lower the bonnet and go and have a nice cup of tea.

I know it's wrong to play around with the overflow pipe, but it tastes so good.
