Hi everyone! I have a 2005 Crossfire Roadster that was mysteriously using up coolant. Couldn't find where it was going, wasn't leaving any puddles but every 3-4 days my "Low Coolant" light would come on and sure enough my coolant would be way down. I was terrified that it was going to be a failing water pump or head gasket or something else that's terrible.

Today I was adding coolant for the umpteenth time and I finally spotted it, a weird "S" shaped hose coming off of a "Y" connection to what I believe to be my upper radiator hose, traveling to a "T" connection to another hose traveling who knows where.

I have attached a photo and tried to highlight what I could (Sorry in advance for underhood filthiness, and horrible "Paint 3D" drawing lol). The red "dashes" highlight the hose in question, the blue "arrow" points to the source of the leak which is an abrasion on the front side of this hose that cannot be seen in this photo, the blue "circle" highlights the puddle of coolant forming from the leak.

Also explains why I couldn't spot it...Coolant leaks onto top of fan then drips down behind fan, fan instantly blows it completely away leaving no puddle under car and only the very occasional half second whiff of "Hmm was that antifreeze"? (Clever Girl)

Anyhow my questions to everyone here are 1. What is this hose called? 2. Where can I buy one 3. I am unsure about what kind of connectors that hose is using, does anyone know? When I try to look up "2005 Chrysler Crossfire Radiator Hose" I only get "hits" for the large upper radiator hose, not this crazy thing in the picture.

Thanks for reading all this! Any help/advice would be greatly appreciated!

You might want to replace the whole thing and flush the coolant. You can go to a Mercedes-Benz dealer and ask for that part. I don't think they sell the individual piece though.
Yours shouldn't be rubbing like that. It looks like it's routed wrong. Maybe somebody replaced that hose with the wrong size?
See the picture of mine below.
Here's a link to one I found on e bay.

Radiator hose

 

Thanks so much for your answer! I couldn't find what I needed anywhere (forgot that my car is actually a Mercedes). That hose is not misrouted or the wrong size, my Crossfire is a salvage repair, previous owner killed a deer with it and his insurance totaled it out. I bought it from him for a great price. Car was ugly but ran good, I have replaced broken headlights and damaged grill, car now runs good and looks pretty good but underhood stuff is still a little "U" shaped. Price for hose is not nearly as bad as I thought it would be, When I replace it can I just lower coolant level, replace hose and refill? Or is that coolant flush you mentioned a necessary procedure? Thanks again for your help!

P.S. Your underhood is spotless, I am truly embarassed, I'll have to find something to clean that won't wreck the electronics.

I highly recommend buying from Rob here at Needswings !!!

 

Don't buy from Rob at Needswings, go buy cheap generic parts that partly fit and end up causing more trouble down the road. WHy buy the right part when buying cheap generic parts results in longer, more interesting threads and more drama.

 

This is only sarcasm...LOL

Like everyone else suggested, Needswings.com has that part for a lower price. They also have the correct hose clamps. You don't want to use those auto store screw clamps.
I should have thought of them first.I've never had any trouble with any parts that I have bought from them.

Thanks for the comment about the engine bay.
You can clean your engine bay with no real worries. I clean mine with a spray bottle with soapy water and wipe it down with a damp microfiber towel.

 

I would contact fcpeuro.com via phone. They do not have any listings for Crossfire parts but they have beaucoup MB parts. I would search 3.2L radiator or coolant hoses for a 2005 slk320 or c320. If you send them a photo I'm certain they will have the parts you need. I have been doing business with them for a number of years and find they provide excellent service and good pricing. They offer both certified MB and other competive brand parts.
Cheers
