OK, I did a trip last summer in my then new-to-me Crossfire, and put on about 10K miles over the summer.
Prior to the trip, in fact as soon as I got the car home, I did a complete change of all the fluids, the belts, filters, etc. The radiator fluid looked good, so I let that go. Did the trans filter and fluid flush per Car D.Ologist.
I am now facing another summer trip, which will also be about 10K miles, between May and August.
I have had oil and filter change intervals in the meantime, and did those. Just did a news trans filter and fluid flush (14 quarts, per the "Car D. Ologist" Youtube video, which is EXTREMELY good, by the way!)
I expect to reach another 5K miles before my trip, which will mean another oil change prior to leaving. No problem there.

My BIG problem is I want to change the radiator hoses and do a coolant flush, and put in new coolant.
In checking with all the local auto parts stores, and then on-line, I am coming up with "Out of Stock" or "No Longer Available" on the UPPER radiator hose. I kind of expected this with Autozone and O'Reilly's, since they only handle common cars, and the Crossfire is definitely a niche automobile. But I am having the same answer at our local NAPA store, and also a place called Merles, which in Tucson is where all the professional garages go to get parts and tools. I was surprised at NAPA, but only mildly, but when Merles didn't have it, I started to get alarmed. Merles typically has EVERYTHING, and it's in stock all the time. The most I ever have to wait there is 3 hours for a delivery. I've even gotten Jaguar XK-8 parts there! That tells you something about their range.

When I check online, the situation is the same. NO ONE has an upper radiator hose for a Crossfire N/A.

I REALLY want to change all my hoses before this trip. The car has 50K miles on it now, and I am putting new brakes on it this week, and new tires on it next week.
So, what can I do now? Does anyone have a source or a spare new hose they will part with? All the rest of the hoses are available, so that one hose is the big stumbling block to changing my coolant before my trip.
Ideas? Suggestions? The hoses on the car now look nice, but it has only had easy use up until I bought it. It had 28K on it when I bought it last year, and that was just 1500 miles per year. It was some lady's pet car that she only drove a few times each summer. But last year I was blasting across Wyoming at 90-100 mph for hours, and I am nervous about the trip this year with such old (19 years old!!) hoses on the car.
Has anyone bought other hoses and cut them to fit and then spliced them with a piece of metal tubing to make a complete hose assembly? That is one thing I am looking at right now, but I don't want to reinvent the wheel if someone already has done it, and can give info about what specific hoses to use for this.

The Mercedes part number is 1705012582

Another option ( 2005 CHRYSLER CROSSFIRE ZH ROADSTER #247 A/T RADIATOR COOLANT UPPER HOSE | eBay ). Good luck!

You can search for SLK320 parts on M-B Parts Websites (I use 3 different sites to look for parts). Use model years 2001-2004. You will have more luck locating parts still available that fit the Crossfire. CLICK (This link yields the part number previously identified by Ronman in earlier post.)

 

Anyone know what part this is and what it's called so I can order it?


it's coming off the radiator hose on the passenger side infront of the ecu.

 

That is called a "Duo Valve" or "HVAC Heater Control Valve".
Here is the Mercedes-Benz part number: 0048302084
Here is a link to one, you can search around and might find one cheaper.
Duo Valve HVAC control valve
They also sell a repair kit on amazon. That would be the cheapest way to go.

 

Holy Shat!!! $580....they was smoking something pricing these...that link u sent won't open...man...I'm screwed..lol

 

Needs Wings carries the part. Current listing price point much less. I would specify if SRT or Limited/ Base

Here's another source (good parts house for our cars) for the Heater Control Valve: CLICK

 

Make sure you use the correct radiator fluid it has to be Mercedes or equivalent I only use Mercedes.

 

Very Good Advice!!

 

Good looking out!!

 

Go to Rock Auto:

The link I sent was for FCPEuro.com I don't know where you got $580.00 from, the new part was only $186.00.
I also mentioned that you can buy a repair kit from Amazon. Search for 2003 Mercedes SLK 320.

 

M60A3Driver.. absolutely NO slight against u....the link didn't work when i kept trying it, I looked the part up Google brought all OEM factory prices....I wasn't trying to offend u... the part was $580 on all factory sites. I like Dealership parts, due to a lot of bad faulty aftermarket experiences. ..I appreciate ur help, please don't take it the wrong way....I'm not one of those people!! Sry it came across that way...

Dealership parts prices are way too expensive for the crossfire. You should reference parts from an SLK-320 in the 2004 model year for any parts with the MB part number on them in your crossfire. The membership knows these MB parts are much cheaper for the same item. Good luck!

Thank you...I'm used to dealing with Mini Cooper, I know, different animal, but it only want oem for some reason, aftermarket throws a thousand codes everytime..
