mercedes benz clk radiators

Hey Pancho. Sorry to hear you banged her up but glad it wasnt too serious and you werent hurt. It all depends on where its leaking. As you note its a plastic shell so it may have cracked right at the fitting and its runningdripping to where you see it (there is a metal tank inside the shell that carries the ATF). The only way to know whether you can fix it is to first locate the source. If its at the

Yep have read about some defective radiators leading to contamination of the transmission fluid. Dont want to put another Valeo in it. Called supplier for parts.com and since part was not in stock he was not able to check on manufacturer so unable to confirm that

already determined the broken plastic arm on the cover hings is no big deal especially since it is off completely and thus wont interfere with the normal operation of the hinge. If you want the original first aid kit and owners manual you can probably find them on eBay for much less than what the dealer charges. Or just buy a generic first aid kit adn download the manual in PDF from here mercedes-benz

I went with a 2005 clk 500 for a few different reasons -7 Speed Transmission I get 25mpg or more on the interstate in 7th gear -Radiator Problems clks made before 0903 have a huge problem with radiators leaking and destroying the transmission -AMG Love AMGs for what they are but using it as a daily driver can get very costly Got mine at 59k miles for 16.7k and loving every minute of it

Welcome Swoupy. The W209 clk has proven itself to be one of MBZs best vehicles and the later years (2006) tend to be excellent buys in terms of reliability and price. There are really no major known flaws on this vehicle. Of course that doesnt mean you might not have some problems but there arent any chronic issues as there are with some other models (like the early ones that had bad radiators and

Modern MBZs are as good as the old ones in terms of overall lifetime reliability but they tend to have most of their problems early on and there are certain problems that although rare can be expensive. Examples include bad radiators that cause transmission fluid contaminations and transmissions that were claimed to be maintenance free but actually need fluid and filter changes. I know of no tire problems

There is a very useful search feature on the forum. You might consider giving it a try. As to how to identify the different radiators try this link httpwww.benzworld.orgforumsw203...-have-bad.html The easiest way to know is to look at how the metal banding that joints the end tanks to the core is shaped. The pictures at the above link tell it all.

Forgot to mention - Valeo radiators ceased to be used in W209 after September 2003.

First let me ask a couple of harsh questions. When you said you removed the freon and resupplied - HOW exactly did you do it Was the system just bled to the air or was it recovered. When it was added to the system was the system vacuum evacuated PAG oil added and the system was charged using a PROPER gauge set (two gauges for high and low) and the WEIGHT of the freon added by pound weight Then pressure checked. You are getting cooling at idle - ok thats fine but when the car is in motion the pressures go up and the compressor has to work to covert gasliquid mix to cool. If there is air in the system it wont compress properly and the air will expand more than the freon and the system pressure will be out of wack. Also check your fans - see if they are running properly. If you didnt do the above youll definately have problems First if there is air in the system it wont compress properly and your system eventually will corrode. No oil or not the right amount - youll fry the compressor. If you added the freon improperly you can definately clog the expansion valve. Ive posted responses to AC questions before and Ill say the same thing again. Take it to a qualified AC specialist. They arent that expensive to get a diagnostic fill pressure test and recharge. If you attempted to fill it with a over the counter bottle with a cheepo gauge especially if its been discharge you are asking for trouble - definately no question. Get some crap in the system it will mess up the compressor and valves. Open to the air - youll need a new drier. A complete flush is probably in order as well. Im pretty mechanically competent - rebuilt motors suspensions and have done electrical - the only thing I wont mess with is the AC system. Reason - you can mess it up without the proper tools (vacuum pump good gauge set and a good charging station) The cost of the mistake is big dollars - like a compressor valve drier or popped evaporator (think pinhole leak rip out dash to replace about 15 hours or really hard work). Do youself a favor - it will save you lots of time and a potential heart attack - take it to a AC specialist - not necessarily the dealer - someone local who only works on ACradiators and is familiar with benzs.

Hi Mark Say are you saying there are still baddefective transmission coolerradiators in the 2006 clks I thought they had upgraded that defective radiator a long time ago (at least in the E-class) Now I am worried Is there anyway to check for potential problems I dont think there is a transmission dip stick on my Tranny. Thanks Mike

Hey all I am concerned about my clk 500 with 7 Speed Auto. I have noticed in the last week that my transmission is having issues shifting in low gears. When it downshifts sometimes it is hard. I understand from reading the manual that the car upshifts and downshifts depending on how far the accelerator pedal is pressed. Sometimes my car from first to second gear has a delay in shifting or may be shifting

This changed the viscosity and was causing the gears to slip and hence the thuds. This could have resulted in damage to the whole gearbox which might need changing. The technician said however that there werent any metal chippings which was encouraging. I think I will try and get

It also mentioned that the Basslink T was designed for SUVs pickups and hatchbacks. Therefore I wonder if it will provide sufficient bass from the trunk of a car.

Quote Originally Posted by liquidusculade you only need the intercooler if you are running a supercharger or turbocharger since compressing the air will raise the air temperature. your clk already draws air from the relatively cool front of the car vice the engine bay so i dont think there is much else you can do to keep the intake air temperatures lower. if you are talking about other temperatures

MB is having lots of transmission issues with the 7G. Also 2003 and early 2004 MBs have been plagued with faulty radiators that leak coolant into the transmissions causing catostrophic transmission failure.

I have the same car and you shouldnt need any special instructions for a test drive. I have 150k miles on original engine trans struts exhaust.... This is the most solid car I ever owned. Still sounds and rides like a new car. I got about 40k out of the rears and more out of the fronts. Its not the car its how you drive. You should check the cars manufacture date. There was an issue with Valeo radiators

There was an issue with a defective Valeo radiator that had bad seals and would allow coolant and transmission fluid to mix. I thought that those radiators had gone out of production in early 2003 but I could be wrong about the timing and maybe your 2004 had one Anyhow if this is the case the dealer is correct and the solution is to replace the radiator and do a fluid change in the transmission hoping

Yeah MBZ just wont do a recall unless its a major safety issue no matter how easy the repair might be or how expensive the problems are when it fails. When Valeo radiators started failing in massive numbers many dealers began replacing them when customers came in for other warranty work. They would often tell the customer (and MBZ) that they found a leak during routine inspections.

Keep this thread alive. Ive become really concerned about the symptoms Im having especially after reading something about defective radiators contaminating the transmissions on these cars...I did my research on this model and this specific car and didnt see any recall or dealer bulletin info. My test drive unfortunately was only at low speeds and around residential neighborhoods (I know I shouldve

The second is the sensor and the third (ReceiverDrier) is what its screwed into. Yes it has to be drained because if you remove the switch all the freon will gush out. In some cars like VWs the switch is screwed into the drier but it has a self sealing valve when you remove the switch. The MB does not. If you never worked on AC systems before you can really mess things up - think make it worse. Get

Umm.... not exactly sure bc we didnt get 208s with manual gear boxes in the states but to my knowledge Im not even sure that the manual transmission has any cooler lines that go to the radiator. Cant remember ever seeing that on the c230s and slk230s with manual boxes here. I do however know that the problems associated with Valeo radiators and AUTO trans was a faulty clamping of the radiator that
