I have a leaking radiator hose on my 1993 190e. It seems like too simple a repair to take to a mechanic, and feel as if I could do this myself. Does anyone here know of a good manual to demonstrate the proper way to tighten a leaking hose. It looks as if it wasnt attached properly. Any help would be great!
Thanks,
Jeff
You should probably replace it, and no manual will help much. It's easier to cut the old hose and to use WD 40 when applying the new. Use the other clamps as a guide to how tight they should be.
It is most likely your radiator neck is cracking therefore leaking. Change the radiator and hoses while you are at it... It is fairly simple job.
Two clips to release the fan shroud Two clips to release the radiator. Cut old big hoses off with razor knife Loosen tranny fluid line if applicable.
Reverse As for tightening... once clamp is taut, turn one or two full turn... you want tension... not cranking all mighty force on plastic neck. Just some good tension.
Never put WD-40 or any oil lubricant on rubber hoses... will cause them to swell and fail prematuely.
If the leaking occurs on the radiator end of the hose, most likely is the cracked radiator neck as mentioned by Tiger. The neck is made by plastic. The cracked neck is very common for MB made around 80s or even early 90s (at least those are the MB I am familiar with :-). The replacement radiator should have metal reinforcement inside the neck. Make sure that is what you get.
Most radiator specialists should be able to replace the plastic tank (for about $200 for me two years ago). It is an easy job for them. If you can get decent radiator at good price, go for it.
