Coolant leak problem found? Maybe - PeachParts Mercedes-Benz Forum

#1 09-21-2002, 07:10 PM

I have a 420 SEL w126 chasis with a coolant leaking problem.

I finally think I found where my coolant is leaking from. It seems a hose was cracked. I looked down and I could see the coolant spitting around. I took off the hose, and notice it was cracked.

Can anyone tell me what hose this is? I'm assuming it is a coolant return or supply hose. If i trace it, it seems to go from the engine block to the heater core at the fire wall. There are what seems to be 3 hoses here. Any idea which one i'm looking to replace? And what part #?

da - it is a heater hose BUT without seeing a pic of it this type of question is a hard one to answer. That is the reason you aren't getting much of a response. Can you post a pic of it. You can get ahold of Phil at Partsshop.com and get him to fax you a picture of the hoses in this area and try to identify it from that.

Ok I found out which hose it is.
It's this one:

I can't replace this myself...any idea how many hours a shop will charge me to replace this hose?
