i have a 95 c36. the car just started leaking coolant its hard to see where its coming from but its on the outside firewall below where the oil filter is located. can this be the heater core? there is no coolant inside the car.

Possibly the heater connection on the pipe from the cylinder head,#10 in this diagram;http://www.detali.ru/cat/oem_mb2.asp?TP=1&F=202028&M=104%2E941&GA=722%2E328722%2E424722%2E604722%2E605722%2E629&GM=717%2E441&CT=F&cat=44V&SID=83&SGR=180&SGN=05 .
Good luck ,the access will be quite tight.

thanks for the reply but it doesnt seem to be coming for the rubber hose. its dripping from the firewall below the rubber line you mentioned. any other ideas? i'm just praying i do not have to remove the dash.lol!

By the look of it there is a metal pipe through the firewall with the heater hose connection on either side, could it be the inner connection that is leaking and running back down the pipe?

its really hard to tell since everything behind the engine is soo sight. i tried looking from under, but the starter is in the way.
