What are possible causes why coolant drips from the bottom of the oil pan when the engine is running?
ATrek
There is a plastic cooling system housing on the passenger side top of the engine. There are three hoses (radiator hose, heater hose and overflow reservoir hose. All different sizes.) connected to this housing and an electrical connection. This part is molded in two separate pieces then heat welded together. Because of the way it is designed it is practically guaranteed to fail. It is common for this part to develop a slight seepage between the two molded parts which will run down the back side of the engine almost unnoticed and drip from the oil pan. If this is the case you will find scaling and lime deposits around the bottom portion of the part toward the intake manifold.
