I have searched, but cannot figure this out... I have a 94 4runner with the v6. It looks like a coolant leak on a small j-hose on the big round part under the exhaust manifold (Driver's side), in front of where the exhaust down pipe is, in back of the oil filter. What is it?

Thanks for the help....be nice to the newbie

Not 100% sure, but I think you're talking about the oil cooler line. Been awhile since I had the 3.0 in my Runner, and I'm not sure offhand if the 3.4 has that or not, but I'm fairly certain that's what you're talking about.

 

The round thing is oil cooler the hose is a coolant hose that connects to the water pump by the thermostat housing

 

hunter4runner, that's the part! So there is coolant in hose #1?

Yes there is coolant in both hoses.
