Checked all hoses and valves on upper engine and their okay, but when I turn engine off there is a big leak down below and cannot get below engine to see where it is coming from. Topped off fluids when leaving work the other night and on freeway on way home the fluid meter was redlining and just got it home shortly after. Where do you think leak could be coming from?

Went to an oil stop and fluid is leaking where block and Bell housing meet. No pressure check not able to get anywhere for that without fluid redlining. Possible crack in block or intake manifold?

I was under the impression it was a coolant leak try to let us know what kind of fluid in the future. It still cold be a head gasket or maybe an oil line if any in back and possibly the china wall gasket to intake. See picture arrow at front would be same at rear where arrow points there. It cold also be the crossover pipe or o-ring where it attaches at back of engine leaking a pressure check would show that as its coolant.

It is a coolant leak, have not had pressure tested the oil guys just said it appeared to be leaking from where block and transmission met. When I pulled up to Oilstop and opened hood it sounded like it was boiling or steaming from back and below engine and smoking like I had a valve cover leak. O'Reilly's said $39.99 to rent pressure tester and I have no idea how to do that or what to expect and it appeared like a type of steam was coming out of exhaust. Codes 25, 26, and 71 came up on diagnosis yesterday. Nobody helping me here all too darn busy. Any information would be great.

Pressure test cooling system, pull your radiator cap, tester screws right on in place of cap.
