Coolant to engine locations

[divemaster5734]

Are there any coolant to engine connections on the driver side?
‘90 7.3idi engine.
The heater hose between #1 and #3 cylinder is obvious.
Just wondering what’s on the even side that might be hidden from sight between the oil cooler and exhaust manifold.
Still trying to hunt down a water leak.
There’s another issue but I’ll post later after I verify conditions.
Thanks

Your water leak could be from one of the freeze plugs, on each side. They can get corroded and leak.

I think I know what you mean here. There's the block drain down low around the oil filter. I also believe that there's one on the rear oil cooler end cap. The heads are interchangeable so there's a square headed 1/2"NPT (?) plug toward the back of the head. Imagine the heater hose connection, flip the head around 180*, and that's where you'll find that plug. I may be wrong on the thread size of the plug. It's whatever size the heater hose connection and the engine temp light senders are.
