I have a 1991 Civic DX with a D15B2 engine. I took it to a shop to have the passenger side axle assembly replaced (previous owner had driven it with a torn CV boot for some time) and the valves adjusted. After 20 or 25 miles of driving after I got it back, I noticed some smoke/steam coming from under the hood. Upon looking in the engine compartment, the steam was from coolant being sprayed onto various hot parts of the engine. It was everywhere, but seemed to be coming for near the distributor. Looking closer around the distributor, I saw a fitting on the head that looked like it was supposed to have something bolted to it, and I assumed this is where the coolant was coming from. This fitting was on the side of the head facing the rear of the car, near the right rear corner of the head (by rear, I again mean rear of the car - I get a bit confused by transversely mounted engines). But in looking in the one manual I have (Haynes) and online exploded diagrams, I can't seem to find what might bolt on to this fitting and I can't seem to find any loose hoses that might attach to whatever might bolt to this fitting, so now I'm not so sure that the coolant was coming from there. I'm attempting to attach some pictures. If it works, the first one is an orientation shot - the fitting in question is hidden from view, but roughly where the red arrow is pointing. The other three are shots of the fitting from various angles.
Does anyone know if something is supposed to be bolted to this fitting? And if so, is it part of the cooling system; could my coolant be coming from there? Is it something the shop could have messed with or accidentally damaged while adjusting the valves?
Thanks, Keith
