All,

A couple of weeks ago, I replaced the water pump in the Hyena ('88 Westy WBX).  The past few days, I've thought I smelled a faint trace of coolant in the van itself.  I checked the hoses, the radiator, the front and rear heaters (best I could using a camera probe and mirrors without removing all the plastic) and have found no leaks.    I checked the bleeder on the radiator, no leak.   I have seen no noticeable drop in coolant level in the reservoir.

Any ideas on where I should explore next?

I have also noted that my temperature gauge is now running a little lower (from top half to bottom half of LED ... about a needles width).   I plan to open both heater cores wide (they are partially shutdown at the moment), park with the nose in the air, run it for a few moments, then open then bleed the system again just to ensure I do not have an air bubble.
