    92 Chevy pickup, WT 4.3. There seems to be no leaks anywhere, antifreeze levels are right up there for several months now. When I turn the heater temp up there is a strong smell of antifreeze. Anything I should look for? I can't see any leaks anywhere. Just seems strange to me to have such a strong smell.

    Most likely the heater core has a small leak. Replace the lines&the core. It is kind of a PITA but it isnt too expensive. Make sure that you clean up any anti-freeze laying around the core, or it will stink for a while
