Cabin sometimes smells sweet after long drives. Level drops every few weeks. Heater core? Water pump weep? Head gasket paranoia? What did you check first?

Sweet cabin smell = often heater core. Check passenger footwell dampness/foggy windows. Pressure-test the system; UV dye helps. White exhaust smoke + mayo on oil cap = different (head) problem — don’t ignore that combo.

Pressure test found a tiny hose seep at the firewall. $40 hose, not a head gasket. Test first.
