Heater smells when on
Unsure as to why no evidence and should have had some. New one could be
defective or broken while installed. It's really the only item to make
the odor in interior.
Are you consuming antifreeze? Pressure test system for leaks, If you paid for this job it's theirs to take care of!
liquid will very slowly evaporate and the heater box if with A/C should
have a drain so no volume of antifreeze should be held there but some
Odor should go away in time. If heating run it hot and
open windows if needed should speed it up. Products like Lysol down
where incoming air comes in from near where wipers attach could help.
Hey - know that engine antifreeze is a poison so if any sign of an ill effect get this fixed, u
cant allways find a coolant leak by looking at it. it only takes a tiny
pinhole leak to squirt it out when the system is warm and under
pressure. the core would need to be pressure tested to know for sure if
its leaking. one weak spot on lots of heater cores is where the tubes
come in thru the firewall and attach to the core body. sometimes that
joint can get a tiny stress crack and start leaking.
as for why
the smell is worse now, it could be that when he took the old core out,
coolant from inside it spilled out of the core into the core case. or
its even possible that the new core is defective, again most likely
where the tubes join the core body. either way, a puddle of coolant in
the case can cause the film on the windshield in defrost mode.
