2007 toyota 4 runner heater core

Asked by Jan 06, 2018 at 02:13 PM about the 2007 Toyota 4Runner

Question type: Maintenance & Repair

Bought a 2007 4 runner about 3 months ago.
Inside if windshield keeps getting really dirty/hazy
within about 3 days of cleaning. Cabin filter is
clean. Heat and defrost are working but pretty sure
we smell antifreeze. Any other ideas before I take
my whole dashboard off or paysome way to much
to do it?

Are you losing coolant too? If so it's going to be the heater core. HTH. -Jim


yes make sure your not loosing coolant. but you said you just bought it right? iv'e known of a few cleaners that detailers use when the sun hits it through the windshield the vapors from the chemicals will rise onto the windshield causing a haze. just putting that experience out there.

Ya not seeing coolant leak anywhere else so I wasnt sure. Someone was telling me there was no way it was the heater core is it wasn't leaking on the floorboards. I definitely thought it was something they cleaned with at first, but have cleaned the window 10+ times since I bought it and it just keeps coming back. Using safelight window cleaner since my roommates work there.

So how big of a pain in the butt is it to do yourself? Both roommates have some mechanical experience and I really don't wanna pay like $800


wait to make sure you are leaking. that's a lot of work if your not sure.
