Heat problem in 85 yota 4runner

[Milk Man]

I just got my 85 SR5 4runner and I changed plugs,wires,oil and filter. It did not have much heat coming from the vents so I drained the antifreze and ran flush for 15 min's. Still not much heat from the vents. Do I need to run the flush longer or what do I do next. Thanks for any help

chnage the thermostat, 190°-195° will do. good chance yours is stuck open, not allowing the engine to properly warm up.

if you aren't getting much or any air blowing out the vent's , try replacing the blower resistor, bottom of case next to blower motor.
