Heater core flush
Heater core flush
Hi folks. anyone have this done?
I get very poor heat from my heater and the weather is getting colder each day
cooltant is in correct level, no leaks, air mix servos work fine, everything works.
which method is the best? compressed air or garden hose? are there any chemicals (myb household) to use?
Thanks
Is it poor heat output or poor air flow??
DO NOT use compressed air, use garden hose.
Is the coolant in the radiator clean because if it is I doubt if your heater matrix is blocked.
Poss probs.
Blocked pollen filter (poor air flow)
Hot/cold air mix flaps, not adjusted/working correctly.
Engine not running at correct temp (thermostat)
poor heat. air flow is normal.
why compressed air is bad?
coolant is not very clean. I dont know what prevous owner did put in there, but it looks like sh**.
cabine air filter is fine, replaced recently
are they adjustable?
engine temp is ok. if thermostat is bad, you get hot air when standing and cold when driving. mine does opposite. cooler when standing and warm when driving (more flow i guess)
