Re: my heater blowing cold (arturofs)
Check your antifreeze level. Make sure its full. Other than that, you could have any number of problems. There should be 2 black hoses going into your firewall. Both of them should be warm/hot water that goto your heater. If one of them is off, or leaking, then theres your problem. After that, could be your heater control valve, heater core blockage, or thermostat stuck open. I would check the fluid level and heat control valve first

is it the green antifreeze only for "do not use water" or for both
