what would be some reasons why my heater no longer works in my crx 91 hf?(car blower works inside just no heat)
also FYI the bottom hose returnign to radiator is not heating up the way i would like to see... already changed thermostat..

 

your heater core is probably clogged flush it out.

 

also other than the heater what would cause a cold bottom hose?
b18a engine (if need to know)


methods on how to do this?

 

How long are you waiting for it to warm up? What temperature is your thermostat? You could also check the valve that opens up into the heater core to make sure it's not stuck closed. Does the engine warm up normally?

 

i usually don't just get in and drive i let it warm some... and the temp gauge reads dead center, after warmed up ... so i don't know...
