I start my car early in the moring so it will warm up. But latly my heat won't come on. It will only start working when i start driving. and it still isn't very strong. Anyone know what the problom good be. and if it will be easy to fix????

 

Does your car (coolant) warm up normally?

 

ya the engine warms up good

 

There is a coolant line that runs from the head to a "valve" near the firewall. It then runs to the heat exchanger in the heater unit, and back out right near the thermostat. Verify that the coolant line is not crimped or blocked off and that the linkage from the heater unit is still connected to said valve...

 

What Dustin said plus...

Remove your exhaust manifold heat shield if you have one and this will allow heat from the exhaust to soak into your radiator, increasing your coolant temperature. Your engine won't run any hotter, but your feet will catch fire! The guys with headers know what I'm talking about...

 

My heat sucks too Gonna HAVE to do something about it.

 

I bypassed the heat system in my CRX and removed everything under the dash. I have no A/C, heat, fans, defroster... heheh

 

ok the fact that it works when you're moving but not when its parked leads me to believe that one of your fan motors isnt workin. Check out the manual (on my sig) and research the heating system. In addition to that there are 2 valves to open, the *** adjustment from hot to cold usually opens them but if one of the 2 cables that pulls them open came off it wont open one, these 2 valves open up hot coolant flow through the heater core. One is under the dash on the passenger side and the other is against the firewall on the passenger side of the engine bay, its one of 2 coolant lines that runs inside the car (in/out) the in line has the valve, its on top. You'll see it. make sure they're both opening all the way.

 

: / wrong way to do tings... i bet your thermostat is stuck open or something to that effect. u need to figure out 1 of 2 tings. why isint the coolant getting hotter. or why isint the coolant getting to the heater cor efficently
