Car all of a sudden wont blow hot. I came home (in another car), looked under the car, and noticed a pool of coolant. Not sure if they are related or not as it appeared as though one of the hoses may have been loose. Anyways, I re-seat the hose, and begin to refill/burp radiator. I turn on the heat while im doing this and it doesnt get hot.

I had heat 2 days ago. I manually move the heater control valve on the firewall and no luck. It blows cold but no heat. Any ideas?

 

it sounds like you may have a clogged heater core or a bubble in it. when you 'burped' it did you have heat set to max. that whould be about the only thing that whould stop you from getting heat.

 

I put it to 3, not 4. How would i know if it were a valve or soemthing simple?

 

if leaking coolant inside the car on passenger side is ur heater is clogged may be is done. My is like dat to is my heater is hot but not dat hot an is leaking cooling on passenger is pain in the *** remove the head dash to replace heater core good luck hopefully is not ur heater core

 

tyr to jack just the front of the car up and get coolant funnel kit from a parts store or something set it up to the radiator filler and burp it that way usually you the need the coolant to be higher than the motor if its a stubborn burp

 

when was the last time the thermostat was replaced... try replacing that and fresh antifreeze

thermostats do go bad. replace it. i bet therein lies your issue.
