• I am having a hard time with the new to me 2007 V6 Escape

Any help appreciated

• No thermostat in it when I got it. Heater worked great when it would finally get to temp
• Had thermostat installed having issues temp would spike have no heat, then it would go back down. Heater very inconsistent
• Installed new radiator.
• Performed combustion leak test came up negative
• Had thermostat replaced with Motorcraft part (found this fix on another forum). Temp very consistent (monitored via OBD II Code reader) Shop also performed combustion test, supposedly vacuumed filled the cooling system.
• No Heat or very little heat inside
• Shop back flushed heater core, replaced heater core hoses.
• Still no Heat or very little heat inside.
• I do have a lot of experience but mainly pre 80s old school. It amazed me that I had no heat and the car was not overheating : )
• I am trying to follow the hoses and while checking hose temp via hand the heater core hoses are maybe luke warm. I was thinking they should be at least the same temp as the others but they are not. Does somebody have a cooling system flow chart or diagram of coolant flow?
• Thanks in advance

 

Hi Gary,

When coolant is circulating through out the heating system , both hoses should be hot if engine is at operating temp (140 degrees F )

It does sound like the system is filled with trapped air..
One thing you might try, engine cool, engine running,remove the upper hose to the heater core just enough to allow the trapped air to get out then push it back on.When that is done, as the hoses get warm, they should both be approx the same temp and you should be starting to get heat when you turn the blower motor on.
This should solve the no heat problem. If it doesn't , get back to us, thanks.

 

Thank you very Much! I have been going nuts trying to figure this out.
