Hello new to the forum. we aquired a 07 Montana. the issue that has developed is that there is no heat at idle. As soon as you step on gas instant heat. Coolants good just wondering if anyone has dealt with this issue. thank you 3.9l v6
 
what does your temperature gauge read at idle, if too low your thermostat may be stuck in the open position
 
x2 check thermostat. also you said antifreeze level is good ? maybe air trapped in system ? anybody change the water pump or hoses latley ? or add any antifreeze ?
 
gauge is normal. comes up to operating temp normally and doesnt flux. no work has been done to this van besides oil changes and a couple bearings.
