Hi All, on cold days (even in the 20's), my 2015 accord simply will not warm up and start blowing warm air to the front defroster until the car is driven for a while. The temp gauge just won't move if the car is left to idle. I brought it to be checked and they assured me it was all working fine. My 2010 accord would warm up in all winter conditions and blow warm air just sitting in the driveway idling, but not the 2015. I think the thermostat is stuck open. Any thoughts? Is it just normal for this car not to heat up while idling?
How long are you letting it idle?
1,2,10,20 minutes?
The Earthdreams versions of engines (4 and 6) are much cooler running than previous engines. It takes,what seems like forever, to get the engine warmed up when performing idle relearn, coolant burping, etc IF I let the V6 simply idle. I mean to say at LEAST ten minutes. That is why they say to run engine at 3000 rpm to get it to temperature fast in that situation.
Have performed this MANY times and it is not a bad thermostat as I can OBD the temperature and it gets up to 195+ only after 10-12 minutes. Rev it to 3K and zip,zip it's at temperature within 3-5 minutes. Ambient temps about 35-40F.
As stated start the car, idle for 30seconds to a minute until the tach drops once from high idle, then drive like a sane person. Usually within under 5 minutes the hot air is blowing, temp up to operating range even at 20F and below.
the 2013 did this from new but that's the way these engines go.
As far as the frigid Minnesota temps I still only let it idle for a couple minutes until off high idle then drive slowly to get everything toasty warm.
You also might want to check to be sure you have no air pockets and coolant is up to level.
