2009 Odyssey Heater
My first venture into the Honda line has been received with mixed
reviews. The vehicle in question is a new 2009 Honda Odyssey Touring. The only option added was the trailering package which was dealer installed. Some nice feature and some just plain disappointing. One of my biggest regrets was not opting for all wheel drive. Traction in Ohio winters is tenuous at best. More importantly, in Ohio winters, I would like a bit more heat! I have had it back to the dealers indicating it just takes too long for the engine to warm up. It never reaches half way on the gauge and is certainly less than satisfying in warming the the interior of the vehicle. The dealer mechanic has measured the air temp coming out of the dash as about 160 F which sounds okay, but has not offered the engine temperature. Having called "the factory", it would seem that that check is not necessary. The performance would indicate to me that the thermostat does not allow the engine temperature to reach the 195 design level. Any ideas out there about how I might pursue an improvement? Tom |

Not just for Hondas but for Toyotas as well. At first I thought it had to do with defective thermostats. And indeed, people who had their thermostats replaced under warranty DID report an improvement. But the perceived improvement may have been imaginary. Given the frequency with which I'm seeing this problem, I wonder if there has been a regulatory change to emissions control laws. NOx are a product of excessive combustion chamber temperatures. Cool the chamber and you reduce NOx. Cool it too much without restricting the cooling system and you may actually affect interior heater performance. I see absolutely nothing in any of the official documentation I have (which is now extensive) relating to the problem, so evidently automakers do not believe there is an issue. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

Assuming a 174F (78C) OEM thermostat and a fully-warm engine, an infrared thermometer aimed at the upper rad hose outlet at the head will display about 205F. Anywhere other than that, the thermometer will read drastically lower. I'm very surprised the tech was able to get 160F at the vents. That's hotter than the hot water tap in your house. I'd expect more like 70 or 75. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

I never warm the car up in the driveway, except to clear the windshield.
I get in it and go, and expect when I hit the signal 1 mile away, I am getting some heat out of the vents, just like the other three cars I drive. It isn't happening on the Odyssey, until nearly the second mile. Tom On 1/23/2010 6:24 AM, Elmo P. Shagnasty wrote: > In >, > > wrote: > >> I've been hearing this for much more than a year.

I'm pretty sure the only minivan offering AWD is Toyota's Sienna. So instead opt for winter tires on your Ody. > More importantly, in Ohio winters, I would like a bit more heat! *I have > had it back to the dealers indicating it just takes too long for the > engine to warm up. *It never reaches half way on the gauge My Sienna temp gauge also never rises above mid way. But it throws LOTS of heat after about 5 to 10 min. of driving depending upon outside temps. and is > certainly less than satisfying in warming the the interior of the > vehicle. *The dealer mechanic has measured the air temp coming out of > the dash as about 160 F which sounds okay, It's a big interior to warm up. You need to run the fans, fore and aft, at full speed until the interior warms. Turn off the defroster setting as soon as the windshield clears and run the heat to the floor and mid-level. Make sure the vents in the back of the van are open and blowing. Do NOT operate HVAC on recirculate or the windows will fog. It'll warm if the heater's blowing 160F air but it takes a some time in very cold temps. |
