Hi and thank you for any help at all that you can give mr. I have a 2008 chrysler town and country touring with a 3.8
my issue just started or at least I just noticed it. My engine runs cold but my heater blows really good hot air. After driving it on the interstate for 20 miles and pulling over to pop the hood I can literally run my finger all along the exhaust manifold all the way up to the block and not get burnt at all. My engine just does not produce heat the way it used to. Nobody in this area seems to know what the issue is. When I call people to ask questions they don't believe me. Because my heater blows hot air to the point where it hurts if you hold your hand there to long they say it is impossible for my engine to be running cold. So that is my issue. Any assistance would be greatly appreciated. There was someone at advance I showed it too and he had everyone look at it and Noone could think up any reason at all.

I don't know what you think you need assistance with but you don't have a problem.

You should connect a scan tool up and look at the ECT data PID to see what the engine coolant temperature actually is. If the engine was running too cold, the PCM should be flagging a P0128 code.

I googled this issue but could not find a situation like mine. Everybody who had a cold running engine didn't have heat. It took 45 minutes for my engines Guage to get to the halfway mark and even after running it for 45 minutes then driving on the interstate for 20 miles I could still run my finger along the engine block and exhaust manifold and not get burned.
I want to thank you for helping me and responding so fast but could you tell me why it is the way it is? 2 weeks ago my engine got hot enough I could have cooked on it.

Not sure you have a problem at all. It's freaking cold out and some engines (at least some older ones) would run exhaust out thru just one exhaust manifold for a time to heat up intake faster so it would run well when that cold.


Mods can find where your message came from by general location and when that much below zero anything can cool down that fast.


Does temp gauge read cold but heater works fine? That doesn't add up if so,

No the temp Guage is reading between the quarter and halfway mark. About midway in between the two. And lol it is freakin cold and maybe it has something or everything to do with that. But I checked under the hood of a friends car and his was way hotter. Like normal hot. So that is where my concern came in at. But that bieng said I have never messed with my engine in winter before so maybe I'm concerned about nothing. Just would like to be better safe than sorry.

Just maybe your fan is running when his wasn't blowing that ice cold air onto the exhaust manifold.

If the heater is hot, then the inside of the engine is just fine.

Drive on down here to Florida. I'm pretty sure you won't be able to touch the exhaust manifold without leaving some skin on it...Cool

Sounds normal so far. It's cold - I'm in that shat too not quite as bad but used to the scoop. Engine fans can and do run especially when vehicle's heater setting is for either both defrost and floor settings or just defrost which would cool the crap out of the exterior of the engine not inside it with the coolant which reads fine and expect that too no matter how cold.


Just driving along adds wild extra wind chilling force too so no surprise yet IMO. I try hard not to have to open a hood outside in that cold at all thank you.


If just curious about this go get an infrared touchless thermo. Radio Shack or other place has them the size of a key fob.


Ahhhhh - I'd rather if you must test temps like exhaust manifold you NOT use your hands no matter what the weather you can't be sure exactly so don't do that again by hand test,

I couldn't get anything accomplished on monday. But when I did get to see the mechanic the engine was producing heat. So I assume everyone here was right. He did not have a way to check for that code and when I did open the hood for him and it was warm we decided not to try and go further with it.
thank you very much for replying so fast to my post. I hope I don't ever have to work on my van in the cold again. Thank you

You're welcome.

Closing this now as solved.
