Wont warm up even with new thermostat
Hey guys,
I have a 2001 Alero 2.4l and live in Saskatchewan where it gets cold, up to -40C in winter. My alero however doesnt like to warm up. Last winter I changed the thermo with a stock one, 180 deg. and still the same problem...the temp gauge barely gets past 1/4 and heat coming out of vents is a huge issue for defrosting! I put a carpet infront of the rad, but that still didnt completely solve it, yet helped somewhat.. Im in search of major help as I have no idea what else that could be causing this problem? My gf has 3.1L alero and hers warms up great, but dont no anyone with a 2.4. Would could possibly be the problem because its killing me with the lack of heat with the car not warming up. Ps-It dont even warm up regardless how long I drive it.
Thanks

hey man, my alero has the same problem, it can run for an hour outside and still not warm up. what i did last winter was cardboard in front of the rad. i also dont have my heat shield on my header, so that will probably help this winter.
but my first winter, going down the highway, it wouldn't even get to operating temperature. my thoughts is that it's a aluminum block, and it doesn't put out much heat with only 4cyl.
but i do have to say, this car will start no matter what temperature.
-50c with the windchill, alero turned over and started without being plugged in. ya. it wasn't happy, and i didn't have heat until i drove it.
note too, if i leave my car in a higher rpm, it warms up faster for city driving, dont go crazy, but instead of 5th gear in town, i'll cruise at 4th, or even 3rd.

Hmm, thats wierd bud. I thought it might be something else with the cooling system but if its doing it on yours then im not alone. How about putting a 195 degree thermo in the 2.4l? I would definitely try it however im not sure which 195 thermo i could put in there that would work because they make none for 2.4l, just the 180. Anyone else have this problem or tried the 195 thermo?

i didn't think changing the thermostat would help. i thought it stayed closed until the temperature reaches 180. so if the coolant isn't there it's not going to change much. i could be wrong on that though
look at the other thread i created, it's about a circulating block heater. help defrost the window in the mornings atleast

Correct, the factory thermostat is 180 already, which is just a little bit under the 1/2 mark. If it's not even getting there... your car is running cool even without any coolant circulating through the radiator, which is strange... lol

Try living in an area conducive to human life.... -50C is...wrong. Thats an emergency condition, and the gov't should fly you somewhere warmer... like... 0C

Wild chill does NOT effect a car. "Wild Chill" is the cooling effect on bare human skin.
Could this be a heater core issue?

How do you figure? If there is no wind, the engine will stay as warm as the air around it, however, if the wind is constantly blowing cold air around it, the engine won't have that heat.
Yes, when its just sitting, off... it does nothing, but to think that moving air doesn't affect and engine is goofy.

Wind chill is the cooling affect of cold air on someone that is warmer than the air itself. If the air hitting the engine is cold enough, then yes, it is quite possible that the engine will never get warm enough to blow warm air. Considering -50C is -58F... thats pretty damn cold. Not to mention the car will be moving probably quicker than the wind blows, so the cooling affect is only increased.

Yes you are correct that temp of the air and "Wild Chill" would affect a car, when it's moving. Thus the reason why a car can stay cool on a hot summer day with temps over 100 and the humdity at 100% and the A/C on full blast on the intersate while moving at 75 MPH
However if you re-read this thread and his problem, he's not saying too much abou the car warming up when he's driving it. So my statement about wild chill not affecting a car is correct. You're statement is correct as well, when the car is moving

i'm saying with the car just sitting... it still comes into effect, unless he has it in a garage or something.
if your parked outside and its idling, the wind is still going to rip heat away from the engine ungodly quick at those temperatures.

Yes, Canada is cold haha. If i could give you guys some better descriptions, my heater doesnt work that bad, its hard to say because of my temp. gauge. I just put a carpet infront of the rad today and that solved some of my issue but its not that cold today however. You guys think there is a block in the coolant line? I would thing that would lead to overheating no? Im open for suggestions?

i put card board in my rad last winter, helped with the wind and while going on the highway, doesn't help sitting unless the rad is getting hit by the wind.
i assumed if there was something wrong with my coolant, my car would overheat or something during summer. but it never does. and the first winter, my motor was brand new with brand new coolant.

Now I have to ask after you drive it and it gets as warm as it can are the rad hoses hot, warm, or cold.
If the hoses are cold them the thermostat is still closed and doing its job. If the hoses are warm or hot then the thermostat is opening to soon and yes this can happen with a new thermostat ( i had to go through 4 stats one time in my truck)
