i have an 06 cobalt ss/sc. its completely stock, in the winter it doesnt get up to operating temp. i let it warm up for 5-10 mins and it barely gets to 100 degrees. even after i start driving it barely gets over 120 and it seems to lag alot anyone have this problem?

 

Higher temp thermostat
/thread

 

lol you don't need a higher temp t stat, yours is stuck open you need an oem replacemtent

mines doing the same thing but mine gets up to around 140-160 my check engine light is also on for a p0428 thermostate code no big deal to me i still have heat and when it gets above 50 deg outside it goes off

 

Mine takes a good short drive to get up to temp. Maybe about 10 minutes actual driving time

 

you could do what he says, or you could re-route the top coolant tube directly into the supercharger inlet, this method will definitely get your car up to operating temp

 

is this the part he needs?

thermostat

 

lol wow, so you dont let your car get up to operating temp huh? hope youre not doing any spirited driving. whats the winter rating on your oil? ex: 10w30, 5w30

lawls

 

Mine is having the same Problem.

 

You don't know that...my answer has just as much validity as yours.

 

lol, ecotoecs are designed to run most efficiently in the 180-188* range, they come with a 180* thermostat for a reason. What degree t-stat would you suggest? just curious

 

what is the weather like where you are in the cold weather here my car will only get to about 160*

 

When it's cold out, mine still gets to 185* within a few minutes of driving.

Just curious, how many miles do you have OP?

 

i only have about 27k on my car but it has always done this since i've owned the car

 

That's odd. I don't know what would cause that. I'm on 92k, stock thermostat. No problems here.

 

If he's always had this issue and it's only in the winter time I doubt its getting stuck open. He can try what you suggested and replace with oem...if that doesn't work then he can try what I suggested and get one with a higher temp rating.
And fyi mine has always run around 195-205 since the day I bought it new.

 

ive got an 05. mine did the same thing after owning it for 2 yrs. its just a bad thermostat, thats stuck wide open. it wont realy hurt your engine is what the dealer said to me, and it was covered under warranty.

 

let us know whats wrong when you find out

 

If youve got an 05-06 and under 60k(100k miles for newer) miles just go to the dealer and get a new thermostat, thats for the group of you with the issue

 

my car only has 52000 so its out of warranty and its about 40 degrees out now and barely gets to 120 degrees. i bought a new thermostat but changing it out is a pain.
