Default engine warm-up

2008 PT, base, 73K miles
Been really cold here lately, around 10F during the day and down to 0F or below at night. Ironically, about 2 weeks ago, the PT began warming up quicker in the morning. For example, this morning the PT reached normal operating temperature in 2 1/2 miles of driving. Used to be it would have to be driven at least 4 miles to get to normal operating temp.

Once it reaches normal operating temp, everything seems OK. The temp needle hovers about mid-scale on the gage as the thermostat opens and closes.

Coolant level is OK, fan seems to be cycling OK, nothing blocking radiator.

Really is nice that it warms up quicker, but just puzzled at why suddenly it is behaving this way. ???

The list below is the most common problems when the engine cooling system is not working properly.

1. Faulty radiator cap.
2. Improper coolant mix.
3. Faulty thermostat.
4. Blocked radiator.
5, Coolant leak.
6. Low coolant.

I would check the radiator cap first.

my guess is the coolant and engine parts were sooooo damn cold on the thermostat/radiator side that the thermostat is staying firmly closed for longer and you therefore feel the heat coming in sooner.

if you don't like that answer, just accept it as a new years miracle and be happy about it. it is was -12f here this morning. girlfriend said the heat was still cold when she got to work (3 mile drive, no traffic)

Not completely off target, but, today I changed out a failed thermostat. Turned out they used a 'FAILSAFE' type. I understand the theory and it makes sense, however, the engineering is quite flawed. This is easily seen just looking at it sitting in my hand. The guide hole for the float was made as an oval instead of round allowing excess tilt to the float assembly and thus allowing one side to go above the prongs that catch it if the car over heats. The angle is sever enough that the car did not need to overheat to lock in the open position.

Replaced with a $7 'house brand' that even came with a new seal. . . all is right with the PT world again.

They are all good answers, I really can`t add much more. You might go to
PT CRUISERS OF S.E. MICHIGAN and ask the same question. There is one
member that works for Chrysler and knows a lot about these cars.
Along with others, He also lives in Rochester. In fact, I live in Shelby Twp.
We eat at the Rams Horn now and than.

OK, thanks for the answers. Going to keep an eye on things for now but otherwise like the fact that it is warming up quicker. Once it gets to operating temp everything is fine so not overly concerned, just more curious than anything.

CRUZ... will look for you guys at Rams Horn.

I have a new thermostat in mine and 2.5 miles after a couple on minutes warm up is about what I get. You may be warmining it up longer at startup than in summer without realizing it.
good luck
Mike
