#853 of 906 Cruze Eco Stick, long warm-up time???
Feb 03, 2012 (11:58 am)
I would like to know if everyone is having issues with cold engine warm-up time???? I installed my own fully functioning coolant temp gauge and at any temp below 45 degrees warm-up time is very long especially if you driving for fuel economy. Today I did a 2 minute warm-up all accesories on, headlite bright, fan on high defrost heater control to cold. Drove 5 miles hard acceloration up hill, turbo boost and it was still at 180 after 14 minutes. Front shutter was closed the entire time and electric thermostat was still closed when I returned???????.
I know that the engine is very efficient but quick warm-up is essential to fuel economy. 180 is not bad but specs call for 210 normal temp.
Second test in 20 degree temp was worse, no warm-up after 7 miles engine temp was still 170 with 3 people in the car.
I have installed a lower radiator hose coolant heater, it went bad after 5 uses, but it seemed to help if put on about 1/2 hour before I use the car. It did set trouble codes twice but not with any repeatability that I could see. Temp gauge would go to cold and check lite would be on and cooling fan running. Code set was for engine coolant temp sensor improper operation, but would only set about 4 miles into first trip ad then not every time. I had to clear codes with scan tool to restore everything to normal.
How long does it take for your car to warm up on gauge 1 tick before 1/2????
I expect automatics and standard models to heat up quicker because they waste more fuel.

i have 1.8L cruze stick and it warms up about the same as you are reporting, starting in an attached-garaged at 20F above outdoor temp. i don't care so much when it gets fully warmed up, only when it will start giving cabin heat on a frigid winter morning, and that it warms up 10x faster than VW TDI did !
maybe there is something funky with the Eco grille-flaps (?) - aren't there some closable flaps - like diesels use to block the radiator? on eco are they controlled by ECM? maybe they are a factor you can control or are malfunctioning? seems like they could affect coolant temp big time in winter.

About the grill shutter, I have a switch on the shutter to monitor when it closes, it is closed the entire time. Heat will start at about 160 degrees.
This morning I used lower hose heater, on 10 minutes started and idle 20 seconds, shut off and left it for another 10 minutes, my temp was at 150 1.5 miles out and at 4 miles was at 180 which is acceptable but I did not use the heater and I started at 38 degrees. This will do the job, I plan to remove heater and hose for warmer weather, already got a new hose ordered thru GM.
I am surprised that the 1.8L warms up so slow, not known for it's efficiency.
I think GM needs to offer an engine pre-heater for moderate to cold temps on all these smaller cars.

engine-block-heater is nifty option, I actually had one on an LG4 V8 - but it leaked after a few years - requiring freeze-plug-replacement !..
cool about the grill shutter. i was wondering what would happen if i took the eco grill shutter set up and put it onto the front of a 1.8L cruze. some sort of matter/antimatter implosion perhaps...
g-man, the distances you are mentioning still seem amazingly low for anything resembling full warmup. these cars warm up SUPER fast in my opinion, since I am measuring by cabin heat not coolant temp. I dump max heat into the cabin intentionally, as soon as the coolant gets any warmth at all. the item i wish for is a heated steering wheel...
possibly consider that the engine is NOT warmed up when the coolant reaches whatever temp you want, 180, 195, 210, whatever... it takes another 10 minutes for the block to warm to that temp, after the coolant, man!
On the VW TDIs, some folks would put a foam tube thing around the grille/airdam crossmember, to physically block some of the grille, and to allow the engine to retain heat in winter. I never tried that and don't recommend it for your Cruze! There were some mornings/days where I would drive TDI 75 mph for 25 minutes and it would never get fully warmed up.

car has been in shop 15 days now and supposedly they have received the heater core so it should be installed today. I should know by tomorrow at the latest what the outcome is.

Here's hoping it will be fixed, ken137 - best wishes .
#860 of 906 Minor Complaints...
Feb 18, 2012 (4:36 am)
Have had my LT for about a month now. Very pleased overall. Minor things are lack of interior trunk release, only one convenience outlet, no cargo net, strong smell from off-gassing of plastics, and no light in glove box. Get the turbo version. You won't regret it.
#861 of 906 Still liking it

2011 Cruze LT1 Turbo. Now 30,000 miles after 13 months. No complaints except periodic rattle from drivers' side pillar. Each time I take it to dealer the rattle disappears but some other times it sounds like a pop can is in there. Mileage decent not great at 29-30 MPG HWY, but I do drive pretty fast. I like the way it drives and find the cabin comfortable and decent quality. Backseat is more or less unfit for adult humans.

Took a trip down to Austin, TX Saturday from Frisco, TX ~ 4 hour drive all highway. Filled up the tank the night before and averaged 42.7 down and then 45.3 on the way back without resetting the gauge. My instant/50 mile average touched 50.0 at one point and I drove an average of 67.8 mph with highway speeds between 70-80mph. Absolutely love this car!
2012 ECO ~7650 miles
