How long is the norm for a 22re to warm up to normal operating temperature? On my truck in 90 degree weather with the ac off it takes over 20 minutes to warm up, I can't imagine how long it is going to take when it is cold outside.
it should not take that long to do so. try getting all the air out of the coolant system. cold start is judged by the temperature of the system, and the sensor is not in the brightest place. low on coolant and it'll have to wait for the whole entire block around it to heat up and "heat" the sensor. the coolant's temperature also controls the cold start idle. when when it'll control the idle air. i think it lets less through, something like that. if you ever wondered about the coolant line under the throttlebody lol there's a cold start injector on the manifold, could be dirty. I'm unsure, but i'd hate for that btchn thing to be stuck open.... lol anyway, cold start loop kills mpg. i hate it, even in winter. especially that automatic OD lock out
I know im not low on coolant cause my reservoir is in between full and low when it is off and it goes up to full when it is warm. I also just replaced the coolant temp sensor so maybe the cold start injector is dirty.
alright then. Coolant question - Are you running Toyota red coolant? Hopefully the system doesn't have scale and rust and all that in there. That stuff could potentially cover the sensor. I'd also give it a look over and try to "burp" the system out of air. Drive it on an incline (say a driveway or something) and just park it there, open up the cap and see if it "airs out". I'm not sure what else would cause such a prolonged "cold start" My truck in 90 weather is noticable when i start up. Engine is already warm from the surrounding temperature. It will start up, the idle is sort of high, then you can hear it drop. In winter... very noticable. But takes forever to warm up when it's sitting there. I give it about 30seconds to a minute to circulate some oil, maybe a little more, depending if i'm snowed in or not. Then I will drive. Once I establish oil circulation, I'll slowly drive and it'll warm up much faster. on my temperature gauge, regular driving in 70 degree weather barely goes past the 1/8th mark. regular driving in 80-90+ degree weather usually touches the 1/8th mark and past it. MAYBE 1/4th if i'm in traffic. or i'm on the highway, it'll touch 1/4th mark. And If I use A/C.... it'll touch the 1/2th mark, usually when i'm in traffic or highway driving. In winter..... geez, I rarely get to the 1/8th mark, the radiator is too good... for winter. I'll drive about 2-3 miles halfway to school and finally the heater jumps in. That's how my temperature gauge reads. When you hit 20 minutes, is that when the idle drops or when you get a temperature reading on the gauge?
I'm sure it will be fine if you just give it a few mins to warm up everytime you start it. And a bit longer in the winter. It's always like that with an old vehicle. Where as a new vehicle it's almost better to just start it and go. When it hits 0 degrees Celsius (about 30 F) on a cold winter morning I usually give it a good 15 mins to let my truck warm up. I hate having to wait for the heater to come on!
Ya i will have to try to burp it. No im using normal coolant that you get at the auto parts store. When the ac it heats up in like 15 mins. Thanks everyone for the help.
Maybe you want to check the coolant temp sensor. It tells the ecu to add more fuel during startup which is important because efi needs to get to operating temp. You could try this test: http://www.toyotanation.com/forum/showthread.php?t=262369
