'22 3.5 takes a long time to get up to temp

What are cabin heat settings when vehicle warming up? If temperature is set high, fan on higher speed and very cold outside temperatures smaller displacement gas engines often don't produce enough heat to warm up engine and provide cabin heat. I have owned cars with smaller engines that you could cool engine from normal operating temperature to cold by varying cabin heater fan speed. Can be remedied by running cabin heat in recirc mode and a lower fan setting until engine warms up sufficiently and then you can blast the heat.

 

I had an 81 Corvette and in the winter months during a 5 mile all freeway drive home (no idling) it would never get up to normal operating temperature. My Tacoma seems to warm up faster than the Vette.

 

Your Tacoma may have the auxillary electric heater. You need to set HVAC temp to HI, and after a minute you should feel lukewarm air out of the vents, then warm air out of the vents after a few minutes, even if the engine is still cold.

 

Nothing new there. I'm up here in new england and have had some cold days with my 2020 v6 tacoma. Your right,it takes forever for these trucks to fully warmup. I had a gen1 tundra that did in 1/2 the time on the coldest days. I've complained to my dealer last year....its perfectly normal i was told, and not to get excited. I'll tell you my temp gauge even drops from mid way when full warm when at a stop light to 1/3 warm until i get under way picking up rpm. I'm even thinking off installing a grill cover to help.

 

My '17 TRD-OR, Automatic takes too long to warm up as well. I've got only a 6 mile commute to work, and the temp gauge doesn't move until I'm 3-4 miles into the drive. If/when I do remote start it and let it idle for about 6-8 minutes, the gauge will have moved a bit by the time I get into the truck, but there's still no noticeable heat being produced. I figured it was just a design quirk of the 3.5 engine.

 

Fluid flim for the gas door hinge is even better. I haven't had to lubricate mine in over a year.

 

I like the stuck thermostat idea, my 3.5 has no trouble warming up and staying warm even on -0 degree weather. The thermostat should completely cut off the radiator until it opens at 180 degrees and close if coolant temp drops bellow that. Not having a defroster is a safety issue and should be fixed by the dealership. Even in cold weather my temp gauge is moving towards the middle in the first 3 or 4 minutes of driving, and at temp by 6, and gloves off by 10.

 

I figured that stuff was really messy on paint, is it?

 

messy yes, but it is also way better then rust. The thing to remember is that most spray on lubricants evaporate over time, meaning you need to reapply them. Fluid film isn't meant to lubricate, its a rust prevention compound and doesn't evaporate.

 

That's another thing, I forgot that my state checks for defroster functionality. Mine is the same as yours, heats up honestly quicker than any other vehicle I've owned. The good ol 1995 Suburban that I drive when I'm home visiting family takes almost the first mile to get heat.

 

I found this bit online regarding the 3.5 engine. Not sure if it’s true, but mine also heats up pretty fast.

 

Its not a problem with the truck not producing any heat...theres plenty of it once the engine fully warms up. The issue is the length of time it take for this. I've owned vehicles that developed a bad thermostat...engine drinks excessive fuel and never throws heat. This is not the problem with this v6 truck. I gotta believe its a design one.

 

My understanding is that a lot of modern engines use the heat they produce on startup to get the emissions systems (catalytic converters) up to temperature first before anything else.

With respect to warm up times, I've got a 2022 and live in Canada with usually a few weeks of -30 to -40F. On these days, I plug my trucks block heater in and I let the truck idle for 10 minutes with the fan on 2-3 bars on defrost or defrost feet. I find it takes about 5-10 minutes of driving after warm-up on these days to warm up to the middle of the temperature gauge (with the fan on 2-3 bars the whole time). I find that if I change the fan settings to maximum too soon, it takes forever to get up to temperature.

 

Yeah I should've mentioned that in spite of the lengthy warm up my truck has always had, once it's at operating temp the heater can damn near burn my hand if I point the vent at the steering wheel, regardless of outside temps. I have never really noticed a big bump in vent air temp at cold start from an auxillary heater so I just drive the truck, teeth chattering lol

 

yup. Picked up a new 2022 Tacoma V6 in November. Takes forever for it to warm up. Dealer said that it was normal. well....I call BS. Picked up the 2022 after having a 2006 Tacoma. The 4L 2006 warmed up right away. Now I am sad I sold it. So.. my 2022 has basically the same fuel economy as my old 2006 since it takes forever to warm up to proper operating temperature. Gonna yank the thermostat and test it. We'll see what happens. Plus when it is so cold for so long, it seems to be trying to find the proper gear to be in. Cold transmission I presume. Whatever. grrrrrr.

 

The 3.5 is cold-blooded. The upside is they put an electric assist cabin heater in them. Turn the temp to high on defrost and full fan. It does help for cabin heat. My experience with mine is it got better after it broke in with MPG's. I had a 13 trd sport 4.0 and it warmed up faster also but it can't keep up with the 3.5 when it came to MPG's. Hope this helps.
