3.5L Engine takes a long time to warm up

I'm coming from a 2.7l L4 4runner and this truck takes forever to warm up in the mornings.

This morning my truck was idling at 1k rpm for 5 minutes and the needle didn't lift up.

Is this engine this efficient on idle? Is it because I'm used to a big block 4 banger?

 

I don't think my thermostat is stuck open because when I start driving it rises half way and doesn't cool on the freeway.

 

More oil in the 6 than 4. Takes longer to warm up. My previous car was an E90 M3. That V8 took 9 freaking quarts. Took forever to warm up.

 

Mine gets a 30 to 60 second warmup, lots of heat from the heater in under 2 miles doing 25 to 35 MPH, depending on where I'm at. Are you using the heater or relying on the temp gauge?

I live in the U.P. of Michigan and according to the temp gauge it takes forever to get its full operating temp but its been pretty damn cold all winter. we'll see if its any different in the summer (if that ever happens up here)

 

I do enjoy when people 700 miles south of me complain about lack of summer

Snowmobiling must be awesome there too tho. I've heard lots about the UP

Worth a read, but I'm no expert in the matter.

 

What's the reason you're mentioning your truck is taking a long time to get to operating temp? Parked outside, not defrosting the windshield? Comparing this scenario between my '93 Toy and my '07 Civic, the Toy was miles ahead of the Civic. The Toy got 28-31 mpg, the Civic 39-40 mpg. If just wanting to get it totally warmed up why worry? Newer engines and oils only require a short run time to get a rollin if not aware. But, when changing anti-freeze, the '93 Toy PU was quick to change A-F, the Civic took forever to get the system flushed a few times, warming the coolant a few times to get the system to circulate fresh water.
My truck so far has been garaged except two nights when backpacking, Spring temps have been in the upper 20's if not close to freezing over night in NV and CA.

meh, it warms up just fine this past winter up here in the northern tier. but then again those heated seats warm up in like 15-20 seconds on high and the remote start negates those issues

 

I guess I have heated seats, guessing that's what that button on the dash is for. Has not been that cold since I got the truck in mid Feb.

If it's hard to hit running temp in the winter, most likely stuck thermostat. Iron blocks will take longer than aluminum, not sure what you have. I had both a 5.9 and 6.7 cummins. I could drive 20 miles to work before it warmed up during cold winter months.

 

Amsoil makes a cooling system boost additive. It helps the coolant absorb heat better. It heats the water faster and helps to dissipate the heat in the radiator quicker once the engine is at operating temperature. The system should take about 11oz. I just bought some but have not had a chance to add it to my cooling system I will probably add it at the same time that I change my gear box oils to amsoil 75w90 severe gear synthetic oils in the next week or two.

 

No it doesn't.

 

Diesels in general take longer to warm up because of the higher capacity cooling systems.

 

about 5k here now and have never had this issue.

 

Thank you OP for asking this question! I don't think this is as much of a warming up question as it is a high idle question. I had a 2015 Tacoma (have no clue why I got rid of it), and at startup in the morning it'd take about 30 secs for the idle to drop to ~600 RPM. This 2016 3.5 seems to take forever for the RPMs to drop. I usually start it up, let it run for about 30 seconds - 1 minute until I hear a slight variation in RPM (or some pump thingy farting), then go. The rest of the day the idle drops pretty fast at startup -- it's just the mornings (or maybe in cold air temp) where it seems the idle never goes down below 1000 RPM. I hope that makes sense.

Is this "normal". New engine with all kids of weird quirks so just wondering. Mine's been sitting in the shop for a week for a couple other issues so if this is NOT normal I'll ask about it. (though I'll probably be told it's a normal characteristic of the truck)

 

These trucks have an electronic heater/hybrid. I'm looking at the temp gauge. If I start the truck and let it idle 2 minutes, I have the drive it two miles before the needle goes the 1/4 in the temp gauge. My mornings are not relatively cold, 60F. I live in southern California.

 

I'm here for the same concern, about the high idle. I don't like a high idle for too long. It adds wear, wastes gas and relatively loud. I would like to know if this is "normal".

I have had this issue with other cars. What the problem on those cars was the throttle body was dirty. I would take the intake off and wipe it off with a rag dipped in throttle body cleaner. That would fix it.

This engine on the other hand cannot have had a dirty throttle body. I've been having this issue since I have had it new. Kinda feel like opening a ticket with Toyota at this point.

 

It quit freezing up north here in Plumas Co. over a week ago or more. Even then, I'd only idle my vehicles a minute or so, depends. Taking it easy the first mile or so. A high idle at start up is to get the catalytic converter heated up. It's not like the old days. Hope I'm not bringing up something you know already.
