Does your 5th gen. take 20 minutes to warm up?

[Jeremy556]

Those of you that say it takes a long time to heat up, do you have the temperature control set to the hottest position? There is an electric heating strip that I am guessing only operates in that position.

Mine seems to be pretty warm after about 10 mins, when its -20*c, obviously depending on outside temp that changes, takes maybe 15-20 in -30*c, doesn't take long at all in above 0*c temps. (our 0*c is your 32*f)

Same here, takes about 10 minutes to warm up if temp outside is around -20 C. Good thing is I have remote start

Can't find anything on the 4Runner but it is on the 2012 on up RAV4.

Testing this morning after reading the post. 15 degrees outside but I do park in my garage (maybe 45-50 degrees). Took about 5 minutes to warm up. I will say my heat warmed up much sooner than the generic gauge reached operating temp...

Greg, just for grins do the same test in the wifey's Honda.

Alright, I took one for the team this morning. Read on:

Conditions: 30 degrees F and Cloudy.
Time: 6:50 AM EST
Location: Driveway where test vehicle had set all night.
Equipment: 2015 Toyota 4Runner SR5, DMM, Old Fluke Temp Probe, Casio G-Shock Watch With Stopwatch, Pad and Pencil, Me.
Set Up:
1. Seat Heater "OFF",
2. Used small piece of folded paper to wedge probe approx. 1/2" into the left center upper vent. Probe not touching anything.
3. Temperature set on "HIGH," all vents including rears left fully open.
4. Left outside vent, left center vent and right center vent pointed at my face.
5. Started truck and let idle at around 1200 rpm. Did not ever hit accelerator.
6. Climbed in to test.
7. Wearing only jeans and sweatshirt so no heavy jacket or gloves.

The Test:
1st Number=Time (minutes) 2nd Number=Temp (degrees F rounded to whole number)
0- 30
1- 31
2- 45
3- 51
4- 73
5- 80

Now this is the temperature on the probe inside of the vent. By around 4:00 I could "feel" the temperature start to rise around me. I removed the probe after the 5:00 mark because I had now measured and documented the temperature rise. I then decided to measure the air temperature around my head so at the 6:30 mark around 6" from my head the air temperature was 72 degrees F. At the 9:15 mark I needed to turn the temperature on the control down because it was getting uncomfortable.

What does this mean? Well, it means nothing really except one person has documented a changing condition instead of just getting on a message board saying "It's too HOT" or "It's too COLD" or "It takes too LONG" or "It's too HEAVY" or "It's too SLOW."
What is comfortable to me might be cold or hot to you guys. If you are like my wife then there is no correct temperature ever.
Anyway, it's documented now. To summarize after 5:00 minutes it's pretty comfortable in the cabin at idle and 30 degrees F ambient.

If you don't believe me fine. You go out in your driveway and go through a test similar to mine and we can compare notes. If you don't want to do that? Then I will call BS.

[MENTION=66316]1engineer[/MENTION] My LE heater works a bit differently when set to Auto (Dual). But my numbers come out pretty close to yours. My rig was garaged overnight, and the dash external temp read 43-degrees. I set both driver and passenger temps to 74-degrees, started the engine and waited for the heating fan to turn on. With Auto, the fan doesn't kick in until the vehicle is warm enough. (And yes, I did back the rig out of the garage and into the driveway. I try not to be that stoopid.)

At minute 4:15, the fan kicked on to 1 bar (lowest setting), and began blowing air. At 5:00, the fan kicked up to 2 bars. And at 5:45, the fan kicked up to 3 bars), which is the normal fan speed.

In other words, my heater didn't blow the 51-degree/3-minute air, but did start up when it could circulate 60-70 (?) degree air.

Hey, when you have a manual climate control you have to take the good with the bad...
Nothing like having it be 30 degrees (calm air) in the truck when you can have 30 degree winds blowing at you from the vent. Told you I took one for the team.

So can we call BS on the 20 minute crap?

Full disclosure:
If I were a good little engineer I would have tested this out using different ambient temperatures. Two days ago it was 0 degrees F here. Yesterday it was 14 degrees F. Right now it is 48 degrees F.
I then could have plotted time to heat up to 70 degrees at a specific point in the cab versus ambient temperature to give a clear picture of our climate control system.
Surprised some of you didn't pick up on that. I'm disappointed in you guys.

Results: My test revealed that I was a MAN

Greg, just for grins do the same test in the wifey's Honda.

This is the closest I had on-hand.

Main issue is I missed a merge in the 4Runner at 200 seconds. So, instead of accelerating to 65 and staying there, I missed the merge lane and hit a light (~250s) and got on at the next merge at 330 seconds. I'll have to try again soon since all of the other vehicles have the exact same route/speed.

I just moved from a FJC to my 2010 4Runner and the 4Runner takes a lot longer to warm up for sure. That FJ produces heat ASAP.

I decided not to mention it .... I was afraid your head would :boom:

well during the -20F cold snap we had end of December and some days in January, never had an issue with not having a overly warm interior running the remote start for 15-25mins.

before the remote start, never took longer than 2-3 miles from work door to warm up to temp (engine) and get decent warm air out of the vents @ 30 mph.

and the above only takes about 10-15 mins.

 

[Matteblack]

YES. Mine takes a long time until the cabin heat can be felt AND in the summer it seems to take a long time for the AC to cool the cabin. I've gotten used to it but it bugged me when I first got it.

 

[jrandom]

Mine is always making warm air within >5 minutes when temps are between 5-20F.

For all those that need to be insta-gratificated... espar hydronic on a timer : :tongue:

 

[NoDak]

the perfect setup would be the insta heater in the lexus cold weather package. its just a electric heating element to boost the heat output until the engine warms up.

 

[fatbacks]

Use the recirculate function - heats way faster.

I live in Alaska and it doesn't seem too bad, although I am coming from a diesel truck.

I just make sure it is blowing both floor and face vents - then turn on the recirculate button. Makes a huge difference. Fogs up eventually and you have to toggle between defrost and recirculate a few times.

If all else fails get one of these. Had one on my old truck and it was awesome. I think they have a gasoline variant.
