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

[buchaja]

Seriously, this is the slowest to warm vehicle I've ever owned. Just for comparison, I took my F-150 out and it produced heat within 5 minutes. It has the 5.4L V8. My Avalon, with the 3.0L warms up quickly too.

So, is your 4Runner as cold blooded as mine?

 

[oljedi11950]

YES my 05 doesn't take this long IDK what the deal is ? Maybe a different thermostat ?

My 2015 trail warms fairly quick. I live in Colorado. Now, Toyota is good at putting together parts based on region. How about a different thermostat, one for colder climates?

Can't really complain about it because it's only like 57*F at night here, but I have noticed that the 4runner is slow to heat, and that the air flow is not very powerful compared to my last two vehicles.
I had a Jeep Wrangler and a Nissan Frontier that both seemed to have almost instantaneous heat.

Yes, between the slow warm up and the anemic fan it's a pretty terrible winter car. I purchased an aftermarket heated seat kit which has helped but it's still cold!

My daily commute is mostly in town so I tend to keep in in select shift and 3rd gear which helps a bit.

I have a heated shop but when it is left outside it seems fairly normal. Our camry isn't so hot either.

I have a twenty minute drive to work. The first five minute or so suck. After ten minutes I generally start to warm up. I really, really miss the heated seats that were in my previous vehicle.

My 2014 SR5 takes 15-20 minutes in cold weather (30F and below) to warm up to full operating temperature. This is driving in heavy traffic through Cambridge MA. In comparison, my 2006 Honda Pilot warms up in half the time under the same conditions.

 

[adam2562]

YES!!!! even with remote start on for 12 minutes it's still cold!

Interesting you mentioned this, thought it was just my truck. Doesn't take 20 mins, then again I'm on the coast of calif, but unusually long. Heated seats aren't something I typically care about, or willing to pay extra for, but I'm thankful this truck has them.

What's odd is my old 2nd gen 4Runner immediatly warms up, is blowing strong heat from front and rear heaters before i get to the end of my block.

Makes you wonder if their still putting thermostats in these new engines.

 

[diverscale]

yes it takes long to warm up it cold temps here too, especially if you are not on the freeway doing 75MPH.

I think it might be caused by the front engine fan with that all-aluminium engine, losing heat by conduction. (?)

Warm-up time is very dependent on speed and engine load. So everyone will get different results depending on their routes, but I still consider it a slow warmup engine.

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)

I'm also in Calgary, park outside, and have absolutely no issue with heating the truck relative to other cars. One thing I do notice and like is that the seat heater produces some serious heat in around two minutes and keeps me going while the air warms up.

 

[Simonpk]

heated seats start working in less than a minute, but as I coast downhill, no load on engine, for the first 5 minutes on daily commute to work, heat takes around 7 minutes - but it's not that cold here maybe 25F to 35F in the mornings this time of year

 

[JET4]

My 07 4runner doesn't take no where near as long as my 11 does.

 

[3wbdriver]

You guys are starting to make me miss my unheated non air conditioned 72 Blazer. With the genuine, simulated, imitation vinyl seats that countless Naugas died to provide...... :violin:

Out of curiosity I tried digging up opening temp info on late model 4Runners from an online parts seller - dealer in Fla. None were provided.

For the '14 4Runner, they sell a tstat and tstat housing in one pkg. Seems you are unable to buy just the tstat.

This didn't really surprise me. I was looking into doing a cooling system tune-up on a 2010 6 cyl Dodge Charger the other day. They too sell a tstat with the tstat housing included. Can't buy just a tstat if sourcing from a Dodge dealer.

I don't think it's as much a thermostat issue as a software issue? (The 4th & 5th Gens both use 82°c thermostats)

For example there is an issue with 5.9L "#53" Cummins engines found in Dodge Rams in which when these blocks were cast there was a section that was too thin below the exhaust manifold. In cold weather the engine would warm up too quickly and the resulting uneven heat expansion cracked the block in a perfectly straight line at thin spot. The "Fix" to prevent cracks from occurring in the remaining unaffected blocks (something like 100,000 engines I believe) was to reflash the ECM with an updated software. The reflash change the warm-up strategy to warm up the block more evenly thus preventing the cracking (by reducing power until the vehicle was completely warm, so owners obviously complained about their trucks being gutless in cold weather after the flash.)

The point is that there may be a strategy to why it takes so long to heat up. Though with an aluminum block it shouldn't be as prone to uneven heating as cast iron blocks due to aluminum's nature. Not to mention from an emission's standpoint the ECM would want the vehicle in Closed Loop as soon as possible. Some of our vehicles used "heat switching valves" that essentially closed off the heater core so the engine could warm up faster (though I don't recall the 4th or 5th gen vehicles using these.)

Yep ^^ your the man !!

It is slow to warm up. Probably the slowest vehicle I have ever owned. Not a big deal where I live. I wish the climate control fan was a little stronger in the summer, but it gets the job done.
