Hey,

Just wondering what everyone thinks is the best method to warming up your skyline before you start driving and cooling it down afterwoods.

I have been given mixed information and just trying to clarify what is the correct one.

Is it better to let the car warm up and cool down while it is parked ie: about 5 mins of running or would it be better to let it warm parked for about 60 secs then drive it normally for about 15 mins at around 3000rpms?

any information is appreciated!

thanks

:D

you could be anal retentive and do both!! like so many others do... but realisticly giv it a couple minutes to warm up and treat it with respect for a bit.

when it comes to cooling it down, just set the timer according to how hard u drove it. for example if u thumped it on the way home give it 4 min to cool down, but if u cruised it home give it 2 min to cool down

dont be one of those shmucks that gives it 10 mins to warm up before you drive it

Cold morning I tend to warm it up until the needle on my oil temp gauge just starts to creep up, otherwise I'll warm her up just until the water temp needle starts to move north.

Cooling doon... Turbo timer my friend. Anywhere between 2 min to 5 min, depends on how much spirited driving I've just done beforehand. :D

For warming her up, I usually give it until the water temp needle begins to creep up. And for cooling down, I usually slow down a couple blocks before home so I don't have to leave it on the timer for more than a minute or so.

Edited by Remix-

The engine will warm up quicker if you drive the car. And you might as well be getting somewhere while you're burning all that fuel. I climb in the car, fire up the engine, reverse out the driveway and on my way. Keep it under about 3000 rpm until the needle starts to move.

Cooling down - forget timers; the best timer is inside your head. Just drive sensibly for the last 1km or so before you reach your destination, and you can pretty safely simply switch off the engine.

when im about to leave, before i get ready i go out to my car, turn it on then take the key out so the turbo timer takes over then set it to 4-5min, lock the car then go and get ready.

by the time im back the car is reasonably warm and is at a decent temperature for me to drive off with my mind at ease.

Warming up, I usually start the engine as soon as I get to the car.

Then if I have anything to load into it, I'll put it in. Get in the car, put the belt on and make sure everything's right (checking mirrors, gauges, etc) before slowly driving off. Usually around 30-60 seconds.

As blind_elk says, your engine will warm up faster if its got load. So I'll drive it around gently until the water temp gauge increases.

Don't forget, your water temp gauge doesn't tell you everything. You still have no indication of how hot the engine oil is, not to mention transmission and diff fluid, tyre temps, and the rest. Half of them won't even get heat until you start moving.

As for cooling down, I don't drive a turbo but like all modern engines mine runs hot. I prefer to cool down on the move. In the last few minutes I'll drive it at low load; luckily its downhill to my place so I tend to just coast in a high gear.

Leaving your engine idling when you pull over is great for passing oil through your turbo to help cool it down, but with no air flow over your heat exchangers....where does that heat end up? Its not going to dissipate itself.

I used to be a paranoid freak and let it warm up for 10 minutes or more and even then the temps had only just started to move up. Couldnt figure why I had such bad economy.

These days, I fire it up, wait till oil pressure rises (few seconds) and take off driving sensibly. Funny now that it doesnt take anywhere near ten minutes to get up to temp.

Cool down is like others said. Just take it slowly 5-10 minutes away from home and then I shut it down instantly.

I jump in and drive straight away, but like blind elk, keep RPM low (I try to stay below 2,500) and dont come on boost until the opperating temp is at normal, and the oil pressure is about normal too. At least the oil pressure should give you some indication weather the car is at normal opperating temp.

Cool down is similar to blind elk too but if I've been boosting at all I usually give it min 1 min just for peace of mind. Hard driving, maybe 3-4

Not sure what other people do but thats just my habit now.

thanks heaps for all of your input!

i thought the letting it idle for about 60 sec then driving it under 3000rpms would be better for it as far as lubrication and stuff goes then just letting it sit for 5-10mins!!

thanks :woot:

words to live by

Do also remember the cool down isn't as critical in water cooled turbo's due to thermosyphoning. :woot:

I do as the majority.

Warm up - Start, put the belt on and drive off easily 2000-2500rpm.

I was told to do this by my engine builder as doing this brings the forged pistons up to temp quicker reducing the amount of time they slap around damaging the bores.

Cool down - drive easy for a km or two prior to shutting down, I'd be silly to thrash around the side streets where I live anyhow.

remote start is cool...

i start mine as i step out of the house in the mornings and by the time i've walked to the car stepped in and put on my belt, a good 60s have passed :whoops: then i just take it easy as everyone else does...

"Warming the car up" is mostly just a habit that people have picked up from previous generations.

People saw dad warming the old FJ up for 10 to 15 minutes, and they think that's just the way things are done.

Welcome to the 21st century people.

You are now able to get into your car and drive off straight away.

remote start compromises the security of the car, I read a post sumthing abt it sumwhere, not because the car is running without a driver, got to do with lesser alarm function..I think..

me, I warm up till temp needle goes to middle, abt 5-6 min...

Well in my bro's car you still need a key to drive the car as the only thing that is working is the engine...

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
