^^are you being serious?

Upon starting I let it warm up for maybe 20 seconds. The higher rev at start up is probably the automatic choke, which isn’t really necessary in warmer weather. If I leave the car stationary, after a 1 min or so it will idle correctly, between 600 and 700rpm, however if I drive it after the 20 seconds, by the time I reverse off my drive it is fine, idling correctly. However, until the engine is up to running temperature I will not exceed 3500rpm, and that’s me being aggressive!

The cool down to me is BS. Besides wasting petrol, how can leaving a stationary car in 90 degree weather help it? There is zero air flow into the engine, so the fan will have to engage to cool the engine. Personally, the best way to cool it down in my mind is to stop the internal combustion!

I consider warm up more important than cool down.

would have been great if our cars came with an indicator on the tech ala E46 M3 where it shows how well the motor is warmed up and at what rpms is safe to exceed....i thought this was a great feature for high rev engines.

I'm no tech, but that seems to achieve the opposite results of what a cool down is intended to do. Think about it this way; if you run 5 miles, then stop all of a sudden and try to recover, you'll be in a lot more pain than if you paced way down to almost a walk and recovered that way. For your car, the cool down lets it cool itself down evenly without any rapid changes in temperature in various parts that are stressed during driving.

I live in a very hot climate, so warming up is not a big issue. I just wait until the RPM settles at 650rpm which is the normal idling speed according to te owners manual. This takes 2 minutes max.

However cool down is necessary only if you have driven hard and you plan to stop. I usualy turn of the AC and drive at a constant speed for about 5minutes. I don't feel that this is necessary for a non-turbo engine, but hey, anything that keeps me in the G for longer is good excuse for me.

I also read somewhere that if you want to cool your car's engine down more quickly, turn your fan to heat (Full blast), turn off the AC button. This will draw the hot air from the engine bay into the passenger compartment.

PhilH930

This is true, although can be somewhat painful on a hot summers day. On two seperate occasions, two cars in England over heated on me and the only way I could bring the engine temp down was running the heat at max, with all the windows down etc. Neither place was it convenient for me to stop, and with this technique you could actually see the temperature gauge drop to normal safe/normal levels.

Warm up for a minute or two. Feels weird driving the car on a cold start when the RPM's are high.

You're right. We took a road trip to Arizona once and it was at least 120 outside. Using the A/C was impossible since the car would overheat, so whenever the temperature gauge would reach the "H" (which would happen every 10 minutes or so), we'd blast the heater to cool the engine down.

Remember, every min. of Idol= 1/2 mile wasted. I was always told if you are using synthetic, the time it takes you to put your seatbelt on, take your sun glasses out of the case and put them on, and find a good song on your ipod. Than drive it out of your neighbor hood (at the speed limit and not flooring it) Your car is ready to go by the time you hit the freeway. I also live in California, so thats a big factor in that statement.

they put a device in cars to regulate and control warmup, its called a thermostat.
As long as you dont start it up then start redlining it right afterwards, no sitting and warmup is needed. Turn it on, put seatbelt on and drive off.

lol, why would i be lying? is there anything wrong with my method?

humans and cars are two different things.

i do not see anything being harmful with me popping the hood after i finish with driving it. it just let the hot air out of the engine bay.

GiGGaplease

i will try this now instead of popping the hood. however, i be sweating bullets after though.

pass1over

nope, none at all. I do the same thing when im done driving my mustang.

GiGGaplease

oh, i thought i was the only one doing this retarded method. oh well, no harm, no foul.

pass1over

also gives me a chance to do a visual once-over of the engine after im done. But its a totally different animal than my G.

The only time I do a "cool down" is when I have been running the air for a while, I like to either turn the air off while I am pullin in or turn it off and wait like 30-60 seconds before shutting it off. I do this because on the G35 the AC would produce moisture that would get in the in cabin air filter and cause the car to have a mildew smell. If you let it run without the air on the engine heat would dry the moisture.
