Normally after a hard or long drive, once I pull my car into the garage, I'll lift the engine lid to help the motor cool off...am I insane thinking this will help the longevity of the motor and components??

YES!

 

After I open the engine lid, I turn on a big box fan and let it blow on the motor..... <img src="graemlins/xyxwave.gif" border="0" alt="[bigbye]" />

 

I have gone the natural route with a pack of St. Bernard dogs who just pant heavily over the rear of the car. Occasionally when it gets really hot in the south, I feed them ice cubes first. <img src="graemlins/icon501.gif" border="0" alt="[icon501]" />

 

I use a high pressure hose to keep my engine cool and clean after a hard drive!

Doesn't everyone have air conditioned garages? I just turn up the AC and bring the car a tall glass of Mobile 1.

High,
why not just put the spoiler up manually? I think it helps. If excess heat doesn't escape it still probablly increases airflow from breezes over the top and out the left wheel well.

 

Hi,
if I'm right; lifting the engine lid for a long time will drain the battery because the engine light comes on, so it's better to open up the spoiler.
That's what I do.

I wouldn/t be concerned about hot run problems rather than cold run problems. You are trying to address the wrong issue here.

 

The cars are tested in Death valley, and near the northpole, so Porsche knows how hot and how cold the cars could go before damage something, right??

And second, colling off a engine in a fast way is wrong, it gives to much tensions on the materials.

I agree with Arjan. Letting the motor cool slowly is probably the best. Quick swings in temperature never helps any material.

 

Sorry, I meant cold start problems.

 

Hello

Engines love that you heat them up and you coll them down after you runed them hot. Stoping a hot engine is streesing the unit and even lifting the enginelid will not help very much.

best is to use the enginesided cooling devices to bring the temperature down. Normaly some 5 minutes medium slow driving bring temps down and if not use the lowest gear and highest rev to get cool.

Even if it WAS a good idea, I don't think it helps much - I never seem to get much heat coming upwards from the engine - it's all leaving sideways, via the wheel-arches - I'm always surprised how little air disturbance there is above the engine lid when the engine's really hot and I'm just stood back, admiring the view.
I suppose the undertray (where still fitted!) prevents a lot of upward flow of air.

And do you guys know what those boys do up there at Lapland (in Finland, whee Santa lives) in winter tests?

In the morning (when it can be below -30 Celsius), cars sit outside, they'll start them, step on the throttle (in neutral) and let it scream! <img src="graemlins/crying.gif" border="0" alt="[crying]" />
