Just to let you all know today my evo sat for 3 hours running with the a/c on in 90 degree florida weather. The temp gauge never budged. How did this happen you ask? I was dropping my 3 year old off at the babysitters when he decided to run back to my car and lock the doors and jump out. So im sittng there like a jack assssss locked out of my car. I then went to my house to try and find my lost extra set of keys. I tore apart my house cause i was pissed it now looks like my house was robbed. The keys are still lost. I called a lock smith and he said 30-45 minutes. 45 minutes later i call and he cancels so i call another lock smith. He finally gets there and i check the time. 3 hours had passed. I was prepared to break my car window if i saw even a hint of that temp gauge moving. Is there anything i should be worried about some co-workers said my catalytic converter?

 

My car has sat in 115 degree weather with A/C on for about 45 mins... no problem. Summer was too hot.

 

Can't you foul the plugs by letting it idle so long?

 

umm... Japanese cars never overheat..at least the new age ones. I cant say the same for american and european cars.

 

Thats some crazy crap. Glad to hear nothing was hurt on the car.

 

the plugs can load up on it, as too the cat from running so rich. Take the car out for some nice strong boosting runs and let the ignition burn off the excess carbon. If needed pull the plugs and check them, shouldn't be any worries at all.

 

Dude, why didn't you just call the Mitsu roadside service? Doesn't the service include Locked Out? I know it includes gas, changing flat tires, etc but I think it also includes Locked Out too. Correct me if I am wrong.

 

Dude that would suck, Glad to hear you didnt kill the little one for that.....I know some people would have gone ape ****.

 

The asians have figured out a way to eliminate thermostats that fail? What exactly is the cut-off date for "new age" vs "old age" Japanese vehicles?

j/k

 

As long as your fans are working you won't overheat your car. My racecar starts overheating if it sits on the grid for too long (no fan, too much weight ), the second the car starts moving forward and air gets pushed through the radiator then i'm all good.

 

I just do not see how this can be true - if that's the case, what's the point of the radiator at all? Some engines are air-cooled (original VW beetles, Katana motorcycles), but they're designed with air-flow paths for this very purpose. Our heads and engine block are designed to be liquid cooled.

When I was travelling on the highway at 75mph in my Ford Explorer, the thermostat stuck closed and it overheated fast. The fan was operational, and I had a lot of wind across the engine. Are you telling me it's because Ford doesn't have ancient JDM secrets built into their air-flow design?

 

I think that he means as long as you have a fan and your thermostat doesnt get stuck closed.

Fans provide airflow while car is stationary.

A thermostat stuck closed will not allow the transfer of coolant in engine. Does not matter how fast you drive.
