Garage is hot

My garage is extremely hot. Our car's heat after running make the situation even worse. I have wooden doors and was considering replacing them with some sort of insulated doors or would placing some sort of exhaust fan work better??
TIA

If the garage gets the afternoon setting sun, nothing much will probably help. I have insulated doors but it still gets pretty hot in hot weather. I don't think engine he affects it much though.

Insulated doors would reduce conduction of heat, and might even bring you into compliance with fire-code ;). Ventilation would help, if it means bringing in cooler air to replace warmer. Depending on just how hot it is, a packaged attic ventilator fan with t-stat might work; you'd need adequate in- and out-flow areas to suit fan, of course. Your local building inspector could give you info as to what would be acceptable in your city/town.
Also, insulating the garage exterior might help.

DK, I found this website about ventilating spaces. http://www.airvent.com/homeowner/whyVent/whyVent.shtml
For the most part, it says to install soffit vents (vents under you eeaves) then you can install a fan to place over your gabled vent. If you dont put in the proper vents, you dont get good exchange throughout your garage. J

Attached ? Finished ceiling ? Put in a couple of top hung "push out style" windows on opposite walls. Detached ? Open ceiling ? Go with vents up in the peak(s) and a window.
A friend has a CMU home/dbl. garage in Tucson with no side door or windows. It sure is DARK and the temp in there gets up above 130 oF in Summer ! Not the way I'd build it.

I suppose you could let the car cool off before you put it in the garage.
Not that I'm sure how big a factor this is.

heat problems I ever encountered was from the tires "melting" or softening the vinyl floor tiles...
One of my garages has neither heat nor a/c...and its really not that hot inside with a window open on both sides and a simple window fan sucking air thru the garage..plus a thermostat controlled fan in the rafters...

Insulated doors keep heat in. They are good for an attached garage to retain heat in winter, or for a detached if you want to sometimes run a heater to work out there.
To remove heat, vents or windows is best. Not knowing the construction, I can't say exactly what to do.

A fan will work well provided there is some kind of cross-ventilation. I installed a house fan in my garage ceiling, wired to a wall timer switch. I open the side door which has a screen door and turn on the fan. This moves the hot air out of the garage plus cools the attic space. Works great. I doubt an insulated will do much, plus it won't take out typical toxic garage fumes. Consider planting a shade tree on the south or west side of your garage.

Newsflash: there's more than one way to make a garage. Does it have a roof? Is it in a cave? Under a skyscraper? Under second floor finished bedrooms?
If it has an unfinished roof, as is the case with many garages, install a temperature controlled attic fan.
