5) Replace the evaporator, capillary tube thermostat with an electronic version - prevents evaporator freezing
6) Make sure that the coolant system is bled properly. Saved me 10 degrees of coolant temperature; coolant which circulates around the cabin. Add water wetter to the coolant. Your temp should be under 200 degrees most of the time. I live in Texas. The temp stays about 194.
7) Consider bypassing the heater core. You can cut and splice, or you can install a switchable system. Search for "heater bypass". Well worth doing.

I found the same thing here in Florida even in my yellow car, and it is parked outside all the time, but there are 3 partial cures.
1) A car cover, a cheap Tyvek from Walmart works best at reflecting the heat.
2) Reflector in the windshield, but does not stop heat entering elseware.
3) Tinting every window with 3M Crystalline, no other tint compares.

I think I've put less then 100 miles on the car since summer began here. It's simply unbearable (my car is black) once it's been out in the sun for longer then an hour.

If you're tougher then me and don't mind arriving to meetings drenched in sweat then it's definitely possible to drive it year round

Isn't there a factory option for $500 to delete the A/C? I live outside New Orleans and I can't drive it to work due to arriving sweaty. I really think it struggles in two departments.

1. High humid areas
2. Doesn't blow a high volume of cold air

I used a 1/8" self adhesive duct insulation, and then re-trimed with a microfiber. I will provide detailed info if anyone considers doing the same.

I live in houston and I find the air conditioning to be adaquate but just barely. On really hot summer afternoons the cabin temp is a bit high but bareable. If the outside temp is less than around 98 the unit works completely fine....

Seriously, my car is small

I used black Duck Tape over the vents, photo is pre-tape (credit to "Zammy1").
Drilled out bottom two pop rivets on air intake cover and bent it up.

I have read very little on the subject but havent been able to get a clear picture in order to make a dessicion.

can anyone tell me if the cars A/C is up to the task in the Miami summer?

...BTW this would be my daly driver.
I have had mine for 3 years and lets say the A/C is somewhat sub-par. I installed the heater core bypass and that helped a lot. I live in Houston, so same type of weather. It really works very good in town, but long trips in the heat at highway speeds it tends to freeze up. I still love the car.

TheViper is right about 3M Crystalline. After three years of the Colorado sun, I finally decided to add it, right before our 100 degree weekend. What a difference. Plus, it greatly reduces the laser-like glare off the front fenders when they catch the sun just right.

The shop that did it had two 3M installers out here for a month from SoCal. They were very well-versed in the Lotus. I knew right away my installer was for California when he said "Lotus...dude...your windshield's got GAME"

thanks for the pics.

i was driving the car from a track outing and had the a/c on high but it just wasn't enough. the i touched the dash and it was damn hot from the sun. something has to be done to lessen heat coming in.

i was already thinking of 3M crystalline.

From my before and after tests, Crystalline reduced the temperature inside the cockpit by 25'

I like the side insulation thing you did, looks good too.
As to the new “evaporator capillary tub thermostat” to a electronic version? Can you expand on what you did and brand of parts and all(part #, where you got it)

I know mine is freezing up, probably a big snowball in there.

Just thought I'd take this opportunity to state that my A/C works BEAUTIFULLY and keeps me really cold. First time I used it all year and it was oh so sweet.....

The 3M crystalline is clear -- correct? So, do you apply this stuff to the front windshield as well? If so, can you clean the gunge that builds up on the inside of the windshield without scratching the finish?

I had 3 installers here in Austin tell me it is against the law to install any window film on the front windshield, clear or not. Also, what to do with the registration/inspection/Hippie Hollow stickers?

The single, absolute, best foolproof mod I did to take care of the AC problem was... to move out of Florida to a cooler climate!

Night and day difference. Driving the Elise in 90+ South Florida summer heat in traffic on flat, boring, straight roads is not exactly the best place to drive an Elise.

One version of Crystalline is considered clear, 70%. Believe it or not, there is very little difference in heat rejection between the versions. It made a huge difference to the comfort level in the cockpit. Don't confuse Crystalline with any other tint, there is nothing else like it and the price reflects that. One problem is in finding an installer who is capable of doing the windshield.
