1. Jack up car on all fours.
2. Take off lower access panel in front and rear.
3. Open the drain from the block. Catch coolant.
4. Take off the driver's side coolant hose. Catch coolant.
5. Reattach hose and close block.
6. Attach airlift tool and refill with distilled water.
7. Start car and get coolant up to temp(takes a while).
8. Turn on heater to max to cycle the core. Temp readings should be 200f+ before the heater is turned on.
8. Repeat above steps twice with distilled water.
9. Fill with coolant.
10. Done.

I would not make a special effort to change the fluid. People leave this coolant in toyotas for 300k with no problems. If you were upgrading your radiator or removing the coolant U then I would change it.

Bleeding the air out of this car is not that difficult. The technique I used is to fill it, Run it and while its still cold put your mouth on the reservoir and blow into it. put your finger over the overflow hose of the tank to plug it. This is used by a few lotus specific companies I spoke with. Sounds crude but it works quickly.

I used the help of a wet and dry shop vac when i did mine. I used it to help get all the old coolant out and to help burp the system when done

I try and avoid putting my mouth on toxic chemical reservoir's. ;)
That's NOT what she said!

Anyway, I use the 'caveman blowdown' method too. But I take a scrap of plastic sheet and cut a small X in the center. Put that over the reservoir opening and blow through it. Avoids the dain bramage and makes short work of getting *most* of the air out. Then I go for a short drive and burp a little air out at the front bleed valve. Job's done.

Cool. Could you provide details on this procedure?

I raised the rear a little higher and found out it was easier that way for the refill.
that's what I did as well... maybe took 20 minutes for the car to warm up & open the t-stat from a cold start & burped pretty much immediately after that...

i got a little nervous after reading some of the hassle stories about flushing coolant on these, but it couldn't have gone much easier for me :shrug:

Okay I just refilled my coolant. The coolant tank did not empty when fans when in high.

I found this thread, and was going to blow down the tank with my mouth, with the tank covered with plastic, but decided to use the exhaust of my shopvac. I disconnected it from the bucket, so it was sucking clean air. I only turned it on for 1 second and the coolant started to drain.

I started it up and coolant started to flow into the radiator. I was able to add 2 gallons of coolant. Coolant started to surge in and out of the tank. I shut it.

After closing and driving it around, I let it cool off opened it and had to add about 1/2 gallon.
