What coolant to use after flushing the system?

Cliffs:

Lotus only recommends Havoline XLC, however Havoline XLC in europe is not the same as Havoline XLC in the USA (which has Dexcool). Dexcool is not recommended by anyone.

Lotus USA suggested people in the states use Peak Global Lifetime.

Its a toyota engine after all, thus toyota would recommend toyota red coolant (not sure if compatible with factory fill).

So unless you can get euro-Havoline XLC, take your pick between Toyota Red or Peak Global Lifetime.

I did a drain and refill with Peak Global Lifetime a couple of years ago, but last month decided to do a flush and refilled with toyota red. I was surprised at how long it took to get all the old coolant out of the system. Someone had a writeup on flushing the coolant out, and I thought I'd get most of it out in 3 or 4 drains. It took me 10 drains to get everything out, and I was using a small amount of positive pressure on the coolant tank to eek out as much extra coolant as possible.

Or Toyota pink coolant (part number 00272-SLLC2), which is pre-diluted. Toyota red (00272-1LLAC-01) must be mixed with distilled water.

Peak Global Life was the easiest to find that came up on the Ok list.

It is Global Lifetime and not Global Life correct? They are different.

I can no longer find Global Lifetime anymore.

Web site shows Life Time. I think it's all the same though.

Is Zerex GO5 not compatible?

Not sure if they are the same. The color is different.

I use currently the toyota red and premix 60% water with redline water wetter but I do have an all Al radiator

Peak Global all makes all models or Prestone all makes all models. Car was born with Halvoline coolant.. Don't put the toyota red stuff. I just changed mine.. Huge pain in the ass!!!! Get ready to spend half a day bleeding the coolant.

Got an Airlift vacuum coolant filler. Does that help?

Why not? Asked my local dealer who said that is what they use.

Like you would not believe. I would never do a flush and replacement without it.

You shouldn't go to that dealership then. Lotus put halvoline into the car from the start..

Lotus recommends Peak Global not red coolant. The dealerships should take notice.

I don't know how you could recommend against the toyota red. Its a toyota engine and its what toyota recommends. If anyone knows the engine better than lotus, its toyota! I didn't know if it was compatible with the factory stuff, so I replaced it all. What good is the factory fill if you can't get it conveniently over here?

It would have taken me a lot longer if not for the airlift. I can do a drain/refill in less than 45 minutes with it. The problem is that you need to put enough heat into the coolant such that the tstat opens up and it circulates everywhere. I'd let it go 90 minutes before doing another drain so I didn't risk burning myself.

And what is the capacity of the system? The owners manual says quantity required @ 50% is 6 liters. Does that mean 6 liters coolant plus 6 liters water and it holds 12 liters total?

Also depends on your weather and use. Here in Florida and it is not daily driven I was instructed from Phil at BoE to use distilled water and water wetter.

Anybody know if Porsche Coolant would work ok?
