Hi guys.

Just wondering if the rs200 uses special cooling fluid? Last week the heating stopped working properly. Whenever I went up hill and drove it hard, the heating was great, but when I go downhill, and stop revving so much and the engine cools down, it goes really cold again.

I asked the mech today and he said it was probably the thermostat. So he orderd one in to be fitted tommorow but I'm wondering if I can just use a 50/50 water antifreeze mix or have I got to buy the special coolant from Toyota?

The mech. doesn't know anything about the beams engine ( I've got the only one around here) so I thought I'd ask the experts here!

Cheers.
