Hi

The trouble is i have no coolant in it and the nearest hill is quite a way from here. Can you bleed it with the heaters on, and on a flat surface?

can you put the front up on the kerb that will be high enough...and remember fill the radiator and the expansion bottle and keep an eye on the radiator also put the heaters on full up too full temp and direct the air to the screen(keep an eye on the temp guage) also get yourself some toyota coolant.once you have heat coming through the vents let the car cool and then check your levels,job done. good luck matey if you get stuck just give me a pm.

You don't need a step incline just enough to make to radiator filler neck the highest point in the system. To help you can use a empty coke bottle to raise the highest point even more. Fill the said bottle with water then place neck down into the radiator with the vehicle running. You'll see the air bubbles rise into the bottle & the water level drop as the air is replaced with water.
