Cam Belt And Water Pump

[Steveenduro]

I figure that at 140,000 miles, and at 60,000 miles since the last cam belt change, I should change cam belt and water pump this weekend.

I've done the belt before, but not the water pump.

Do I need to drain the cooling system before pulling the water pump out, or will I just loose a bit of water?

I want to avoid draining really, as last time I couldn't get all the coolant out, even with the Aux heater hoses disconnected.

Thanks.

Just one other thing...........

Anyone know the size of the torx bit needed to undo the engine mount. I left it in place last time, but suspect it would be easier to remove to do water pump.

Thanks
