Damnit, i forgot to ask:
When i change the oil. is 10W40 good for this engine? Buddy said it doesnt really matter with those old engines because there is so much space for lubrication everywhere, but i want to make sure.

Also. I'm going to change the cooling liquid and thermostat, because i dont have a working thermometer in the car so i dont know how hot the engine gets.. How many liters of water should i put in the radiator?
