Coolant
 

checked my coolant and the level in the reservoir is between the min and max level. in order to top it up, do i just buy the coolant and pour it in or do i have to blend it with water or anything.
and will i have to check if there is any air in the hoses?

Just poor into the reservoir. As long as engine is cold.

i saw somewhere that coolants are concentrated so it needs water to be diluted or something. is there a certain type of coolant that i should buy.

one thats premixed. i think they are motomaster. in a yellow container. 13.99

I wouldn't worry too much about dilouting it.. you can buy a "premixed" if you're that worried, but by the amount you prob need to pour in I wouldn't be too worried about adding water in also...
you can buy anything really, I normally just buy prestone...

I would not even worry about the over flow bottle, because that's all it is, a over flow bottle, just make sure your rad is full. And if the coolent is between the min and max, you dont need to worry about topping it up.

also i will be cleaning out my IAC valve, any input on what i should use to clean it and what the proper procedure is in cleaning in it.
