My car is starting to overheat. Im not to mechanically implied so if you guys could help me out it would be greatly appreciated. Where should i start and how much does it cost?

 

You can start by checking your coolant level. You can also start by replacing the hosing that goes from your filler neck to overflow bottle, and buy yourself a mazda OEM pressure cap from the dealer.
Also there should be a black shroud that covers the bottom of the engine, its made of plastic and it helps with air circulation to the radiator.

Finally, try searching.

 

Here's what I check for coolant problems:

Leaks (duh)
Air pockets
Faulty cap
plugged radiator
faulty clutch fan
bad ducting
bad thermostat
