1991 mazda 1600 eunos mx5.Does it have chain or bet cam drive?Ple

That is a tricky question! Some engines use BOTH ENDS of camshafts for certain things! Are the lifters above the valves? If so, and you pick up the cam(s), the valve lifters could (1) fall out, or (2) fall apart! You DON'T want to mix parts up like that! But what you CAN do, is loosen the cams, then put a piece of black plastic electrical tape around each valve lifter, so they cannot fall out, nor fall apart when you lift a cam out!

Remove every thing off the front of the engine and valve cover. Remove the belt/chain tensioner. Remove the belt /chain. Remove the caps for the cam shaft.

Your radiator is leaking internally, leaking transmission fluid from the transmission fluid cooler into the radiator where the coolant is. You can't fix it, just get the radiator replaced and then flush the coolant.

Check and tighten as needed.
