Maltese RX7

I am loosing a coolant whenever I use my RX7. Not a lot.
Must be some seal somewhere which went bad. Where can I look?

Which tap do you prefer to use for checking/ filling. White tank, middle filler cap or near intercooler?

Check your coolant lines to make sure it's not leaking, also check your ast (if stock one) to see if it's leaking around the hose or where the top part of the ast is connecting to the bottom part. Also check your water pump, below your alternator. Sometimes the water pump will not leak at idle, it'll only leak if you rev your car high or drive it mid to high, just park your car and peek under the car to see if it's leaking. Also check your upper coolant hose to see if that's leaking. Unfortunately all 3 of these happend to me!

... and don't forget to check your radiator where the plastic end tanks meet the aluminum core. That seems to be a pretty typical place of failure. If you don't know how to do that, reply to this post and I'll take the time to type it.

Oh, and you should be checking coolant level at the filler neck when the car is cold as well as the overflow tank.... But if you're worried about a leak, all kinds of funny things can happen in the overflow tank, so it's generally best to check the filler neck.

Also just change your radiator cap. I had coolant losses for a while and ended up replacing mine twice in the same month. I replaced an old bad one with a new bad one and then a new good one. That was a few months back and I haven't had any problems since.
