Have an '83 12A FB Rx7, I wasn't able to find any good posts in here for the most common coolant leaks so I wanted to see if anyone could help me out with finding all of the places to check for Coolant Leaks.

My engine has had a consistent coolant leak for the longest time, I just got into working on my Rx7 again and after rebuilding and modding the Nikki I think it's about time to find where the steam is billowing out from my engine bay. (I've been topping off with water, no coolant)

Besides just inspecting for drips, I'm just planning on using UV Dye packs to find the leak. And, if worst case I can't find it, I'm considering using K-Seal as a last resort.

Just looking for some advice from you experienced folk!

Thanks!

 

these are old cars, basically it can leak from anywhere at this point.

the only real odd place is that the intake manifold has a coolant passage, and its sealed by two o rings, and these go bad eventually.

other than that its just the typical water pump, hoses, radiator
