Here's the thing. Just got my 2003 Pilot EX-L with 238xxx miles for a steal at $700. She's not pretty but runs great. The only problem I'm finding is the coolant is leaking out but I'm not seeing where. I've been reading around the site and see there's an issue with coolant leaking into the ATF. How do I even know if this is a problem? There's no coolant smell, it's not over heating, but I've put in a full bottle of 50/50 mix 2 days in a row and I definitely have not seen that much fluid on the ground. Should I just replace the radiator and change the ATF?
