NV Coolant Leak After Driving.

Whenever i drive during the day or just a little cooler at night, my FC will leak coolant after i drive it, right underneath the passenger side of the car. When it gets too hot it will leak a good amount of coolant and i would have to fill her up with some water just to get home. Any reason why my fc is getting too hot? My fans blow good. I don't see any sort of leaks when the car is in idle or anything like that, but will get hotter than normal and thats when the coolant will leak. I still need to make the time to check the hoses to see if there leaking anything but so far no signs of anything. Should i upgrade to an oil cooler or change my pressure cap for my radiator? If anyone knows this issue in particular, please help a brotha out ty!

No signs? You said it’s leaking coolant and it’s running hot. Those are pretty significant signs. A bad hose, gasket...something is leaking. It does it while driving probably because as the temperature increases so does pressure and with the leak you probably have air in the system. That can cause your car to run hot.
Replacing the cap is a good idea but unless you’re leaking from the old cap it’s not likely to solve that issue. And neither will adding an oil cooler. I’m not an FC guy but I’m guessing heater hoses are on the lower passenger side of the engine bay. Time to get the car up on stands and investigate. And I think I’d stay with an OEM cap and at the stock pressure rating.

Put it up on ramps and let it run until it starts leaking. Find exactly where the coolant is coming out and you can find what needs to get fixed. Hopefully something easy like a hose or cracked overflow jug.

I would initially suspect bad intake manifold o-rings. You need to use the proper tool to pressurize the system to cap pressure and see where the coolant is leaking.

Overheating can be a result of an air pocket in the cooling system, a faulty cooling system component or bad coolant seals near the exhaust ports. The exhaust will actually heat the coolant due to faulty coolant seals or corroded housings.

Had the same problem with my fd a little while ago. Turned out to just be the ast cap. I'd definitely try replacing your fill cap before anything more expensive
