Could be the water pump or a dozen other root causes. Did you have the entire cooling system pressure checked or just the radiator?

Assume you are still leaking coolant onto the driveway?

Go rent a cooling system pressure test kit at the local parts store. Obviously you are still losing coolant so get the pressure tester, pump up the system then look for leaks. There is a dye you can add to the coolant to aid finding the leak(s) with a UV light. I rarely use that. It's usually pretty obvious once you pressurize the system.

If there are no obvious external leaks then it could be a head gasket, cracked head, block, etc. No sense getting alarmed, diagnose the problem.

No leaking anywhere.

i brought it to my mechanic. He thinks it may be
a couple hoses.

when driving it's sluggish and stalls. Especially when I take slow turns or sluggish at 30mph.

i hope it's not a cracked head

I'll let you know either way

Well if you are still looking for things, you can check a cracked head/head-gasket by renting a block tester (or buying) from your local auto parts store.

Basically it's a large tube/funnel/baster that you stick on the top of the radiator (where the cap goes after taking off the cap). You fill the tube with the block tester liquid (purple) to the designated line on the tube. You'll start the engine and let it idle and warm up. While doing this, you squish on the bulb on top of the tube to suck air up through the funnel. (It's got piece that lets air come through, but the fluid stay in).

If you have a cracked head/bad head-gasket and are using coolant, then there is a very very good chance that exhaust gasses will be making their way into your coolant system. If exhaust gasses are in your coolant system, while squeezing the bulb on the block tester, the coolant will slowly (or quickly depending on how bad) turn from purple to yellow. If the fluid doesn't change color at all, then you're probably good to rule out a cracked head or bad head-gasket.

Renting the block tester is only about 20 bucks.
