Cooling problems

[ecp]

Last Monday I took my boxster up to some mountains and was having a great time, until it broke down. It turned out to be the harness on one of the coil packs had come loose. Long story short I started driving home, and was sitting in traffic and after I started moving again I got a low coolant light, I pulled over and shut the car down and coolant had started running out of the overflow. I let it cool down a bit and started driving again, and probably only made it about 5 minutes until the temp gauge started creeping up. It ran up to probably around 210 and I shut it down before it pinged all the way up. It didn’t run poorly but it didn’t seem happy. I called a tow and waited, I cranked the heat to try and cool it down but the air was cold.

When I broke down the first time I noticed a little coolant residue around the expansion tank cap. I noticed some leaking from the expansion tank as well and have stripped out the trunk carpet.

So far I have been able to confirm the expansion tank was leaking, and the water pump had some play in it. Could the tank just have cracked from all the pressure?
I’m replacing the tank, water pump, thermostat, and the heater core (smells like coolant when I would turn the heat on in winter occasionally). The car starts right up and seems to run and idle fine, no exhaust smells or intermix or smoke. Is there anything else I should worry about, or has anyone else had a similar experience? I feel like it will be fixed once I get the new tank in and bleed the system, but I always worry about a worse case scenario. It’s a 2003 s with 133k.
