it only make sense to do both at the same time since they are right next to each other.
the hoses are disconnected, and the coolant is drained.
i also took the opportunity to replace all water hoses when i did the job.

Parts were $372.75 from our forum sponsor. I bought the kit at the top of the page which includes the water pump, gasket, and low temp thermostat. You'll also need 2-3 gallons of coolant ($35 per gal from Porsche) and a bit of gasket sealant.

The DIY instructions are here. Looks like about a half day job max. My local indy wanted $550 in labor. Over $500 in savings is enough to get my fat lazy butt off the couch. Your motivations may vary.
