James's 99 Miata

Before Le Hardcore Racer bros come in and tell you aluminum or bust, unless you plan to track it, you can just replace it was an OEM radiator and be okay. When you replace the timing belt, do the cam seals, tensioner pulleys, CAS O-ring (since you'll have the valve cover off) and I believe the front crankshaft seal (?) may be suggested.

Before all of this, make sure BOTH of your fans are kicking in. The one on the right is the regular cooling fan and the one of the left is the a/c fan (if yours is the same as mine). If one or both isn't kicking in, you'll get the temp spikes.
