Nissan: Overheating 94 Nissan Sentra

My personal list of things to check in the event of overheating based on
cost and effort:

1. Radiator Cap (really, this is often a cause)
2. Purge coolant system (evacuate all air bubbles in system)
3. Hoses (minute cracks can cause loss of coolant and then overheating)
4. Thermostat (this can be checked with a thermometer and pot of warming
water)
5. Raidator (if you can see build-up floading in your radiator, that's not a
good sign)
6. Water pump (usually sounds bad when failing)

Good luck.

overheating despite changing the radiator and the thermostat. What else do I
need to look at ? 

I'll add a bit to #6 (water pump):

Make sure the antifreeze looks like it's circulating properly with the
radiator cap off. If it doesn't, pull that water pump off and check
the impeller. I had one a few years ago on a new (to us) customers
vehicle that had the impeller corroded off! There were only about 3
little severely corroded `fingers' where the impeller should have
been. A new pump and flush later all was well (amazingly the hoses
and thermostat had been replaced at another facility). I guess that's
why we charged a little more at our shop, we actually checked the end
result of our work. LOL

If every thing checks out to be good, I have seen headgaskets leak and heads
crack on the sentra 1.6l.
