One guy got charged $900 from dealer for oem radiator (plastic / aluminum).
Some shops charge $500 or somthing which is really expensive.

Here is what i recommend doing, go to http://www.radiatorbarn.com/ , buy the all heavy duty all metal radiator $125 shipped. go to autozone, buy new upper/lower radiator hoses ($35), New thermostat $10. collent $20.

Do it yourself, it should take 3-4 hours depending. It's really simple. Here's a DIY
