i have a 94 3.8 and need a heater core replaced is there a short cut on how to do it my self anywere? thanks

 

That job is going to be a total PITA. I wouldnt want to do it myself. But if you want to do it thats fine. Go to your local auto parts store and get a haynes repair manual. It will tell you step by step on how to do the job.
