Driver's side is a 17mm Alan (front of block near alt) ,Passenger side is a 5/16 Alan ( Behind starter)




Auto zone has a three piece alan set for the 17mm its around 10.00. I already had the 5/16 from sears, is around 5.50

I only pull them when i cam swaping heads.

The driver's side i can get too with the header loose, not sure if you can get to it with out having to pull the altinator or not.

THe passenger side loosen the long starter bolt and remove the short start bolt, it will slide out of the way to get a 5/16 alan and a 12" extension to get it out. You dont have to pull the starter.


Good luck.


For what it is worth, you could take your car to a quick oil change place and they can flush the coolant by only using the radiator fill . Granted it costs more but its less work.
