Remove both wiper arms and all 4 pieces of the plastic cowl at the base of the windshield (2 upper, 2 lower). This gives you tons of room back there.I will be replacing my oil pan gasket and I plotted out my course and it appears these bolts will be my problem. At first glance it seems like one of the bolts is even hard to see. This is on a 98 DOHC. Any suggestions? Is there enough room to use heat?
