I have a 1995 with 157K miles on her. I knew the KDP might be a problem but I thought it was a hard job to tear the front of my truck apart and check it. I have been leaking a ton of oil so I pointed my flashlight on the front cover right under the idler pulley bracket and stepped up the idle... ... . a real nice flow of oil was running out. MY Message is that it took me very little time and effort to get to the KDP unfortunately in my case it had already cracked the housing BUT I was lucky it did no other damage. If you are wondering if your KDP is going to get you take about 2 hours and check it! You dont need to pull your bumper,innercooler or transmission cooler. I pulled six bolts out of the upper core support. 2 bolts holding the hood release. slid the overflow bottle off as well as the windshield washer resovour. took off radiator hoses and the radiator simply slips upward out of the truck. Took the pulley off the idler bearing, unbolted the idler bracket. I used an air chizel to losen the fan clutch. took the harmonic balancer off with a 1/2" impact. took all the tin cover bolts off and pulled the front tin cover. SIMPLE SIMPLE SIMPLE. DO IT Today before you ruin your motor :O)
