The heat shield fits over the exhaust manifold, and it also provides a source of heat for the air intake when cold to help vaporize the fuel mix faster and burn completely. The igniter for the coil is part of the ignition system; it is a more modern way of using points in the distributor. Nippon Denso was an OEM company for Toyota.Thank you. So are you saying mine is missing a heat shield? Is it supposed to have a hot air intake? Nippon Denso coil? Wht's that all about. Thanks for your help
My truck came with an alternator like the spray painted one in the for-sale truck above. Notice how the bracket is maxed out, and the bracket is leaning on the alternator itself. A previous owner of my rig took the bracket to the grinder instead of finding the proper alternator or belt, just to get barely enough tension to make it work.
