| Message: | My first guess is alternator. Your voltage should not drop near that low on cranking Could be the voltage regulator in the alternator. A bad alternator will take out a battery long before it is even middle aged. As I recall you have a 97 or 98. I would expect the alternator to be failing at this age. Remember, only a Denso made specifically for this car will work. The sound you describe is highly unlikely chain slap. You'd have had to have lost your tensioner slippers and nobody has reported premature failure on 3rd gen tensioners that I am aware of. How did the guides look when you tore it down? My car had the secondaries replaced and about 6 months ago I noticed the same sound you described. I still get it, sounds like a chain rattle and it lasts for 2-3 seconds. Most likely, I have decided, it is the belt tensioner pulley or idler arm. These go bad on a regular basis from what I know. As for temp, it is a icy cold 65 in the AM and my car makes more noise on startup than it did during the summer. It only last a a few seconds. I am sure it is just a stiff S belt and rusty bearings in the idler pulleys. It's next on my fix list. | ||||
