Guest Magoo Posted December 13, 2014 Share Posted December 13, 2014 (edited) I spent my early days working on these systems. They're like most anything else -- once you understand what all the components are and their intended functions, the hose routings and so forth are self-explanatory.EDIT: After a moment I realize the above must sound very smug. I was fortunate to work in the factory-supported environment with all the OE training and manuals at my disposal. But at the time, I remember thinking how difficult things must have been for the guys out in the aftermarket and third-party world, working with only a Chilton manual and the vacuum schematic decal on the core support. That would be a relative nightmare. Edited December 13, 2014 by Magoo (see edit history) Link to comment Share on other sites More sharing options...
joe_padavano Posted December 13, 2014 Share Posted December 13, 2014 EDIT: After a moment I realize the above must sound very smug. Not at all. I completely agree with you. If one actually takes the time to read and understand the factory service manual, the routing and function can be understood quite easily. Unfortunately, most people simply open the hood, throw up their hands, and run screaming. Link to comment Share on other sites More sharing options...
Mssr. Bwatoe Posted December 15, 2014 Share Posted December 15, 2014 No joys, these were the dark days of automobiles, Ford with its EECIII system, Gm with feed back carbs and semi computerized controls, mc solonoids and electronic advances...Hondas with more hoses that a player piano...And they didnt work very welleven with breakout boxes and ohm meters...as much fun as the flu!

Steve_Mack_CT Posted December 15, 2014 Share Posted December 15, 2014 Aahh, our 1989 Mercedes Benz 560 SL is squarely from that era. While all is well under the hood, I am contemplating two "voluntary" jobs as relates to the vacuum hoses on this car:1) Begin replacing these hoses as a preventive maintenance step. They look decent but I also know the many ways leaks can occur and deterioration can hide. Easy enough to monitor with the handy "economy meter" in the dash that is really a vacuum gauge.2) The Central locking system on this car is vacuum operated and one of the only, if the only thing I am aware of that is not functioning on this car. For that reason I kind of want to fix it, but part of me also does not see the need, since the top is down on it 95% of the time when it is in use.Hmm, I figure job #1 has a 50/50 chance of being implemented next year, especially if I get bored/am out of things to do on this one, job #2 though, may wait a little longer...
