    Low Vacuum Pressure Switch

    I paid $120ish in 2017, but I got it the next day. And I got a free replacement twice for $0, so far. Saved a good $300+tax because it was $150 by the time I had to warranty it, twice in a short amount of time. The second replacement has been good for over a year, so far. Being able to make a...

    O'Reilly's is lifetime warranty. I'm on my third since I bought one in 2017.

    Hot hot should my e4od run?

    The C6 in the RV ran 180-210 in the pan, with a deep aluminum pan and a big cooler.

    Low Vacuum Pressure Switch

    The brake light would randomly go on and off in the 87 F250, but that was likely the speed sensor in the diff or whatever.

    Low Vacuum Pressure Switch

    First time, i wasn't towing. I was braking on a probably 1/3 mile long right turn lane, coming into the NE corner of Amarillo TX. The divided highway I was turning onto, I knew lead straight to a big TA truck stop, but with a few red lights by i40. flashers on, going 40mph in a 65, stomping the...

    Low Vacuum Pressure Switch

    BRAKE light I lost power brakes three times on the 27ft RV. First time in 2019, the alternative belt was lost and I didn't know. Second time, in late 2022, a nearly new vacuum pump stopped working entirely. Third time, in early 2023, a nearly new vacuum (that replaced the one from late '22)...

    Low Vacuum Pressure Switch

    It hasn't worked in any of the three IDIs I've had, 85, 87, 89. Get a cheap Chinese vacuum gauge. A couple of examples. Analog: https://a.co/d/cwGMiUZ Digital: https://a.co/d/9P8Sqjd I have the digital one I have yet to install.

    My '89 is dead, what's happened?

    A universal one is $10-30 ;) just avoid Dorman/Napa one. The one I got in an emergency for my bug has a weak return spring so it likes to leave the starter spinning when I let go of the key. I got a Standard (SMP) one from O'Reilly that's definitely differently made, it has a single sided key...

    V-belt tension

    Wedged next to the alternator and pulled with one hand, then tighten the upper bolt to secure the alternator. Then tighten the pivot bolt. Just don't go crazy with it is all. It's pretty much the only good way to tension that belt on Econolines like I've had for 5 years. I recently had a...

    V-belt tension

    I use an old one of these to tension the alternator belt. https://www.harborfreight.com/24-inch-general-purpose-tire-iron-93230.html

    EGT questions

    How new are you talking? Cars from 20 years ago were in a transitional period. Some still had cable driven throttles but a few years later, on the same models, that was done away with for computer controlled throttle.

    That's why I've never tried to buy a Smart car. They require special Mercedes tools.

    EGT questions

    People have extreme phobias about older vehicle breaking down, I suppose mainly because they don't know how to fix things and the fear of the unknown is a powerful thing. And if they have kids, the fear can be even worse. They seem to think it's going to be breaking down every few weeks, and...

    My '89 is dead, what's happened?

    And the starter on my f250 mysteriously physically broke once. i just drove it across town, parked it, and then it was broken. had to be towed to a shop. one of the wire connections broke or something. very weird

    3G alternator upgrade

    Yep. I even had to do that on the 1g alternator that i got from O'Reilly for the 87 F250, because it came a serpentine pulley and the truck was V.

    3G alternator upgrade

    Yes, but if it goes bad, I'd have to know what to tell the store I want

    3G alternator upgrade

    I suppose it's very useful for setups with winches etc where you need power when idling. Or perhaps very short stop and go drives. I didn't have an issue really with old 1Gs on the F250 or RV. I did replace the alternator on the f250 later the same year i bought it, but that could happen to a...

    3G alternator upgrade

    You do need the harnesses that plugs into a 3g alternator

    My '89 is dead, what's happened?

    If the rod thing is broken, the ignition switch will feel floppy/loose in rotation. It could also be your starter relay/solenoid. If it's automatic transmission, it could be the neutral safety switch. Put in neutral instead of park and try.

    12V power for accessories

    Yes [battery]-[relay/solenoid]-[fuse panel]-[accessories] And the relay/solenoid activated from radio switched power source. Although you might do this for extra safety: [battery]-[large fuse or 12v auto reset breaker]-[relay/solenoid]-[fuse panel]-[accessories] That way you have some...

    3G alternator upgrade

    You might try loosening the curved bar that the alternator tightens to and rotate it more to the passenger side. I'm running stock length belts with 3g on my 89 E350 and it's nowhere near the end of the curved bar. edit: oh it looks like you did. Well i checked mine just now and it's similar to...

    12V power for accessories

    Yeah, that's just the first example I saw.

    EGT questions

    That's the brand the RV had from way back around 1985-87 with the 085 kit, and it still worked. As opposed to the Banks branded one that was put on (presumably) around 1989 on this van, that went bad. I have an Autometer one on it currently.

    12V power for accessories

    Yes. That type of solenoid is typically used as a battery isolator, such as on old RVs, but your intended use works too. Put a fuse panel for the accessories fed off of the solenoid. And if you want to be extra safe, a fuse between the battery and the solenoid. The easiest and safest wire to...
