Reviews of Bosch starter motor

All of a sudden one day I started up my car just like normal, let the glowplugs heat then bump the key just long enough to get it started, but this time and every time after, the starter grinds right as the engine fires and as it disengages the starter makes a grinding sound just like i've held the key too long even though I havent. I took the (2 month old rebuilt bosch) starter off and checked everything and its all clean, I greased everything and re assembled. Still the same. The problem is still present on the old starter, we suspected it to be the sprag clutch at napa.

Always try to get quality brands like Bosch. They always seem to last forever and they replace anything that is worn internally too so you can almost guarantee it will last.

New starter (Bosch) (Late 2017)

It killed what is left of my soul but I mickey moused it. All the starters that match at the parts stores (bosch, ac delco etc) lack the correct plug. Used a couple ugly .250" flat connectors. how embarassing.

some starters may have a resistor bypass connection.. that when the solenoid plunger is pulled in.. the R terminal is connected to cranking battery power.. this wire is hooked to the coil positive.. where the other wire to the coil positive comes thru a resistor.. this allows the coil to get higher voltage while cranking.

i also noticed that the starter is the original bosch and the positive power lead going to it has some of the insulation cut off right where the wire bends to screw to the starter.

So, after a fun summer and fall of some great worry free driving something came up.... it wouldn't start properly. So naturally I took the battery to advanced auto parts to test it, it worked fine and passed, then tested the starter, and was reading a bit slow, can't quite remember the cranking speed but it was in the low 100's RPM. So after days of having to pop start the car, yes I know.... poor clutch! I got a brand new REMAN Bosch starter, and installed it. For the next two days it started just fine

I've already replaced the starter 2 time in the last 3 years, with a rebuilt Bosch starter. I don't think a rebuilt starter should go bad this fast. I put about 15,000 miles a year on the car. Even a chepo starter from the local parts store should last longer than that. So I'm done with Bosch.

In the process of rebuilding my starter too since the Bosch Reman I bought crapped out on me.

The starter is a Bosch premium re-manufactured unit and tested good before I put it in.
