Last week I drove about 120 miles and my first re-start after getting
there was so sluggish it almost stopped while cranking but I guess a
cylinder just happened to fire at the right moment and it started. I
curtailed my visit and the few errands I did I left the engine idling the
whole time. As soon as I got close to home I left it with a mechanic.
Naturally the next day he called to say they could find nothing
wrong...it was starting vigorously. Charging system checked out and as I
said previously the battery is new. I suggested maybe it was temp
related so they let it get warmed up and still nothing.
He said putting in a new starter is about $270 all told and that's too
much to do on speculation alone. I agree. When I picked up the car it
was still starting vigorously and did so for about a day and then the
sluggishness returned.
I am starting to notice a correlation between heat and this problem. I'm
guessing the starter gets less functional as it gets hot although I
suppose it could also be something in the engine making it hard to crank
at high temperatures.
Yesterday after some long driving with progressively worse starts as the
day went on it finally culminated (luckily within walking distance from
home although it didn't prove to be necessary) in it not being able to
crank at all. Being at a fast food place I placed an ice cube on the
starter. Also spritzed it with water. Got back in the car and while it
was still just barely there it did start up.
What failure mode is happening inside the starter (if that's what it is)
that causes it to get weaker as it gets hotter?
It's still not a sure thing but while I might not want to spend $270 on
spec I am willing to buy a rebuilt starter for about $75 and put it in
myself on hope alone.
Anything I should know about starter R&R on 1995 Jeep Grand Cherokee
Limited inline 6? I've never done one but everything I've read makes it
sound pretty simple. Disconnect the battery, disconnect wires from the
starter, unbolt it and bolt in the new one, etc.
