I have a 97 saturn sl2. when i first start the car in the morning it starts fine but when i run it and drive for a good 10-20 minutes and turn off the car i try to start it again it wont start just starts clicking from the starter. But if i wait a good couple of hoing else ?urs(cooled down) it will start again with no problems. but again if i drive it again like before it does the same thing. is it the starter or something else ? I have had the alternater and battery checked and both are fine
That condition in the Auto Electric Industry is referred to as "Hot Soak", meaning when the starter absorbes heat, the heat "soaks in", the result is excess resistance which the solenoid cannot over come to start the car, as it's cools off, the resistance lessens and viola, the car starts. To verify, get a small spray bottle of water, carry it in the car, when it gets hot and won't turn over, open the hood and give that solenoid on the starter a couple of squirts, it will cool that solenoid fast and if the car starts, you've isloated the problem to the solenoid. Your car was produced in 1997 with 2 different starters, an early model and a later model however both have the same solenoid, if you can find just that part and change it yourself do so however, you'd be doing a lot of work to install a new part on an old starter, better, in my opinion, to replace the whole starter, that way you know the whole thing is up to par
a few things on top of daniels post..that along with most other new cars use load dropping relays to power the starter solenoid... this reduced the load through the ignition switch... its usually under the hood in the relay center... you may have a label to identify it.. or you will have to use the owners manual to identify it... it will make a clicking noise.. as will the starter solenoid..this is the starter relay.. there are others like it..you can.. if you buy a new starter relay. and plug it in sometimes solve the no crank condition.. it has worked many times...do not throw away the old relay.. carefully examine it.. you can drop it back into the relay location with the cover off. and manually squeeze the contacts.. this should send power to the starter solenoid.. and allow you to manually crank the engine while the car is hot.. if it still does not start when you manually squeeze the contacts.. and you have cleaned the relay contacts.. you probably have a starter going bad.. that car is coming up on 15 years old.. so it could use a starter soon.. this is the starter motor ... the rear view... the upper part is the solenoid... the lower part is the actual motor..there is also a serious problem with dirty battery terminals.. dirty ground connections.. dirty or loose battery cables at the starter and OR at the relay center... i have had to clean the battery connection to the relay box a bunch of times over the last few years..
Well guy,your question got you a great and free education, who ever supplied this relay info did a nice job, it took some time and effort, he knows what he's talking about.
nice wynep you have nice sound for ans i like it
