SOURCE: car won't start

The clicking you are hearing is the starter solenoid. This is a relay that applies 12 volts to the starter motor when you turn the key.

I agree with the parts man, it is probably your starter. Put your car on jack stands, (don't trust the jack itself to support the car with you under it) Disconnect your ground lead on your battery. When you get under the car there will be 2 (sometimes 3) wires attached to the starter. One is a large size wire coming from the starter. It will usually be red. There will be a smaller wire connected to a separate terminal on the startere. disconnect both wires. There will be 2 bolts holding the starter to the engine. Usually 1/2 inch or 9/16 size.. Remove the bottom bolt first. remove the top bolt and as it is about to come out you will have to hold the startere with one hand whilr you remove the 2nd bolt.. THAT'S IT

Take it to the parts store and they can check it for you. BTW, a new solenoid should come already mounter to the new starter.


Hope this helps. Good Luck Loringh

Sounds like the auto shut down relay. Located somewhere in the front grille/bumper area. Relay triggers on impact to shut down all power in order to prevent fires etc. Great idea but can cause exactly the frustration you are having if you don't know it's there!!

SOURCE: My 2001 kia sephia will not hold a charge.

You might have a bigger electrical problem. One of your cables might be grounded this way allowing all flow of electricity to go to the chasis of the car, draining your battery. Check E.C.U. with mechanic

Good luck

SOURCE: 1994 LeBaron battery and alternator good but will not charge

Check for power on the large wire at the alternator. this can be done with the engine off. If there is not battery voltage at that wire at the alternator than there is an open circuit beaten the alternator and the batty. If I remember correctly there are fusible links somewhere in that circuit. Either way you'll have to start digging in to see where the problem is on that wire.

1994 Chevy corsica won't hold a charge changed alternator still won't hold charge


How old is the battery? Did you check wiring circuits for alternator? Do your dash gages show it charging while driving? If it drains over-night with key off, have to check amp draw, everything off.

What is the safe coolant temp in a 1989 Cadillac Eldorado


225-230 deg F is what the Caddy forum says. 250 F can be tolerated briefly when towing, going up a mountain etc.

1991 Isuzu Trooper Leaking Antifreeze I have had


If your leak is at the front of the engine it's probably coming from the water pump. I don't know if there is a freeze plug on that engine. I would tell the repair people to fix your car at no charge or report the to them to the better business bureau.

My 2000dhs is running hot. I replace water pump and thermostat. iI check the oil there is no water in it to indicate a broken head gasket. i was told about some type of heat sensor on side of the...


Yes, this is very common problem of the northstar platform. Head bolts aluminum thread inside the engine block stretching. Although Cadillac improved it in 2000 year model, it persisted on a lot of cars. You will not see any water in oil, at least for the first 5-6 thousand miles, but it will get worse and worse every time, so aventually you will. Engine will "drink" your coolant and no kind of coolant additives will fix that. Especially big coolant loss will be if you floor your gas a lot. On the freeway however you can go for an about 100 miles before engine will consume most of the coolant and overheats. You need to fix the block, cadillac calls the proces "time sert" - they drill bigger holes in the block, thread it and put inside inserts with outer and inner threads, were your original head bolts will go. Dealer going to charge you $5500 for that, and most mecanics will charge around $3200. That is why so many people selling their caddys cheap on ebay saying that there is a coolant leak somewere. I bought two caddys like that. Now I can fix that kind of problem easy. I bought all of those expensive tools for time serting. And by the way, something I learn the hard way, even if you are mecanic but never ever rebuilded northstar before expect lots of problems and difficulties. Very complicated hi tech engine with balanser shauft. Parts are expensive too, upper set of guskets will cost you about $320 and if you buy all the lower seals too than $500. Piston rings $220 and good luck finding it in autozone. I guess it is time for you to find out how are those used car dealer shues fit you :-)

Alternator


J,
I have a 99 and aftter posting the same question was given some bad info, at a different sight. On the 99 I found it necessary to remove the fan assemblies, drain the radiator and remove , you have to move the condensor for the A/C but it does not have to be removed. I also had to remove the upper plastic piece in the engine compartment and the lower gravel shield. After this is done you will have a clear view of the Alt., mine was the watercooled version, I also replaced all the hoses and belts while I was in there. You may want to have the Alt tested before removal this was a 2 day job in the driveway for me. Mine is also the northstar version , I believe the 2000 is the same.
