The starter motor on the Northstar engines is underneath the intake manifold,it sits in the valley just above the crank shaft.

Fairly simple fix. I can do these in about 30 min tops. Need to disconnect the negative battery cable FIRST. Remove the engine cover by removing the 4 13mm nuts. Next remove the front for spark plug wires from the front valve cover and just lay them in the back of the motor out of the way. Make sure you mark the wires before removal so you can install them back in the correct position. Next remove the fuel line quick disconnect lines. (may need fuel line tools for this). Then remove the four 10mm bolts holding the fuel lines to the intake. You will also find a 5th 10mm nut holding the fuel line down back by the EGR valve. Now that the fuel line is loose, you just have to apply slight pressure to the rail to unseat the injector seals from the intake. Next remove the 10mm bolts holding the Intake manifold to the heads. (after this you can simply place a piece of wood under the intake on the passenger side to prop up the intake and access the starter) or you can do it the way I would do in the dealership which is remove the 13mm bolts on the throttle body, the 13mm bolts behind the throttle body to the intake manifold. Completely remove the intake manifold and have clear access to the starter motor. Remove the 10mm nut on the starter for the solenoid wire, remove the 13mm nut on the battery positive cable, remove the two starter bolts and remove the starter. I would also clean the intake ports on the head and clean and replace the intake gaskets prior to reinstalling. I have seen lots of people and I myself am guilty of cheating it at times by just proping the intake manifold up but when in the dealership I like to cross all my T's and dot all my I's.

Rule of thumb is follow the Positive cable from your battery down and it should end up to the starter

Battery , battery cables to starter solenoid and to the under hood power distribution center (fuse box) . Should have a B+ cable from battery to fuse box . Use a DVOM - digital volt ohm meter . Find a wiring diagram for power distribution at http://www.bbbind.com/free_tsb.html also watch videos on basic automotive electrical testing on youtube .

Is 225 an acceptable operating coolant temperature for a 1993 Cadillac Seville STS 4.6L ?


225 F equates to 107.22 Celcius
normal operating range for engines is 85 c(185F) to 98 C (208 F)
100 C is boiling so 212 F is maximum temp anything over is excessive and requires attention

I have a 93 cadillac seville sts,the car will start but let off the gas and it dies, it wont idle, the pedal will even move on its own sometimes, oreilys said the idle air controll, is this right?


The person who gave you this advice are they a trained auto repair tech?? no. Have the dealer test the idle speed control system and see what shows up. DO IT RIGHT AND DON'T LISTEN TO THE MINIMUM WAGE SCREEN READERS AT OREILEY.
