I need to remove my starter on my 98 Diamante but I can not see all mounting bolts and I need to know where the bolts are located.

Your 1999 Mitsubishi Diamante is a 3.5L MFI SOHC 6cyl engine.
MFI = multi-port fuel injection
SOHC = single overhead camshaft
This answer covers Mitsubishi Diamante1.8L, 2.4L, 3.0L (SOHC and DOHC), 3.5L, and 1997-2000 1.5L Engines.

2.4L engine shown, others similar.

Fig.1 - CKP position and its two mounting bolts


In Fig. 1, the two arrows point to the CKP (crankshaft position sensor) mounting bolts to remove. 2.4L engine shown.

Fig.2 - CKP reluctor removal

Remove the sensor and slide the reluctor wheel off of the crankshaft-2.4L engine shown.

1. Disconnect the negative battery cable.
2. Remove the timing belt.
3. Unplug the sensor connector.
4. Unfasten the two retaining bolts, then remove the CKP sensor from the vehicle.
5. Installation is the reverse of the removal procedure.

I had a Toyota with an odd-ball starter bolt from the back side of where the starter mounted. It didn't even look like a starter bolt, but sure enough, it was. So keep checking, you may have a third bolt you haven't found.

REMOVAL & INSTALLATION

It's located near the cam gear on the front of the engine however, the crank sensor, to the right of the oil filter near the bell housing is the part notorious for going out on these cars, and causing a p0322 and/or p0341 code, and sometimes others as well To replace the crank sensor you have to: Support the motor with a floor jack. Remove the starter, 2 of the starter bolts connect to the motor mount. Remove the motor mount from the frame, very easy. Remove the oil filter. That will give you just enough room to get an allen wrench in to remove the bolt holding the sensor in.

Hello and thank your for choosing fixya.com The other bolt is probably on the top; you may need to take and extension and socket and slide it above the start if possible and try to locate the bolt. If that doesn't work, you may need to get a service/repair manual to locate it. I recommend a CHILTONS as it is more descriptive in directions. Please let me know if you need any further assistance, have any questions or comments, and I thank you again for choosing fixya.com to help you with this matter.

Get a chilton manual online if you a DIYer and it will save you time and money..Basic step by step-Remove postive batt cable. locate starter, obtain new starter to see location of mounting bolts,remove starter mounting bolts,remove wires firrst if accessable if not starter will lower when mount bolts out ,then remove wires noting where they go. hookup wires and replace in reverse. note:some can be hard to get to-always handy to refer to a manual Good luck..oh replace positive cable when aal is tight and right...

1. open hood
2. remove batt. cables
3.remove batt. cable on starter
starter is located lower pass. side of motor
(also might be a couple of other wires connected to the starter remove them as well & remember their locations).
4. remove two bolts that mount the starter to the trans. bell housing. and remove starter
5. install new starter and hook wires up with the batt. last.
