I have 200k miles on my 97 Diamante. Still looks and runs great.
Your knock sensor is located under the hood, center, front engine area, below intake manifold, mounted on block.
Changing the serpentine belt on a 97 Mitsubishi Diamante is a fairly easy task. All you need to do is get a wrench and loosen the tension pulley and pull of the serpentine belt.
The 1997 Mitsubishi Diamante OBD 2 port is under driver side dash next to center console
The engine computer is also the regulator.
The powertrain control module is visible from the engine compartment. It is in the firewall on the passenger side. The RAP module for your keyless entry/keypad is in the jack storage compartment.
YES, if you know what you are doing. You will need the complete engine and transmission wiring harness and computer plus the fuel pump for the 5.3L engine. The wiring harness and computer on the 97 will NOT work.
First of all, your smog laws, if any, would not allow this. If you have none, then yes, it will bolt right in. But, I would not do it, because, the 88 has about 100 less hp. NEW ANSWER: Yes that engine will bolt right in. But the problem is that it will never run. You would have to get a 88 computer / ENGINE CONTROL MODULE and the wireing harness for the 88 engine,computer,transmission and fuel pump. You would also have to change the transmission because the 88 computer will not shift the 97 4L60E transmission. You will also have to change the FUEL PUMP. The 88 requires 9 to 13 LBS of fuel pressure and the 97 Must have 60 to 66 LBS to run the 97 vortec engine. This means you will have to spend alot of MONEY to make the 88 engine run. Your best bet would be to put a VORTEC ENGINE BACK IN IT and be done with it.
