SOURCE: 2003 mitsubishi diamante thermostat

You're going to lose some coolant, so have a bucket or other container ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing which is bolted to the engine. Remove the bolts (not the hose) and lift the housing to expose the thermostat (may require a little prying with a screwdriver or similar tool). Note how the old thermostat is fitted (which end is up), lift it out of the engine, and then remove all traces of gasket from the housing and the engine. Install the new thermostat and gasket, replace the bolts, add coolant as necessary, and you're done.

SOURCE: 2000 mitsubishi diamante has spark

At injector's, need to check if you have ground pulsation, to check, connect test light on pos (+) battery terminal, now your set to check ground, at injector harness, probe wire's, while some one cranks engine, look for pulsation, if you don't have pulsation, it will need a computer, injector pulsation is control by the computer, if no pulsation, then no fuel can get into cylinder.

I have a 2003 Mitsubishi Diamante. It seems that when I am driving at higher speeds the engine runs a little warm. I am not overhearting but want to address issue before a problem. What could be causing...


There are several things to check:
  • Low coolant level
  • Leaking radiator hose; a small leak under pressure would cause you to lose coolant
  • Leaking radiator line (located on the bottom of the radiator
  • Bad thermostat; A bad thermostat will not allow sufficient coolant to flow to keep the engine cool

How do you replace spark plugs in a 2003 diamante?


You have to remove the plenum, air intake, air filter, throttle body, injector wiring bar, all wires from the left side of the plenum. It will take about 2-4 hrs depending on your handiness.
