I have a 2003 Mitsubishi

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 i make the

Their is a fault with the electronics on one of the vehicles electrical circuits, or one of the sensors is activated and reading a mechanical fault. This will bring up the malfunction indicator light, you will need to see a dealer with an electronics reader to find out what this fault code is meaning. Some dealers will read it for free, and then charge for the repair from that point. If it was a false code they will also reset it for free, althogh i have heard some dealers can charge up to $100. OR you can even hire a fault code reader from an automotive parts store and read it yourself. If it is an orange light, just get it to a dealer when you are able to. If it is a red light, avoid driving it and get to a dealer ASAP. this will prevent any further possible electrical damage and any other mechanical damage from what ever the fault maybe. Also, their is a safety issue if the fault is relating to a safety feature of the car. It is hard to pin point an exact fault and exact cost. Cost will vary with the type of fault. Once repaired, the dealer will be able to reset the light for you. Goodluck

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.

Have a 2003 mitsubishi galant

Blowing fuses are very difficult to find out why. The transmission is stuck in third gear because it is in limp mode because the speed sensors are not working. I believe that you will find that the input or output speed sensors are where your problem is. Does the car blow the fuse every time you turn the key on? Or is it every once in a while?

My car shakes when i hit the brakes

You need to first isolate the breaking problem between the front and the rear . Here's how to do it: While driving about 30mph on a straight road , put the transmission into neutral . Then , while holding the emergency brake lever in the release position , gently apply pressure to the emergency brake . Do you feel the vibration ? If yes , then you probably have out of round drums or desks on the rear axles . If you don't feel any vibration while using the emergency brake , then your problem is the front rotors . They are probably not true . Or they could have hot spots which are little bumps on the rotor surface. Have them turned on a brake lathe to correct the problem . I'm assuming you don't have a bent rim or bad wheel bearings . I hope you have already checked these things before posting your question . If not , do that first .

Auto trans... when first starting engine in

not completely sure it has something to do with the auto trans, but more likely the hydraulic lifters. the older cars used to have a fixed valve clearance with tappets, but now they use hydraulic lifters. the problem with these is if you don't change the oil at a regular interval or do alot of stop-start driving, the oil becomes sludgy and does not flow into the small tolerance holes in the lifters. the beautiful thing about oil is that it thins out as it gets hotter to a point, so as the engine warms up, the oil thins out and flows into the lifter hydraulically pumping them up and closing the gap, i would suggest to change the engine oil to manufacturer's specs and add a "lifter free" product, after a few weeks it will reduce dramatically
