#41 of 82 '95 Diamante 3.0 SOHC won't start by jbnc1 Jul 04, 2007 (2:04 pm)
I bought my D in Oct. of '05, since then i've been replacing original parts about every 90 days. Last week it started running hot til one morning I was driving it on the hwy when it shut off when I took my foot off the accelerator. I have now learned that the intake gaskets were melted down to the metal allowing the fluids from the radiator to drain into the exhaust. I've had the gaskets changed, heads and valves checked, replaced the timing belt and etc., new spark plugs and wires, and new fuel filter. When I attempt to start it, it is still spitting fluids from the tail pipe. what else must be done to start her up?
#42 of 82 2000 Mitsubishi Diamante by jbooth5 Jul 10, 2007 (2:08 pm)
I have a problem with this annoying clicking sound when I start my Diamante. It only last for about 20 seconds, and it goes away. If I turn the temperature dial above 70 degrees, the clicking sound stops. If I turn the temperture below 70 degrees, the sound starts clicking. Does anyone have any ideas of what my problem might be? Replies to this message: diamoney (Jul 12, 2007 2:58 pm) doiturself (Oct 03, 2009 12:29 pm)

Replying to: jbooth5 (Jul 10, 2007 2:08 pm) j, If you have automatic climate control, more than likly your bearings are going out on your blower-fan. I have had the same deal happen in other vehicles where the fan would not come on until you tapped the motor on the fan. You can deal with the 'chirping' or replace the fan or fan motor.

#45 of 82 2002 DIAMANTE - Having Alternator/Battery issues by mdfall Aug 12, 2007 (3:08 pm)
Hello all I have problems with my alternator. It is over charging the battery (which gets hot to a boiling point). My friend who is mechanic helped me replace the Alternator and the battery. I have both of them new. Now despite the new parts, the issue keeps coming back. I had to replace a second time the alternator and the shop agreed to give a new battery too. Today the mechanic told me that he needs to replace the Battery Relay (located in the fuse box).   On top of that, when I drive the car on the highway (60 mph), the car over heats. When it is stopped and on idle it looks normal. Are the issues related? Please help me come up with a solution. Thanks.

Replying to: diamoney (Jun 01, 2007 11:33 am) I have a 1997 Diamante with same issue (100k miles). Mine was carbon in the engine which I removed with SeaFoam which you can buy at Autozone for about $7. I sucked the SeaFoam up through the PCV Valve (pour in bowl and do this slowly, so engine wont die) while I jockeyed the throttle cable under hood (to keep engine from dying) to get all of it sucked up into engine intake. After all is sucked up, turn off car for 5-10 minutes and restart. It will smoke out the tailpiple like crazy for 10 mins (your neighboors might call fire dept from all the smoke!), but should smooth your idle if carbon related. My idle was smooth as glass not right after this cleaning, but after several days of driving. Seafoam is oxygen and catalytic conventer safe and will actually clean the converter, too. Your plugs should be of the 100K mile variety, but if cheap gas, carbon may be your issue. You may have also have EGR issues and check that valve and/or blockages, too. Decarboning intake and ports will help as well if you have EGR 403 code that is flagging/service engine light on. To change plug, you must remove the plenum, not as daunting a task as it seems, remove black plastic cover, bolts through plenum to block and you don't even have to remove airbox/flowmeter; leave attached and just pry/left up just out of way (but not too far too crack rubber hose from air box to plenum) to get to plugs, if truely foiled/need replacing. Replace plug wire at same time while you are in there. Good luck! Replies to this message: diamoney (Sep 15, 2007 11:00 am)

Replying to: jtkramer6 (Sep 14, 2007 8:40 pm) Thanks man.. I will give it a shot.. I actually went in and cleaned the throttle body, and valve.. It was a little tight in there, but I was able to smooth it out considerably... In regards to the plugs.. you were speaking about the spark-plugs correct? if so, can you clear it up for me.. I still am boggled about how to change them.. do i actually have to remove the upper to get at the rear plugs?? any help would be appreciated..
