SOURCE: auto transmission

The transmission in your car is the F4A33-1 model.I rebuild these transmissions and many others very similar to it on a regular basis.There are several areas that can cause the symptoms you are experiencing,and the first thing that should be done is a scan tool acquired for pulling trouble codes and looking at transmission data real time.If any trouble codes are present,they should be diagnosed and repaired.A faulty PRNDL switch,or faulty speed sensors (pulse generators) can cause your symptoms,and they are mounted externally on the transmission.If they are faulty,trouble codes will be present,and operation can be monitored with the scan tool by looking at the data stream.All of these external items have to be checked for proper operation.If all external items and controls are ok,there are 2 other problematic areas with this transmission as well as all Mitsubishi's,and that is the solenoids mounted on the valve body.The valve body is mounted inside the lower trans pan,and the solenoids on top of the valve body.They go bad on a regular basis,and i replace them ALL with brand new Rostra solenoids.The other problematic area is the 4th gear clutches,and the clutches and drum can be removed from the trans,and the trans doesnt have to be pulled for that.The 4th clutches and drum is located behind the side cover.They are very thin,and relatively small,and burn up easily.With all those bases covered,the only thing left to check good or bad is the transmission internally,or a computer problem.Mitsubishi's computers from those year models were very delicate and went bad often.I have a remanufactured computer in one of my Mitsu cars.Good luck.

SOURCE: My radiator hose exploded.

DOn't repair it, it is a wate of money. It got exploded since it got clogged the the pressure built up attcking w weak point due to aging causing the problem. You can change it your self to save labor cost of $100. The radiator cost $199 at autohaus online. At store will cost more. You should be thankful for this incident. Otherwise if it didn't go this path, it will attack you head gasket then it will cost more to fix. Have you heard about a blown head gasket? This is what i'm talking about. Cheers.

SOURCE: leak where lower radiator hose connects to engine

Real easy. The hose is held on by a jubilee clip. Best bet is to remove the hose (it will mean the radiator and block become drained of coolant) and clean the outside of the metal tube on which the hose is mounted. Sometimes corrosion here leads to leaks so scrape clean and polish with wire brush. Ensure that the hose is in good shape and that its interior has no bits of corrosion or dirt clinging to it. Slip the hose on to the tube and tighten the clip up. Refill the cooling system with a mixture of 1 part glycol antifreeze to 2 parts water. If in the Northern states make that mixture a ratio of 1 part glycol to 1 part water. Ensure the filer cap is on type and run engine up to operating temperature. Squeeze the top hose to help expel any air bubbles from the system. When the engine has cooled again check coolant levels and top up to make up for the expulsion of trapped air.

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

HI, I WANT TO BUY A MITSUBISHI DIAMANTE 97 130000 MILES. WHAT DO YOU THINK ABOUT THIS CAR? THANKS.


Main problems are computers failing ( especially the one that controls the auto) and random wires breaking.
If it has been looked after and had regular oil changes should be good for another 30 to 80000 miles if maintained properly.
Look for black oil and smoke on over run , Old radiator missing fins, rusty radiator water which should be green or blue ( signs of neglect)

Leaking radiator fluid where lower hose connects w/core


Hi:

If you have a leak near the lower radiator connection that just started, it is either a failed hose, or possibly a radiator core leak that is dripping down to that area.
If you havent changed your radiator hoses for awhile, and they feel soft, it isn't a bad idea to change them both. If you drain your radiator to change the hoses, this would be a good time to inspect the radiator, and perhaps you will find the source of the leak.

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

I have a 98 Mitsubishi Diamante that I just got out of the shop. I had the starter, alternator and 2 belts replaced. Less than a week later, I'm having more problems. When it was in the shop, they...


Was the cap on correctly when you opened up to refill it? To verify a leak clean up any residue that is on the engine etc and let it sit...then check for anything on the ground, chassis and at any hose connections. Check for leaks cold and hot. When hot there is pressure in the system and may reveal leak, however, many water pumps leak better cold with the cap removed (pressure actually will push the seal against the shaft and stop it from leaking) " It's leaking and I don't know where" isn't a statement I'd ever permit to pass me by...My next question would be, show me where. That does nothing to instill confidence in that shop.
One note: if it does turn out to be a pinhole in the radiator, believe it or not, a tablespoon of black pepper actually works. Just don't use more than two.

Follow the lower radiator up to the engine. It's in the housing at the end of it.
If you're overheating/loosing coolant, you may have a leaking heater core.
