Question about 1997 Mitsubishi Montero

Power steering problem, noise coming from engine, 97 montero

1997 Mitsubishi Montero LS, 4x4 150K miles.
all belts including timing belt have been replaced in last 3 months, water pump replaced 3 months ago. alternator replaced two weeks ago.

There is a strange noise coming from the engine area, somewhat of a clanking, clicking sound, sometimes with chirping. the engine seems to run fine, but the power steering froze up and its nearly impossible to steer. when parked and i move the steering wheel from side to side the power steering pulley and belt (and all the other belts too) come to a complete stop for a second, go slow and then start up again when i release the wheel. it doesnt seem like its just the power steering motor thats frozen and the belt is slipping around the pulley, its like all the belts freeze up. from underneath the car, it also seems like the crankshaft isnt turning smoothly, as if its rubbing or scraping on something. i thought i noticed some light metal shavings or dust coming from there.
any help is greatly appreciated!!

Your experiencing the same thing my 02 is experiencing- your crankshaft pulley is slipping on the crankshaft. It only does it under load, i.e. turning steering wheel(loads the power steering pump) running heater blower on high with headlights on (loading the alternator) or running the a/c with blower (loading the a/c compressor and alternator). Turning off all lights, blowers, ac, etc and allowing the car to idle should kill the slipping until loaded again. This problem is very serious and very expensive if your don't catch it early. It require repairs ranging from tightening the crank to pulley bolt, to replacing the pulley AND your crankshaft if it is allowed to continue. if you cannot get it serviced immediately then do your best to keep loads off of your belts by driving with the blower off, A/C off, and lights used only when necessary. Also try to avoid extreme tight turns which load your power steering pump. Your repair, if not done asap, will cost you upwards of around $3k since the motor must be removed and completely torn down to replace your crankshaft and pulley. I would seek a tech who will exhaust every other method- i.e. sleeving, welding, etc. to effect a repair. Just don't put it off because it will only get worse...

2000 montero sport: There's a loud squealing noise coming from the engine. What could be wrong?

Squealing is most common with loose or worn belts, I would start by replacing the drive belt on the front of the motor and go from there, Its easier to troubleshoot a squealing motor if you know that the belt or belts are good.

My Mitsubishi Endeavor (2005) has run 60000 miles. I am going to change Timing Belt. Is Water Pump actuated by the Timing Belt ? So does it make sense to change the Water Pump at the same time? Thanks in...

Yes indeed, the water pump is driven by the timing belt on this vehicle and you would be well advised to change it and the idlers while you are at it. You can get timing belt kits for this vehicle that include the belt, 2 idlers and the water pump. In the UK, the kit is priced at about £70

When to change timing belt on 2003 mitsubishi galant

Most timing belt suppliers recommend 50k to 60k miles for replacement. Your Galant has a interference engine meaning that if the belt fails your will incur major engine damage up to and including replacement of the entire engine.

So if you have over 60k miles on the car go ahead and change the belt, and while you have it apart replace the water pump.

Your water pump is driven by the timing belt; to access you will need to remove the forward portion of the engine (pumps/alternator/belts and such) when replacing the water pump you wll need to remove and then replace the timing belt and tensioner. Much care is needed to to insure the proper timing or things can go very bad. On a scale of 1-10 (1 being the easiest) I'd give this a 6.5 to 7.

I hope this may have assisted you,

At what mileage should I change the timing belt on a 2004 Mitsubishi Outlander. Thanks Sherry

It is suggested by any mechcanic to perform this maintenace every 80,000 miles if you properbly maintain your vehicle. That mean going by the owners manual suggestions. Also I would highly recomend changing the water pum as well for it runs off this belt and water pumps only last as long as the belt will also. If a new belt is installed without a new water pump it may fail in no time. I seen it happen more than a dozen times in the past ten years

Should I change timing belt/water pump

Your 1997 Toyota with the 3.4 L V6 is an interference engine. This means if the belt breaks serious engine damage will occur. The belt must be replaced at 90,000 miles or 10 years under normal conditions and 60,000 under severe conditions. So, you need to have the belt replaced immediately as you are over the maximum of the belt's life. I would not drive this vehicle anywhere except to a trusted mechanic to have the belt replaced. The same belt that drives the cam also drives the water pump. In order to replace the water pump the cam belt must be removed. For that reason and the fact that the pump will not last 180,000 miles I highly recommend you have the water pump replaced at the same time as the cam belt. This will save you on labor cost later on when the pump would fail. Plus it might save more if the engine overheats. As you are going to replace the water pump this is a great time to drain and flush the cooling system and replace the thermostat which may or may not have been done in the past. You also will need to replace the spark plugs if that has never been done. Remember this is an INTERFERENCE engine. Keep driving the vehicle without replacing the belt and you are driving a time bomb that can explode at any time. Hope this is helpful to you.
