99 ford taurus starts up but doesnt drive more than 10 miles per hour and temperature starts to rise


maybe a coolant thermostat that is faulty, a collapsed or perished hose..

It could also indicate cylinder head gasket/cylinder head problems.

Ten miles is about the correct distance for a car engine to reach normal operating temperature. If your temperature gauge continues to rise beyond normal ..ie. overheating .. you risk causing a lot of damage to your engine.

If you're not sure what to do or look for - get somebody to check it out for you

Low oil pressure on 08 gmc seirra


With fuel injection if the pressure goes to low the fuel pump will stop and the lifters will get noisy.If you are seeing 10 lbs hot at idle I wouldn't worry to much.
If you have a high mileage vehicle and live in a warm climate,go for 20w50 oil at your next oil change,some use straight 40w oil to help oil pressure on worn engines.

Water pump...what would be a good estimate of repair cost and hours for a 1998 eclipse 4 cyl.


Good news is, that water pump is really cheap! About $30.00 locally here in Seattle at just about any parts store.

The other news...labor is what gets ya for this engine work. Guessing no less than 2 hours is what they would charge you...no less than $85 an hour at most garages....all together with the "other" charges they tack on...environmental disposal of the coolant and whatever else....close to $200-$250 for the job.

I Have my check engine soon sign on i have changed my transmission fluid and oil fluid yet the problem still persist. The major problem is that if i fire the car it cannot get more than 20/30 kil per/hr...


First thing i would change is your o2 sensor. you might take to autozone and let them check your codes that might tell you for sure what it is, This is a free service from autozone. Best of luck .

2000 v w 2.0 starts fine but goes dead immediately


If the engine cranks and fires, then runs for about 1 to 2 seconds, look for a 'Yellow Car' symbol in the cluster.

This indicates the ECU does not recognize the key transponder and denies a engine run command.

If this is not the case you may have a faulty fuel pump. Fuel pumps fail and just give a short pressure rise before they quit allowing the engine to get enough fuel to fire but not run.

Another problem with these is the oil pump. When the engine fires it runs the oil pump and if the dump in the oil pump is faulty, it builds too much oil pressure and forces the valves off the seats and compression goes away and engine stops.

High Oil Pressure ( Over 90 psi.) overpowers the hydraulic valve adjuster elements to the point they pump up holding valve slightly open.

Only cure is a new oil pump. It lives in the oil pan and is easy to service. Average time to change out would be 2 hours, unless you have a Cabrio, in which case lower shield needs removed adding another 30 minutes to an hour to the job.

2003 kia sorento will not re start after running around town


Engine temperature spikes when a car is shut down and many cars have an extra switch for the electric fan that will turn them on if the temp rises past a certain point.
That switch may have failed, making it necessary to allow the engine to cool off.
Your car may not even be equipped with that feature so I would suggest trying the following: When restarting soon after shutting off, slowly press the accelerator pedal completely to the floor and don't let up on it until the engine fires. Allow at least 20-30 seconds of cranking before giving up on it. The engine may be getting surplus fuel because of a problem with the computer or a 'cold start valve' that lets the engine draw more fuel when cold so starting it 'hot' it may be getting too much fuel to fire (flooding).
