SOURCE: My 2007 sierra is loosing about 1 1/2

Hi,
Sine you are concerned about the warranty timeline, perhaps you should take the car to the dealer and explain the problem. Hopefully the warranty will cover the repair.
The problem won't go away...

SOURCE: The service engine soon light is on. The check

Have the computer scanned if you want a quick scan have Auto Zone or the like scan it for free , they also will give you a printout of the problem code, if any, that may be stored in the computer system.
Trans. fluid is only checked on a running in park warm engine, if it is not running the fluid will read too high on the stick showing an overfilled condition, use only recommended fluid, should have the type requirements stamped on the transmision dip stick.
When filling do it slowly and add only half a quart at a time checking the level each time as to not over fill.
The trans. fluid and filter should be changed every 30,000 miles as preventive maintenance proceedures.
Hope this helps, good luck!!

SOURCE: low coolant level in 2003 yukon after radiator flush

When coolant gets drained and refilled air bubbles are often trapped inside the cooling system. If you imagine pouring a soft drink and you see all the little bubbles sticking to the sides of your glass, you'll get the idea. After driving those bubbles eventually "burp" their way up to the top, and consequently the coolant level drops. Top it up one more time and my guess is you'll be good to go.

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

Driving the car for about 4 hours a day,stop and go,i am losing 2 to 3 qts of oil. it looks like oil is leaking from above the upper oil pan on both sides.on the side obove the oil level sender,i see oil...


When was your last oil change? Was the oil filter correctly reinstalled. I'd take a run into a service shop and have them take a quick look to see if it is something simple.

Getting trouble code po868


transmission fluid low pressure detected. Root cause is either dirty transmission oil and filter or defective pressure sensor. If you are handy, they can both be changed (filter and sensor) in an afternoon, not expensive. A mechanic could change both in under 2 hours shop time on a sunny day.

I get the message "stop engine, oil pressure low"/


Are you leaking oil? Do you know for sure? When you turn your car off, if you check the dipstick the oil wont register until the car has cooled off. You also need to make sure its sitting on level ground in order to get an accurate reading. Try putting a piece of cardboard under your car to see if its leaking. leave it there for a few days. Wait an hour or so after you have turned the car off and check the oil level. Is it low? Is it normal?. Have you tried changing your oil to see if the old oil is lumpy or ruined? Are you using the right oil for your car?

Engine oil sprayed all over the bottom of engine after 7 miles of driving, pressure gage (on dashboard) turned around showing red arrow at the top. After a couple of hours started engine, no visible oil...


First check the oil level by means of the dipstick. If it hasn't got any oil it cant leak either. Under no circumstances should it be started without oil up to the correct level.

Hi i have a 1994 dodge caravan it is leaking oil can this be fix im worry that we would have to save money for a van for my kids thanks


The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

My Honda Accord 1996 Vtec Engine Oil Short after i travelled long distance


If you are saying your oil level is low, then you need to add oil to your engine. If you are concerned that the oil level was low after your long drive, it would depend on how long it has been since you added oil or even checked your oil level.Engines will consume oil over a long period of time. Especially if the oil is not changed according to manufacturers recommendations. Unless the low oil level was sudden I would not be concerned. If it happened suddenly and in a short period of time, look for an oil leak of indication of the engine burning the oil, such as smoke at the exhaust pipe.

My 2009 H2 is idling rough for 2-5 min with a cool start, after 2 weeks of doing this, its now blowing white smoke on the first start of the day for 2-5 mins, after that it runs normally, I have NO...


My guess would be a leaking intake or head gasket. Water in the cylinder(s) is shorting the spark plug until the temp comes up on the engine. The white smoke is the coolant being burnt off. check your coolant level it may be low.

What are some solutions for a 1994 Camaro Z28 Lt1 engine, that has hesitation when at lower speeds. Some sputtering happens also. Have tried the usual fuel injectors. Occasionally this problems smooths...


The rear seal of the intake manifold will leak but the sendinging unit for oil pressure is more likly. if it's just a light on switch just change it for general practice as their cheap and the distrubutor drive can leak but you need the swich removed to check this area as the valve covers leaking are the most common problem don'et overlook them as they leak in all kinds of ways. miles and or time tells me how bad a leak is you can let'er sit and the oil drain plug can leak a 1/2 quart but you don't even drive itand does it leak if it sits? can you look under thew car with it running and see it drip? a 1/2 quart leak is easy to find unless you drive real far in 3 days. Oil pressure sending unit ( bet-so)

Just had an oil change, two days later, the check


you can always take off your postitive cable, and negative welll just positive, Leave it off for about 3 to 5 hours. Then put the positive back on, this will reset your whole car. The check engine will come off but heres the catch you dont have much time probaby like 5 to 10mins before it comes back on. it work for me. Make sure the place your getting it inspected is close by maybe even do it near the place and then have them take it in from were you park. They will start it up, drive it in, turn it off. hook everything up. start it up again real quick to check if light goes on. It shouldnt. when I did it as soon as i left it went on. it was a close one.lol But give it a try and see if it works. Also dont forget to fix your time after reset, just in case some places get suspcious GOOD LUCK
