Question about 1999 Buick LeSabre

3 Answers

200 miles from home change oil soon light came on, after getting home car ran hot, and my husband had to bypass the heating system with a hose, to be able to use the air conditioner still, the oil had been changed 5 days before the trip of 1200 miles or so. I normally use 89 octane, but on the road used 87, at one station had to use 92 because they were out of the other grades. after driving home from work putting water in as needed until I get the heater coil, I can not get the car to crank, the lights for the brakes comes, on with a few other dash lights and the security light. what do we do to get the car started again, my car is a 1998 buick lesabre limited

    my car will not start, it is turning over like it is going start but it doesn't.
    does putting different grades of gas matter?

    You know what I have no idea what your question is, to much info, what is the exact problem, the oil change has nothing to do with it of that I am sure.

Well here is the real solution. Gas and bypassing a heater core have nothing to do with this. This is not a spark pug issue niether. Your security liggt is on for a reason if you have the older style key where you can see the resistor (black chip with a wire crossed it) then the wire broke in the column.comon problem. Go to radio shack and get the resistance of that chip with a multi meter then buy a resistor of the same resistance for about 99 cents next go under your das at the base of the column and cut the very very thin yellow and orange wires and splice your resistor in. That will take care of the security issue and you will be able to start the car.

If you are still having troubles try just replacing ur spark plugs. the may have become fouled. my parents were having the same trouble with their car and that fixed it

Okay kThe oil change and octane rating of gas used has nothing to do with your starting problem. I sounds as if you have bypassed the heater coil, and you do have a leaking problem. If so you may have overheated your engine and if so, you need to go to a auto tech, and have a indepth diagnosis done.

Have a 2001 saturn 3 door coup drove it with out oil cap on and when noticed oil was dry it only took 2 quarts to fill wondering what kinda damage it could of caused


Damage could be extensive or light.......depends on if you ran it with the oil light on or pressure dropped?
What does the oil look like when you stick it after it's hot? Get that oil filter off there now and replace the oil with a good quality 5w-20 ,a new filter, and a can of `Sea-Foam' engine oil additive. and run it easy.
The new oil should lick up the tarry stuff slowly,if it has any.If you notice ANY DROP IN OIL PRESSURE, check the oil right then and there.
You'll have to do an oil change again soon,say less than 200 miles to be safe.don-ohio

Reset oil change milage


GM OIL LIFE SYSTEM - RESETTING
The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.

Reset the oil life monitor when the oil has been changed, use the following procedure:
  1. Turn the ignition key to the RUN position.
  2. Fully push and release the accelerator pedal 3 times within 5 seconds.
  3. If the Change Oil Soon light flashes, the system is resetting.
  4. Start the vehicle.
  5. The oil life will change to 100%.
  6. If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.

My 2006 BMW 525XI was working fine all day and then I went out to air dry the car after i hand washed it this evening and as soon as I left the driveway I heard the radiator fan kick on and within I mile...


I assume you have checked the cooling system to ensure that first, that it is completely full of coolant (not just the overflow tank) with no air locks and second that there are no leaks anywhere and the radiator cap is in good condition. The heater hoses and those pesky little bypass hoses in the cooling system tend to go hard and split after a few years, allowing coolant loss. Those spring type hose clamps tend to be less effective in clamping as the hoses become hard. Worm drive ones are the best to use.

If there are no leaks or air locks, the over heating could also be caused by a clogged radiator (more than 15% restriction in the radiator flow capacity will cause overheating problems), a faulty water pump or a faulty thermostat.

If there are no leaks and water pump and thermostat are working correctly, but undetected loss of coolant once the engine heats up, then it could indicate a problem with the head gasket (Usually caused by allowing engine to become excessively overheated when cooling system has run dry) allowing very hot high pressure combustion gases into the engine water jacket, which super heats the coolant in the engine block, which then boils off, and is released via the cap. If the head gasket is really bad it will leak water into the cylinders and into the oil in the sump. This is indicated by an emulsion of water and oil mix on the dipstick.

If unsure take vehicle to a cooling system specialist and have them do a pressure test and more thorough diagnosis.

Overheating problem


looks like you have done everything but the problem with your car is that the cylider head gasket has gone have a look at the dipstick or remove the oil filler cap if it looks like mayo then 100% head gasket has failed you said no water on the floor so it must have gone into engine only way this can happen is head gasket failing, if you have put lot of water in to the cooling system then your sump will be full of oil water mix.

let us know your findings so we can help you more if you need it

No heat in 2000 chevy lazer just replaced thermostat


I own a 200 Chevrolet Blazer and I have it for over 4 years mine does the same thing I actually just noticed my heat getting less. My husband found the best way to fix it and the cheapest way to fix it. He takes the tube off the heater and attaches a water hose to it and flushes out the gunk whatever is blocking the hose and after he does that the heat works great. No cost and if I wanted to I could do it because its so easy. My husband did some searching on the internet and a person that this happens all the time to let me husband know. If you need more info let me know I can ask my husband he isn't home at the moment I so I don't have exact details. Thanks Amy
