I have a 2003 Saturn Vue w/3.0l engine. Had a coolant leak at the head gaskets. Had the heads checked for straight and cracks. Replaced the timing belt and water pump. Now while running I have a flashing check engine light, codes p0300,0301,0303,0305. replaced the coil, checked the timing marks 3 times, all is ok. Will pop through the intake on accel.

Check to make sure plug wires are the correct firing order, on right plugs.

SOURCE: car won't start

Only a few basic things are necessary for the engine operation 1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)
Plus, to start the engine, the battery, the starter and the starter circuit should be OK.

If the engine won't start - there's no magic - one of these things is probably missing. Most often it's a spark- or fuel- related problem, but often it could be very simple things like dead battery.
If the car won't start, check simple things first:
Make sure you have a fuel in the tank, oil in the engine and the battery is OK, follow this link - How to check the battery
Now simply answer the questions, press "Yes" or "No" (If it's blue, follow the link).

- Do you hear the cranking sound when you're trying to start your car? (Yes No )
- When you switch the ignition ON before starting a car, does the "check engine" light come ON? (Yes No )
- When you switch the ignition ON, do you hear fuel pump buzzing sound from the gas tank area? (Yes No )
Before your engine died, did you experience any prior events such as:
- leaving the lights ON overnight (Yes No)
- driving through a deep puddle, or washing the engine compartment? (Yes No)
- trying a jump start? (Yes No)
- having only a little fuel in a tank? (Yes No)
- having had the engine repaired recently? (Yes No)
- the engine was overheated? (Yes No)
- extremely low oil pressure? (Yes No)
- unusual noises such as knocking, pinging, whistling? (Yes No)
- smoking from exhaust pipe? (Yes No)
- strong smell of a gas? (Yes No)

Now, let's try again. Turn off the radio, try to crank the engine one more time, and listen carefully. Is the cranking sounds different than it used to be? If it's different, does it looks like the engine being cranked by the starter too slowly? (Yes No)
Is the engine being cranked too fast? (Yes No)

Hope this may help;

You could have a leaking water pump gasket. Did you put sealant on it when you replaced it? were ALL surfaces totally clean?

1996 Saturn sl2 coolant problem I can't figure out how I'm losing coolant no leak engine runs hot but when I shut car off and let cool coolant gone just about thermostat replaced


Blown head gasket and/or cracked head, cracked or leaking intake manifold. Since the car has run hot, the headgasket is probably damaged either way. On a 4 cylinder engine you are looking at $900 to 1200 range...v6 add another $3 to 400. Possibly more depending on what caused the failure in the first place.

What is the average labor time to do the head gaskets, water pump, and timing belt set on a 2003 Sarurn Vue v6?


I have to say head gaskets on a 3.0L VUE is very uncommon. Perhaps you could have the shop who is working on it explain it better and you could follow up because I have seen exactly 1 VUE 3.0L head gasket leak.

Labor to do the water pump and timing belt should be around 4 hours. Maybe a little more if the water pump leaked and made a mess they need to clean up.

Head gasket blown, water in the oil is a good indication, pull the spark plugs and see if there is coolant in the cylinder, do a compression check.

Oil in coolant system and all over under carriage and engine.


it seems there are some o-rings or seals which leak oil into the cooling system via the oil cooler. its a common problem. you can do a compression test, al cylinders should be 130lbs or better. then re try the test but add 1/2 ounce of oil to the sparkplug hole before testing each cylinder. if theres alot of increase in compression, your rings are geting bad. if theres little or no change, its likely valve seals. if theres little change on one or 2 cylinders, its a gasket or cracked head or maybe a burnt valve. if the change is between 20 and 40 lbs thats about normal for a 40K engine

Oil leaking into cooling system but no coolant in crankcase, also oil leaking from engine as it is all over frame and oil pan. engine starts and runs but heater does not get warm...??? 2003 saturn vue with...


Looks like a head gasket failure. Oil is escaping out of the engine and within the engine into the coolant passageways. The oil pressure system is run at higher pressure than the coolant pressure and fortunately this has so far kept the water from entering the oil and crankcase. I have no faith at all in any after-market product that claims it can repair leaks by simply adding it to the coolant or oil and taking a head off is not a trivial task. It may also be that the head has warped (this would also cause the leak) and this in turn will require it to be re-machined. Head gaskets are not expensive but due to the work involved this could be one occasion when a visit to a machine shop is the best option.

Leaks


the only thing that causes this is a blown head gasket or a cracked block, the head gasket is the most common problem, the block being cracked rare/

Oil leaking into coolant system


OK this can be 2 things. Either a blown head gasket which can produce oil in your coolant and over heats the engine. The 2nd is less likely and that is that your radiator and oilcooler both are leaking.
My guess is the head gasket. Good luck this will cost you quite a bit.
