Take the spark plugs out and fill the water up. turn over the engine. see what comes out of the spark plug holes. should just be fuel. smell. you will need some one to turn the engine over and have good charge in the battery. fill the water to the top so it is level. if you see the water go down when the engine is turning. then it could be air or a leak in the head gasket.

SOURCE: 1995 Mitsubishi Diamante is overheating. Oil

the symptoms are that you have a burnt head gasket, its consuming the water into the cylinders and at the same time it builds combustion pressure in the cooling system causing it to overheat, and when it overheats it makes the oil loose viscosity so you loose oil pressure, i recommend not driving the car any more and the first solution is to replace the burnt gasket, and change your oil, go to a local shop and only do these they probably tell you the engine is worn but the problem is what i told you above, make them replace the thermostat unit yes to be sure good luck

SOURCE: 2004 VW Bug leaking antifreeze. small puddles

the VW beetle has a plastic radiator, where the cap is if you look to the front of that it does a 90, it is cracked there. Here is the fun part, with a throx wrench ( I think it was a T-30) take apart the fenders and front bumper. At the auto parts store there is a plastic tank repair kit, the kit includes resign,fiber glass cloth, and a stick. You will need to rough up the crack as it is right where it angles and lay on the cloth and resign. Let it dry and it will not leak from there again. Good Luck Tim

SOURCE: the checj engine light on my 99 pontiac sunfire

first of all, was the water on the passenger side from the air conditioner or a leak (what color was the fluid?)-the cap has to be tight, otherwise it will not hold pressure, so that has to be checked before you set off again-push down as you turn the cap clockwise, and it will not hurt to have water in the system (it actually transfers heat better than antifreeze) but it has a much lower boiling point, so the cap has to be tight. Pay attention to the temperature gauge and do NOT overheat it-it is an aluminum engine and they do not tolerate excessive heat. Take your time, no AC (although the AC being on can keep a good cooling system more stable since the radiator fan is forced on when the AC is running, so you can, within reason, experiment)-no matter what, just don't let it run hot-not worth it.

SOURCE: 2003 Hyndai Elantra oil light has started flickering, Why?

If it flickers at idle, it "might" be engine wear, especially if you are approaching 200,000 miles. It might also be a faulty oil pressure gauge sending unit which is a little more likely.

Can low coolant in car lock up your engine


Low coolant will cause overheating- damage to your engine- depending on how low it actually is. If the coolant is less than four years old you could just add coolant (you can buy premixed at the auto parts store) to the proper level. More than four years old and your coolant should be replaced; and the system flushed in the process. If you are just adding coolant, be sure you are using the proper coolant for your car.

Light brown junk in radiator


I suspect you have a leaking cylinder head gasket, this would account for the gunk in the system. To confirm this is the problem have a shop that owns an exhaust gas analyzer put the probe in the coolant recovery or surge tank of the system and see if any combustion gases show up in the system with the car running, do the test both hot and cold engine states. You will be looking for hydrocarbons. No matter what the outcome you must have the system professionally flushes and clean uncontaminated coolant installed Ina proportion of 50/50 coolant to water mix.

I have a 97 Chevy Lumina. It has 276,*** miles on it. I bought it used 4 months ago. It was running excellent then the service engine soon light, low coolant light, and change oil soon light started coming...


The fact that the oil was low would not be from the oil pump, but from wear in the engine. If it is not smoking when you start it or as you drive, you can probably keep it running by just keeping the oil level checked at each fuel fill-up. As for the car shutting off, you didn't say if the engine seized or got real hot. A low oil pressure problem should have triggered a warning light before the problem got to the point where you lost the engine.

If the car ran after you added the oil, you got lucky and need to always check it.

2005 mazda 3 2.3l that is burning oil (no leaks)


possibly the pcv but check if your cars exhaust smoke is blueish or white in color if it does and your car doesnt have an oil leak then sure its burning engine oil along with fuel, the piston rings is defective, since you replaced engine oil the additive that the owner has put with the oil to prevent blowby is gone thats why it starts burning oil.....

I have 97 4runner sr5 (not 4wd) it has 244K miles on it - i took it in for an oil change and i was told that it is recommended that i get an "enging flush" and also a "radiator flush". I just checked out...


The only engines I have ever seen that needed to be "flushed" were engines that had used Quaker State oil for a long time. Usually about the only good way to tell is your engine is gummed up is to remove the oil pan of the intake manifold and see how much residue is built up in the engine. If your radiator has rust in it and the cap & gasget have rust deposits on them and or the overflow resivoir tank has rust in it thenn I would say to drain and flush the coolant system. If there is no rust, the coolant is the orinigal coolant color and the engine is not overheating it does not need to be flushed. Follow the reccomendations of the coolant manufacturer as far as to the length of use before draining and replacing with fresh coolant.

Coolant level low light comes on and coolant level is not low in reserve tank or radiator.


There is a TSB for this problem. Here it is.


Bulletin No.: 04-06-02-007

Date: August 11, 2004

TECHNICAL

Subject:
Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination)

Models:
2000-2002 Buick Century, Regal
2000-2001 Chevrolet Lumina
2000-2002 Chevrolet Impala, Monte Carlo
2000-2002 Pontiac Grand Prix
2000-2002 Oldsmobile Intrigue


Condition

Some customers may comment that the low engine coolant level indicator is always illuminated.


Cause

The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.


Correction

Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.


Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of "aftermarket" over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin.

1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL(R) mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin.

2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section.

3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light:


^ Light is on - Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI.

^ Light is out - Proceed to Step 4.



4. With the key off, connect the coolant level sensor into the vehicle's wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.


^ Light is on - Replace the low coolant sensor and re-check system operation.

^ Light is out - Proceed to Step 5.


5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Re-install the low coolant sensor into the vehicle and proceed to Step 6.

6. Flush the cooling system and install new DEX-COOL(R) mixture as outlined in the SI. Check the vehicle's warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination.

What's going on with my Chevy Lumina?


I remember my wife's old Lumina had the head gasket replaced and hearing about the TSB (technical service bulliten) on the engine. Check your engine oil and coolant.....if the oil looks milky (whitish brown) or the coolant looks like it has oil in it, you may have seroius engine damage. If the oil and coolant looks ok, get a few estimates on replacing the intake gasket, but don't gamble that it will resolve you issue.

If the cost of the repairs are more than half the value of the car, it's time to let it go...
