Egine flooding after changing coolant sensor switch and down stream oxygen senso


Hi rowdy the problem need to involve a scanner. Check the readings KOEO of the coolant and the the o2 sensor write them down. Reinstall the old sensors back check the reading write them down. Comparing the reading. Start the vehicle if it start let it run for the engine to get his normal temperature. Check the reading KOER. If the reading stay the same check the wire from the sensor to the pcm for.short to ground or open or short together. If there is no short to ground no short together no open the pcm need to.change.

Why is my add coolant light on


your coolant light is on because there is not enough coolant in the radiator. When the coolant is hot it expands and the excess water is pushed out into the reservoir and as it cools down the water is sucked back in and so keeps the top tank of the radiator full. However if you have a leak or a faulty radiator cap the water comes out ok but instead of sucking back in water it allows air in instead. Therefore you have a one way circuit of water out but no water back in. Your coolant light is telling you to check out the fault before you over heat the engine

Replacing a cylinder head gasket is a miss or a hit. In some cases, just replacing the gasket may work. But if the cylinder head is bend, dealer may ask to replace it, because "machined aluminum heads rarely works". In this case the cost may be more than $1000. It is a good idea to send the cylinder head for inspection, in a machine shop. They charge $150 for inspecting, checking, cleaning and if necessary machining the head.
If the timing belt will be replaced this is an extra cost. If someone will just replace the gasket, on a bend cylinder head, it is more likely to blow out again. This problem can be solved if the gasket be replaced properly, checking and taking care for the cylinder head too.
As the coolant warms up, it expands and for that reason you have two marks at coolant bottle. Down cold and up hot. It is normal for the coolant to overflow from coolant bottle, if it is filled to the upper mark with engine cold, way up the cold coolant mark. Let engine to cool down overnight and set the level at coolant bottle at the lover mark cold. If it will overflow again this is a bad sign. The pressure at combustion chamber varies from 75 in idle up to 150 or more in higher RPM. If the cylinder head gasket is blown, then gases are blown into the cooling system, increasing the pressure, the radiator cap pressure relief valve is open and coolant is discharged in the coolant bottle. In such cases it is common for the coolant bottle to boil. You can observe gases discharging in the bottle, mixed with coolant, from the cooling system. These are symptoms of a blown cylinder head gasket. Because you replaced it once, there might be a bad (bend, deformed) CYLINDER HEAD too.
To find it out you have to perform cylinder compression test on your car (PROFESSIONALLY).
1. Start with a normal ("static") compression test. To eliminate rings, valves, holes in pistons, that sort of things. A normal cylinder balance test is also helpful (so you know which, if any, cylinder is presenting a problem). Engine should be warm.
2. Put all spark plugs but one back in. Ground that plug wire to prevent module damage. Disconnect that injector on a port fuel system.
3. Put your compression tester into the empty hole. The test can be done without a Shrader valve, but most people recommended leaving the valve in the gauge and "burping" the gauge every 5-6 "puffs".
4. Start the engine and take a reading. Write it down
5. Now goose the throttle for a "snap acceleration" reading. Reading should rise. Write it down NOTE: Don't use the gas pedal for this snap acceleration. The idea is to manually open then close throttle as fast as possible while without speeding up the engine. This forces the engine to take a "gulp" of air.
6. Now write down your readings for at least the bad cylinder (if there is a single bad cylinder) and maybe 2-3 good ones. Make a chart like this: CYL STATIC COMPR IDLE -RUNNING COMPR - SNAP Cyl 1 150 75 125 Cyl 2 175 80 130 Cyl 3 160 75 120 Cyl 4 160 80 125
7. ANALYSIS: Running compression at idle should be 50-75 psi (about half cranking compression). Snap throttle compression should be about 80% of cranking compression.
Consult a professional with the readings. If the gasket is to bad, you may have very low compression at lease in one cylinder.
If you will get a positive confirmation for a bad cylinder head then you have two options:
REBUILD THE CYLINDER HEAD or REPLACE IT.

I have a 99 ford ranger 4x4 and its overheating and ive replaced the rad,waterpump, thermo, and hoses and its still overheating but not all the time its random


Hello! The most important question is what type of coolant are you using? There is a Technical Service Bulletin (TSB) #01-23-6...It relates to the only coolant that can be used in your Ford...Do not use coolant made with Propylene Glycol...It will damage the cooling system...Only use Ethlene Glycol based coolant...Since you have replaced all major components and still have a problem...I would suggest back flushing the engine block...A back flushing kit can be purchased at most auto part stores...The random nature of the overheating may also be associated with electrolysis...Using a digital volt meter set to read less than 1 volt...Put positive probe into recovery tank and negative probe to ground...Start engine...Any reading over .3 volts is indication of a problem...Electrolysis turns coolant to goop and will not circulate...Send results...Guru...Saailer

I want to change coolant fluid on my Durango 2002. One bottle of antifreezze will be enough to mix with water?


This depends on the capacity of the car and the type of coolant you purchase. Read your owners manual. It will tell you the capacity for your car. Most coolants you buy are a 50/50 mix meaning they need equal parts of water to coolant. Make sure you read the coolant instructions. Hope this helps

Screen on dash says "coolent low".


Sounds like a bad thermostat. A malfunctioning thermostat will back up coolant into the overflow. BTW, are you experiencing any problems with the heat or AC? This would also be an indicator that the thermostat is faulty.
