For awhile my car If you run it for a period of time it goes hot but once I'm traveling it would cool off it says coolant fault yesterday it did the same thing due to sitting in heavy traffic this time it began to stall so I pull off to a fueling station to cut it off for a little then I start it up again it crank but once I attempt to change gears it cut off i notice that it was no coolant in it I towed it to my tire shop and he called and said that they ran something it showed errors like p0301 p0304 p2237 p2240 p0691 p0693 p0420 p0403, p130a and p1b1c60 he said he didn't handle f
Experienced mechanics share their insights in answering this question :
A low coolant level can cause overheating however there are lots of additional causes of overheating. Coolant leaks are easy to find via pressure testing. In the context of such a test, if pressure falls and yet no external leak appears it means there is an internal cooling passageway leak. As far as the OBD-II trouble codes that you were given, the ones listed implicate quite divergent systems ranging from misfiring to EGR to catalyst efficiency. A couple of the codes relate to the cooling system fans and could be important clues in light of the hot idling. As noted, all of the issues will have to be diagnosed. All of the diagnostics and the repairs can be performed on a mobile basis and so if you want to obtain the least costly repair, on a mobile basis, simply request a check engine light diagnostic and an overheating diagnostic.

The most common reasons an Audi A6 is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
2012 Audi A6 Check Engine Light Flashing

Substitute classic reasons for a Check Engine Light are faulty head gasket, dirty mass airflow sensor, faulty emissions control part, a malfunction with the fuel injection system, damaged oxygen sensor, or defective spark plugs to name a few.

Whether you are able to temporarily solve the problem or not overheating is a very serious issue. It can cause cracks in the cylinder head along with gasket issues that can in turn send coolant to the oil and be the beginning of the end for your engine.
A coolant symbol may appear on the dash with a warning “Fault Turn Off Engine.” DTC P1B1C00 may be stored in the ECM (coolant pump mechanical malfunction). The condition is caused by either a thermostat defect or the diagnostic software is incorrectly displaying the warning where no technical issues exist.
Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle`s cooling system.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.

Other common reasons for a Check Engine Light are dirty mass airflow sensor, a malfunction with the fuel injection system, damaged oxygen sensor, faulty emissions control part, faulty head gasket, or defective spark plugs to name a few.

That said, a severely overheating engine can cause the cylinder walls or the pistons themselves to warp, bend and deform. This will cause the perfect seal between the piston and the rest of the engine to lose integrity. Oil could be forced past the piston rings and into the engine, where it will burn the oil.
Your overheated engine may still be running, but it`s not fine. You risk costly damage to your engine if you keep driving. DON`T panic. Your engine may have lost its cool, but now is the time for you to keep yours!
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
In general, it`s because something`s wrong within the cooling system and heat isn`t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.

ANSWER : A low coolant level can cause overheating however there are lots of additional causes of overheating. Coolant leaks are easy to find via pressure testing. In the context of such a test, if pressure falls and yet no external leak appears it means there is an internal cooling passageway leak.

2004 Ford F150 crank no start, Happened 1 month ago and Yesterday , but it started today
ANSWER : There are several possible reasons for a vehicle to crank and not start. A bad fuel pump, clogged fuel filter, faulty injectors, bad ecu, failed ignition coil, or a malfunctioning sensor. It will first be necessary to figure out if there is a lack of spark, low/no fuel pressure, or a mechanical problem. Once you have figured out which of these is causing the issue, then you will need to figure out what component is causing the problem that is keeping the vehicle from starting. If this is something you feel you need a hand in diagnosing/repairing, contact a certified mechanic, like the mobile mechanics available at YourMechanic.com.

My car shut off while at a stoplight. I got it started only for it to shut off agin. It starts then shuts off.
ANSWER : Hello, thank you for writing in. The vehicle is stalling due to an electrical issue (typically pertaining to power supply or a sensor), a lack of fuel, or a failure with the ignition (spark) system. You will want to start by scanning the vehicle for diagnostic troubleshooting codes. Use any information found there to help guide you to the system or component that is failing. Without that information, you will want to test the fuel pump, ignition cables, spark plugs, and alternator function. Further testing may need to be done based on those results. For more help with diagnostics, contact our service department to schedule an appointment.

Changed battery and the fuel pump and car still slow to start. When it does start it shuts off without warning. Fuel filter is fine.
ANSWER : Hi there. The battery could be dead even though it has a full charge. There could be a dead cell or an over charged cell. Have the battery checked with a load tester. This will place a load on the battery and the battery is not to drop more than 3 volts during the test. If the battery drops more than 3 volts, then the battery needs replaced. Also, check the starter and ignition system for any faults. Look for corrosion on the ignition wires and see if the cables to the starter are loose. If you need further assistance with your no start situation, then seek out a professional, such as one from Your Mechanic, to help you.

07 xterra cranks but wont always start. sometimes starts and shuts off immediately. sometimes just cranks and cranks
ANSWER : The best way to diagnose a problem like this is to play with certain components and attempt to replicate the issue. Components that could be causing these symptoms are the fuel pump, fuel filter, a number of solenoids and sensors, faulty ignition coil, or spark plug. You should absolutely scan the vehicle for diagnostic troubleshooting codes. This would give insight to any sensors or electrical connections that have failed. This scan should be performed when you get the vehicle to start and is running. There may also be mechanical issues in the starting system that are less likely to occur, but can cause these issues. A full inspection of the vehicle is needed. I would recommend having a YourMechanic professional technician repair repair and diagnose the reason to why your car is not starting.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Car was sometimes not starting, not even cranking when i turned the key then after a few times itd start. Now it ont start at all
ANSWER : Hi there:

Without being there to inspect your vehicle, or having information about what type of car, truck or SUV you own, it’s very hard for us to give you some advice. You might want to have a professional mobile mechanic complete a car is hard to start inspection; so they can come to your location and determine why your vehicle is having these issues.

When I try to start it, it cranks slowly as in cranks like dead battery but then cranks just fine but won’t start
ANSWER : Hello, and thank you for writing in. To begin there may be issues with the wiring, position of the starter, a faulty starter, or an issue with the timing. However start with the simplest options and work you way up in complication. With replacement starters, it is often required to add a shim to the mount in order to align the starter correctly. If the gears are misaligned, or not making good contact, then the starter motor will bind or move slower. This may even result in a grinding. Secondly with a voltmeter you can test the voltage available to the starter and see if it is receiving the full 12 volts. If it is not, then you may have a bad wire, a loose connection, a dirty connection, an issue with the starting system, or a bad ground. If it is, then you want to look deeper into the alignment of the starter, and check if it was a re-manufactured replacement part. After you rule out a faulty starter you can then resort to the timing and other sensors. For more diagnostic help, contact our service department to schedule an appointment.
