The first thing I check for in any drivability problem is air leaks. Any air that gets into the engine without going through proper channels will lean out the system and cause these kinds of problems. Look under the hood...
Engine coolant can leak externally through a hose, radiator, water pump, etc. or internally due to a leaking head gasket and sometimes a leaking intake manifold gasket depending on the engine design. External leaks are typically found by simple pressure...
Hello. I'm sure this is been done but ensure that the clutch release bearing and a whole clutch kit was installed when you replaced the clutch. A complete couch job consists of a pressure plate, a flywheel, a clutch disc...
This is a very broad question with little information to go on. The most common causes of overheating are low coolant or the engine cooling fan clutch since your car has a mechanical fan. More information would be required to...
The best thing to do is to have your cooling system checked to find the cause of the broken tube. The system may have other issues that would need addressed at the same time. That being the case, I recommend...
This sounds like you started off with the coolant getting low due to a leak and then it got worse when overheated and blew the head gasket causing the misfire and no starting from coolant getting inside cylinders. You will...
What you are describing sounds like a dirty or failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and...
Hi Eugenia. Thanks for contacting us today. Oil leaking into the spark plug wells is an indictor of a fairly serious problem that should be inspected and repaired immediately. It is almost always due to a failing gasket or O-ring...
The check engine light indicates that there is likely something wrong with the engine or transmission in your vehicle and will usually come on in conjunction with the vehicle going into the reduced power mode. This happens when the vehicle...
This may be a sign of a vacuum leak. High idle speeds or in some cases rough idle, stalling and hissing sounds are common signs of a vacuum leak. When a vacuum leak is present in an engine, this causes...
The cost of YourMechanic inspections, diagnostics, and repairs are based on industry standard and cataloged "repair times". In other words, the price you pay is calculated based on an industry standard "average" time that it takes to perform the specified...
Hello, thank you for writing in. Testing for oil burning usually means opening up the engine to see if the pistons and exhaust manifold show signs of oil. You can also check your spark plugs to see if there is...
The crankcase is a closed system and this kind of test does not show anything on this cars engine since if you open the oil cap the engine will run rough due to sucking in all the fresh air. The...
Hello, thank you for writing in. The automatic transmission starts in first gear always. Considering the age of the vehicle, there are a large number of components that can be contributing to your symptoms. Start with the simplest fixes. When...
Hello. If both of these have not worked since the transmission was replaced then I would start by checking all of the connections that were taken off during the replacement. It is possible that there is a bad ground connection....
Hi There, The transmission in your BMW 525i is what is called a "sealed unit" which means that the transmission should not ever need to be flushed or have the fluid changed. This means that in the event you may...
Hello, thank you for writing in. While it is not terribly uncommon to run transmission fluid in the power steering system (they are both hydraulic fluids), newer vehicles tend to be designed to be used with specific fluids, and do...
Hello, the turn signal/emergency flasher unit is a black plastic unit - rectangular, golf ball size - located just left and under the steering column. The lower portion of the steering column black plastic cover, and potentially the left knee...
Hi there. If the fuel pump relay is getting hot, then check the condition of the fuel pump when the key is on. If there is no sound at the fuel pump (like a hum), then the fuel pump maybe...
Diagnostic Trouble Code P0444 does not identify a fault that would cause the power loss you are describing although once the fault causing the power loss is repaired P0444 should still be resolved of course. The other code, namely P1892,...
