Hi there. I have forwarded your inquiry to our sales and support team who should be contacting you shortly about your question. Thanks for writing in to YourMechanic.com.
The best thing to do is put the vehicle on jack stands and remove the tires to the suspension that is to be damaged. Then check the ball joints, control arm bushings, and the control arms and see if there...
Hello there, thank you for asking about your 1986 BMW 635CSi. It sounds like you've checked all of the low hanging fruit. The previous owner may be right - some vehicles (only German ones come to mind) can develop a...
Hi there - your symptoms suggest a problem with the transmission since they only appear when the vehicle is in gear. First task is to check the transmission fluid - you are looking for "clear" red fluid and no burned...
The door striker pin on the body side will loose the center plastic over time and when it is gone, then it will not push the door latch closed enough to lock and slamming the door is needed to get...
My guess is that the problem is with the body control module (BCM). The BCM functions as the power mode master (PMM). In this role, it receives an input from the ignition switch when the key is turned to the...
Hi there: This issue is commonly caused by three different systems, ignition system, fuel system and the emissions system components including O2 sensors and the EGR Valve. The best way to know for certain and before you spend any money...
The idle control is most likely sticking or has gone bad. If this is the case, then it would need to be cleaned or replaced. If cleaning the idle control does not work, I recommend having a certified mechanic, such...
It sounds like you may have some coolant that is leaking out, causing the motor to overheat. Or, you could have a bad thermostat or a faulty cooling fan relay that is causing the motor to overheat which is then...
Wow that is a lot of replaced parts. Assuming all the new parts are good I highly suspect a problem with either your cam or crank sensors. If either of these sensors fail your engine will not know when to...
Hi there, thanks for writing in about your 2011 Mercedes E550. This sounds like potentially a bad crankshaft sensor. I would recommend having the car scanned to see which trouble codes show up. More than likely, there will be more than...
Hello, thank you for writing in. A grinding noise when turning can come from the mechanical linkage that allows your steering wheel to turn the tires, or it can come from the hydraulic system that assists you in turning. Start...
Hi there. There are varied opinions about switching from synthetic oil to conventional oil. I am old school and believe you stick with the manufacturer's recommendation for oil type. Nowadays, most conventional oils are a synthetic-blend. I believe BMW recommends...
Hello, thank you for writing in. With the extent of the work you have done already, it leaves very few components left to consider. With that being said, take a few moments to verify that all of the repairs you...
The oil must be drained first. The oil pans on these vehicles are typically stamped steel and don't require the removal of any other parts other than a few brackets and fasteners to gain access to all of the oil...
Hi there. The Ford engine will not bolt up to your Mazda transmission, however, you can purchase a conversion plate that would allow the engine to bolt up to the transmission. If you do this, you will need to get...
You may still be in lockout and the security system is keeping you from starting the car. When the car was entered without the key, it no doubt triggered the immobilizer and that will have to be reset. It's might...
Hello, thank you for writing in. With the amount of work done on the air conditioning system up to this point, you may have introduced air into the system. Make sure the refrigerant is properly cycled out and recharged, rather...
Hello. If the car was running BEFORE you replaced all of these parts, the first thing to do is make sure that you have reconnected any wiring (harnesses, plugs, grounds) that you removed when you replaced the numerous items that...
Not the new ones, but the old ones were good, yes. Nissan Pathfinders were decent vehicles, but you don't want to get one that is all worn out. Those have a lot of problems with automatic transmissions. If you can...
The first thing to do is to see if the convertible top fuse is ok. Then you should check that the power to and from the top switch is flowing. If both are ok then the power top motor should...
The ABS and Traction control use sensors located in the tire area. There are hub bearings that are paired with sensors operation. The clunk sound could be some type of wear that needs to be look at as soon as...
You may be able to spot the leak by performing a cooling system pressure test. This test is just as it sounds; a special tool is used to apply pressure to the cooling system, making leaks visible. Sometimes however, leaks...
Hello - the lifter noise and loss of power are, I believe 2 separate issues. The noisy lifter problem is somewhat common on this engine - sometimes caused by poor oil supply (oil sludging). The loss of power issue is...
Hi, thanks for writing in. There are a few components that can cause these issues. The easiest part to inspect for proper function is the drive belt(s). If these are slipping, stretching, or breaking they will slip and can cause...
