Hello. From what you are describing it seems as though the transmission fluid has leaked out. There is a rubber hose that conveys transmission fluid to the radiator for cooling (through a sealed heat exchanger). That hose could have leaked....

It sounds like you may possibly have a bad neutral safety switch. Your vehicle has a neutral safety switch (https://www.yourmechanic.com/services/neutral-safety-switch-replacement) that will prevent the vehicle from starting when it is in any gear position other than park or neutral. Occasionally,...

This is due to a possible blown head gasket near the number 6 cylinder on the engine. You have aluminum heads and may have a crack in the head. I would recommend having the system checked by a certified technician...

This may be a sign of a vacuum leak. A vacuum leak can be one of the most frustrating and difficult problems to diagnose. High idle speed is a common sign and stalling is another. Confirmation of an engine vacuum...

If these symptoms did not exist prior to replacing the timing chain, a possibility is the valve timing is off because the new chain is mispositioned. You can get an indirect indication of incorrect valve timing by measuring engine vacuum....

The noise is most likely coming from the clutch release bearing and when pressure is put on it the bearing it is binding up. You may need to have the clutch and release bearing replaced.

As a colleague of mine used to say, "everything works, but the hands don't move," He used that expression when he had checked everything on a certain system and found it to be working correctly, but the system was still...

If you lost all power while driving and now have no power to anything then you need to check the main battery cables and alternator for voltage drop on the cables using a volt meter. This will tell you where...

Hello, thank you for writing in. There are several reasons the gas pedal may become unresponsive. The first step is to have it scanned for diagnostic codes, to find out what issues the vehicle's computer has detected. This will narrow...

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...

You most likely have a coolant leak into the engine through an intake or a head gasket leaking. If you have water in the oil it may damage the crankshaft bearings if ran too long with the water in the...

You most likely broke the clutch or transmission input shaft gear. This most likely happened when you started the engine without pushing in the clutch. The normal way was to push in the clutch to start the truck. Now you...

If this is the factory air cleaner assembly then I suggest looking for it on ebay or at a salvage yard. Otherwise you would need to replace the entire unit with an aftermarket one.

You should have the fuel pressure checked when the vehicle stalls to see if you are losing fuel pressure since you notice the pump is noisey when running. The pump is most likely losing pressure when it gets hot and...

I suggest you verify with the mechanic since they may be referencing the motor mounts front and rear but they are also called transaxle mounts when parts are looked up. The engine has one main mount in front of motor...

You have a total of 4 mounts. There is one front engine mount and two transaxle mounts then there is a torque mount on top front.

Cold weather also makes cable action stiff...
