Jacking instructions for this vehicle are on page 439 of the 2016 Toyota Corolla Owner's Manual (https://www.toyota.com/t3Portal/document/om-s/OM12J84U/pdf/OM12J84U.pdf). Note that steel safety stands MUST (must) be placed under the vehicle once it is jacked up. Hydraulic jacks can and do fail...

Hi Patel. Thanks for contacting us tonight. While synthetic oils are typically longer lasting than a conventional oil, the engine and ECU can't predict or detect the oil in the engine. This is why the warning light illuminates. I still...

Hi there. Check the condition of the coolant and see if its full and new. I recommend putting a new radiator cap on and putting in a new thermostat. Once a thermostat is introduced to the atmosphere after being submerged...

Hi Steve. Thanks for contacting us today. In most cases, these two codes (one from cylinder 3 and 4) are caused by a failed ignition coil or a faulty electrical connection. The first thing I'd do is double check your...

The vibration is not normal and probably reflects an imbalance in a rotating engine or transmission component. Once engine speed and gear, at the time of the vibration, is known, that might help to narrow the diagnostic and in a...

Vibration felt through the steering wheel at high speeds is often due to tire imbalance/tire defects although worn suspension components can be a contributing factor. If ball joints have failed early, there are only a handful of possible explanations for...

Hi Renee. Thanks for contacting us today. The Shifter Position Switch and Neutral Safety Switch are one in the same, but I don't think that's the source of this type of problem. Typically when that component fails, it causes all...

Hi Justin. Thanks for contacting us today. At first glance, the numbers you listed indicate that the catalytic converter is likely clogged. You might want to read this article about the OBD-II trouble code you've listed (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker), as it will...

Check inside the air filter housing and if it is not there then it is built into the mass air sensor on this model.

A likely cause is a loose or worn suspension component. There are other possibilities but if you were to request a diagnostic that is where the investigation would begin. As far as whether the noise represents a normal characteristic of...

If the part listed is a genuine Toyota oil filter, it is very likely that the oil filter is the same one they would use at the dealership. This tends to be the highest quality available. It would meet the...

If you are using an aftermarket tensioner, that is not a Toyota OEM part, that might cause some difference in the manner of operation. Also, be sure that the belt is the correct part number and measure the belt tension...

He's correct in that the sienna catalyst is integral with the exhaust manifold. That is done by the manufacturer to ensure that the catalyst reaches operating temperature as quickly as possible. It's not true of all cars so your friends...

The reason the heat was working intermittently is once the coolant starts boiling within the cooling system, the boiling action creates an impediment to normal coolant circulation to and through the heater core. So, ironically, even as the engine is...

If the converter is functioning, the voltage output from the downstream oxygen sensor should be somewhat steady at around half a volt. What you seeing in the car with the P0420 code (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) is a high-low voltage signal from the...

Hi Sahil. Thanks for contacting us today. If the clutch plate alone was replaced, it's possible that either the clutch is not correctly adjusted or the faulty component is something different. It's best practices to replace the entire clutch pack...

With regard to the dealership, or any mechanic for that matter, simply ask for the evidence substantiating the diagnosis and proposed repair. In the case of an alternator, once the drive belt is removed from the engine, and the engine...

When you turn the key to the run or start position, the immobilizer warning light on the dash will typically illuminate briefly as a bulb or system check. Once the vehicle starts the immobilizer light, and all other warning lights,...

My best guess is that the crankshaft bolt worked loose and as it became more and more loose the front pulley and maybe the timing belt sprocket started knocking around. Once the bolt became loose enough that the front sprocket...
