Hi there. Yes the engine is an interference design. This means that if the timing belt breaks the pistons will contact the valve train when not in time. If the belt has broken, I recommend testing the cylinder head and...

Hello Jacqueline! Thank you for writing in with this question. This problem could be related to a bad gas cap o-ring, or something more involved like an evaporative emissions system leak, or canister purge solenoid problem. Since the Check Engine...

I'm going to guess that you have a power steering pump belt that is slipping. The slipping belt makes the squeal and the slower turning pump makes the wheel hard to turn. Your car may just need a new belt...

Hello. The brake pedal going to the floor is a common symptom of a faulty master cylinder. The master cylinder will usually fail due to an internal or an external leak. In your case I believe the leak is internal...

Hi there, thanks for writing in. Your particular year and model of Subaru does not need to have the valves adjusted. It uses hydraulic lifters that are self adjusting. If there is a ticking noise, it could be that...

Hello - the lack of acceleration or speed over 20kpm is classic behavior for a failed throttle position sensor. I would find out specifically what codes are now being set before spending any more money on parts or repair. Most...

Hi there. There are a few sensors that can cause this as well as some mechanical issues in the transmission. Even though the Check Engine Light is not coming on I always start by checking the computer for any codes....

The problem can come from a few areas depending on the vehicle. It can be a loose ground to the instrument cluster, or a circuit board failure inside the cluster itself. Some vehicles also use an amplifier in the cluster...

Hello. It sounds like you may have a valve cover leaking. If it leaks, the oil can get on the exhaust and cause smoking, and if it gets on the oxygen sensors, then the car will run like this. The...

A cooling system that keeps getting low on coolant in a short amount of time has an active leak in the system. If the leak cannot be found externally then the leak will be internal to the engine. You will...

This sounds like potentially a mass air flow sensor problem. The mass air flow sensor monitors the air flow into the engine and when this is faulty can cause reactions much like what you are describing. I would suggest having...

Hello. Volkswagen's dynamic curved lighting does not utilize an extra bulb despite all the confusion out there on the topic. The headlights physically swivel 5-15° allowing drivers to see up to 90% better around corners. VW uses servomotors controlled by...

Based on the information given, it is very difficult to diagnose the issue. The chain dragging and lack of starting sounds to me like your timing chain has broken and needs to be replaced. Timing chains can cause damage to...

Hi there. Your vehicle's wrench light, Check Engine Light and lack of performance go hand in hand. The vehicle's PCM (powertrain control module) has recognized a fault and put the vehicle into limp home mode. It could be, a throttle...

It is possible an independent mechanic may be able to devise a fix for the wiring issue that the dealer would be restricted from doing as it may require modifications. One thing to consider though, modifications to the truck may...

Hi and thanks for writing to YourMechanic. There are several things to look at. First off, have the coolant tested and make sure it is within spec. If coolant is not mixed at the correct ratio, it can cause the...

Depending on the symptoms of the vehicle, this may be a transmission problem or a failing axle. Unfortunately, without additional detail as to the specific model of your vehicle, it may be difficult to diagnose without physically inspecting the vehicle....

In order to check your fuel economy you will need to fill your fuel tank completely and zero your trip meter and drive vehicle until you use at least a half tank of fuel and then fill the tank and...

Sounds like you may have a problem with corrosion in the transmission control module, shift module, or in some of the engine sensors. Reading the engine codes would lead to a more specific diagnosis, but checking for corrosion on any...

Hi there. The year, make, model, and mileage usually helps. However, I can provide you with some direction on your concern. If you're experiencing a wet spark plug, there could either be no spark on that plug or a leaking...

Hey there. This may suggest that the coolant fan relay switch may not be working properly. When you car is moving down the freeway at higher speeds, the engine gets a lot of cooling assistance just simply from the air...

Hello - from your description of symptoms, I believe you have worn steering or suspension links in your front suspension. The need to "correct" when turning indicates that something in the steering components is shifting, which should only occur with...
