2004 Chevy Trailblazer Variable Timing Solenoid Oil Coming Out
The VVT or variable valve timing is and always will be one of the most noted breakthroughs in the history on automotive innovation. In modern cars VVT systems are used for improve performance and fuel economy by altering the valve lift event. This is what allows just the right amount of oil supply, this allowing the engine to give great and fuel efficient performance. It is a system that uses electronic technology to apply variable electronic systems through a variable valve timing solenoid.

The variable valve timing camshaft actuators may stick due to dirty engine oil or a faulty control solenoid. A sticking actuator may cause a rough idle and the check engine light to illuminate. Our technicians tell us the engine oil should be checked to make sure it is clean and at the proper level before replacing any parts to correct this concern. If you already own a Chevy TrailBlazer or GMC Envoy or perhaps thinking of purchasing such a vehicle, then you have come to the best TrailBlazer and Envoy site on the net! Rainier, Bravada, Ascender, and 9-7x owners welcome too! Or sluggish cam solenoid or old oil. But you eliminated those possibilities. Chevrolet Trailblazer Variable Valve Timing (VVT) Solenoid Replacement costs between $128 and $172 on average. The parts and labor required for this service are.
2004 Chevy Trailblazer Variable Timing Solenoid Oil Coming Out Of Light
In case this VVT solenoid goes out of order, improper lubrication can cause a lot of damage and disruption to the gear and the timing chain.When this problem occurs with Variable Valve Timing Solenoid, many symptoms are bound to manifest this fault. Symptoms of a Bad or Failing Variable Valve Timing SolenoidHere are the symptoms that you must look out for to know that the VVT solenoid is failing or is not functioning well:SEE MORE.1. Check Engine Light OnThis is the thing about modern cars that the ECU or engine control unit starts to warn you as soon as it finds some problem in the engine. It can, in fact, practically monitor all the individual parts of the car.
So, in case of an impending, it is due to war you with check engine light. Variable valve timing solenoid failure due to engine lightIf this happens, you must contact your car service provider and have an ASE certified mechanic check it. They can certainly help you diagnose the problem. Dirty Engine OilThis is one of the variable valve timing solenoid symptoms that are also the cause. The VVT solenoid system performs the best with clean engine oil. When the oil has a lot of impurities, it loses viscosity.
This can also cause clogging in the variable valve timing solenoid system, thus also clogging the chain and the gear.If you see dirty engine oil, chances are that the VVT solenoid system is going out of order. Roughness in Idling EngineThe passing of additional oil to the VVT gears is a possibility if the system is not working properly. This very phenomenon manifests itself in the rough idling of the engine. It is primarily because the engine’s RPM fluctuates as the VVT starts working.
When this symptom is ignored, it can cause premature wearing out of the engine 4. Decline in Fuel EfficiencyThe function of the VVT is to control the open and shut timing of the valves so as to maximize fuel economy. Any malfunction here can cause wastage of fuel or dip in performance. If you notice decreased fuel economy, chances are that the variable valve timing sensor or some other part of the VVT system is failing.Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. How to Replace Variable Valve Timing (VVT) SolenoidOnce you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
Not doing so can cause totally unpleasant results like plummeted engine performance, untimely wear and tear of the engine, and visibly decreased fuel economy.So, follow this and let’s learn how to replace it. Here are the Things that You’ll Need Solving out Variable valve timing solenoid problems. Service manual.
Pry bar – 18” long. Pick set – long set. ¼” sockets – metric and standard. ¼” ratchet.
¼” extensions – 3” and 6”. Bungee cords – 12”. Channel lock pliers- 10” or 12”. Flash light. Needle nose pliers. Dielectric grease-optional. Box of rags.
Lithium grease – assembling lube. Telescoping magnet.
Ratchet. Extensions – 3” and 6”. Sockets – metric and standardVariable Valve Timing Solenoid Replacement ProcessYou can replace it in 10 careful steps. How to replace a variable valve timing solenoid 1.
Opening the Hood and Engine CoverStart by raising the hood and keeping it secured so that it stays up. If there is an engine cover, go ahead and remove it. The latter will be either secured with nuts and bolts or snap fastened. In both cases, it is pretty easy to undo it. Disconnecting the BatteryDisconnect carefully by loosening both the terminals. Now simply twist and pull to remove. Make sure that you keep the cables aside by preferably trying them down with a bungee cord.
This assures that they don’t come in contact with each other. Locating the VVT SolenoidIt is located near the front of the valve cover, i.e. In the front of the engine itself.
If you take the new solenoid and try to locate something that looks similar, things will be easier. You will be able to see the connector that lies at the exposed end of the variable valve timing solenoid. Once you have found it, use bungee cables to clear the area of any wires or harnesses. Locating Mounting Bolts and RemovingUsually there is just one bolt that you will find. In some cases there will be two. Look at the solenoid’s mounting flange to check.Remove these bolts carefully and store in a safe place.
Make sure you don’t drop it in the engine compartment while undoing. Looking for a high-quality used car from Japan. Tsukasa Azuma is an awesome car blogger of Car From Japan.
