How To Clean An Electronic EGR Valve

Disconnect the negative battery cable. By removing the negative battery cable from the battery, you ensure no current is flowing through the system and avoid short-circuiting the electronic component that controls the valve.

Disengage and remove any sensors and electrical connections along with any hoses.

Loosen the bolts to remove the EGR valve and gasket.

Check the hoses and gasket for wear, to replace or reuse.

Spray the valve and hoses with carburetor cleaner, using a brush to clean off the carbon buildup out of any hoses and small hole with the pintle. Do NOT spray the electrical connections or sensors with the cleaner. However, you may want to purchase a can of electronics cleaner and di-electric grease if the connectors appear to be corroded.

Reinstall the EGR valve using the gasket and bolts, and reconnect the electrical connections and sensors with any hoses.

Reconnect the negative battery terminal.

Transverse Vs Longitudinal Engines: The Pros And Cons

The way in which an engine is orientated can have a huge influence on the rest of a car’s design. Should the car be rear-wheel drive? What size of engine is expected? Are there space issues that could influence which way the engine lies? All these questions have to be answered by the engineers responsible for the car, as the powertrain setup can have a large impact on how the car goes, handles and stops. Looking at front-engined cars, the two possible orientations are longitudinal and transverse, with each having its own benefits and drawbacks that can govern which is chosen for the car at hand. In-light of this engineering decision, here’s a basic guide to the features of each engine layout and which is best for different applications. Transverse engines Transverse engines are mounted perpendicularly to the direction of travel, lying horizontally within the engine bay. This is predominantly used in front-engined, front-wheel drive setups but has also been implemented i...

SUVs That Think They're Sports Cars

SUVs have long since evolved past the idea that they should be all about rugged off-road experiences requiring four-wheel drive, locking differentials, high ground clearance, and the sheer and utter ability to go absolutely anywhere. In many ways, the SUV category has become just as varied as the passenger car category. With this revelation, it comes as no surprise to find a number of SUVs on the market with driving dynamics chief among their palette of attributes. Yes, there really is a very credible slate of SUVs that think they're sports cars. Here's a list of them. Acura RDX Updated for the 2016 model year, the sporty Acura RDX luxury crossover SUV is an extremely competent handler with strong acceleration and a thoroughly modern look. Key features include Smart Cruise control, lane keeping assist, and remote engine start. The 3.5-liter V6 engine has been upgraded to produce 279 horsepower and 252 ft-lbs of torque (up from 273/251). A six-speed automatic is standard, a...

Mods To Do On Golf 4 1.8T

The order of these mods is recommended, although everyone decides to go down their own path. 1. Maintenance before modding - This includes changing fluids, spark plugs, filters, timing belt, Making sure your brakes work etc ... Some cars may need more maintenance than others, but It's never a good idea to start a modding a car that has not been properly maintained. 2. Catch Can - A catch can be a great preventative mod that will reduce the amount of carbon build up in your engine. Our PCV systems are a known problem, and carbon buildup becomes a big one issue that reduces power in our cars. Although a catch can not completely fix the issue, it will definitely help. Pairing one with the occasional sea-foaming will help keep your valves clean and carbon free. 3. Downpipe (DP) - The reasons I put these two categories together is because they are go hand in hand. I will explain each one individually later on. The stock DP on the mkiv 1.8t is very restrict...
