Tech Feature: Tips for Servicing Performance Carburetors
Carburetors have been around forever, and are still the dominant fuel mixer for most circle track, drag racing and street performance muscle cars.
Tech Feature: Breezing Through Ignition Off Draw Tests
One of the biggest differences in servicing the Sebring convertible from other Chrysler models was its battery location – behind the driver’s side wheel well.
Tech Feature: Oil Pump Technology
Oil pressure is something every engine builder worries about. Low oil pressure or a loss of pressure can cause expensive warranty problems and catastrophic engine failures, neither of which is good for your business. Though the “bigger is better” mentality persists, most engines only need about 10 psi of oil pressure for every 1,000 rpm of engine speed.
Tech Feature: Ford Hybrid Braking
A hybrid vehicle is a different animal than many of us are used to seeing. After all, if the engine of a typical vehicle were to stall out at a traffic light, the driver of that vehicle would know something was wrong with it. If that same vehicle still drove with the engine off, then that would mean they were probably going down hill. But in the hybrid world, that is all normal. Several systems around the vehicle are impacted by two key elements.
Active Safety Technology: Adaptive Cruise Control, Lane Departure Warning & Collision Mitigation Braking
A vehicle that stops itself may sound like something out of a futuristic sci-fi movie, but the technology is here and now. From collision mitigation braking to adaptive cruise control, find out how many of today’s next generation active safety systems come into play.
Tech Tip: Servicing a Malfunctioning Automotive Ignition Switch
The automotive ignition switch, formerly a straightforward device used to connect battery voltage to various circuits and prevent theft of the vehicle, has recently been switched up.
Tech Feature: Manifold Makeover – Increasing Engine Power
An intake manifold is more than the plumbing that connects the carburetor or throttle body to the ports in the cylinder head. It is an integral part of the induction system that has to match the airflow characteristics of the cylinder head and camshaft, as well as the displacement and rpm range of the engine. A well-designed manifold that is properly matched to the engine’s requirements will make more torque and horsepower than a manifold which is mismatched to the engine.
Tech Feature: Returnless Fuel Injection Systems
If you’ve tried to find the fuel pressure regulator on many late-model engines by looking in the engine compartment, you won’t find it there because the regulator has been relocated to the fuel tank. Engines with “returnless” electronic fuel injection (EFI) systems have the regulator inside the fuel tank. The regulator is part of the fuel pump assembly and is usually located downstream of the in-tank fuel filter.
Tech Feature: Servicing Supplemental Restraint Systems
KABOOM!!! That’s kinda fun on the holidays isn’t it? Well, the pyrotechnics in a car can be satisfying as well. Satisfying to your wallet that is. I’m sure you’ve heard how "dangerous" air bags can be. Well they can be dangerous, but at the same time, they are pretty safe, too. An electronically controlled air bag requires a sufficient voltage and ground supplied to it or it will not detonate. Notice I specified "electronically controlled." There are some older models that were ….
Mustang Tech Tip: Oil Leak or Oil Weepage Can Result in Burning Smell
Some vehicles equipped with the Romeo 4.6L 2V engine or 5.4L 2V Windsor and 5.4L Supercharged engine may exhibit an oil leak or oil weepage from the cylinder head gasket at the right-hand rear or the left-hand front of the engine. Oil weepage is not considered detrimental to engine performance or durability. An oil leak may be caused by metal chip debris lodged between the head gasket and the block, chip debris between the cylinder head and the head gasket, or by damage to the cylinder head sealing surface that ….
