While disconnecting the fuel pump relay and running the engine will work, there are other alternatives. If you can access the Schräder valve, depress it to release the pressurized fuel before disconnecting the fuel lines. This will have the effect of reducing fuel line pressure. It helps to have the vehicle cool down and not running for a few hours. I ...

I would use epoxy primer to start. You can then spray paintable undercoat on your frame, underbody. They come in various forms as depicted in the image below. You may also use a rocker guard type product as shown. To my personal taste, I would seal with epoxy primer, rubberized undercoat, and then oil undercoating to protect even further. Application ...

The one tool you will need to purchase / borrow is a Volt Ohm Meter (sometimes called a Multimeter). Then you need to use it to read voltage AT THE BATTERY, before the car is started and after the car is started. My guess is you won't see any voltage difference. Before the car is started, I would guess you'd see voltages like 12.6v or so. After the car ...

You are correct in how to do this. I was just watching an episode of "Tech Garage" and they were talking about this very topic. Their suggested methodology was to pull the fuel pump fuse, and run the engine till it stopped on it's own. You can now change out the fuel filter. You will still get some fuel out of the line, but nothing like having 30-60 psi of ...

I would bet the engine in your car is drive-by-wire, which means the computer is controlling the throttle, not you. In doing so, it is going to look at the load put on the engine and a bunch of other factors and give it only the throttle it can use as well as the gas ... at least in high gear. By going WOT in this instance, you'll not be causing your engine ...

I'm guessing you've got a 13 psi radiator / cooling system cap. The 13 PSI number is pretty standard for GM cars. At that pressure, water doesn't boil (from liquid to vapor) until 245 deg F or so. What you are seeing is totally normal. The manufacturer uses those pressures to improve radiator vehicle cooling performance. If while driving on a hot day ...

On the upper control arms are two eccentric bolts for adjusting caster and camber. In this image the knockouts for camber/caster adjustment haven't been removed. And would need to be either cut out or use a special tool made by OTC. You need a camber gauge and plates or an alignment machine to set camber. If the camber on the bolts are maxed you ...

The thermostat opens at 180 degrees F, this sets the lower limit. The fans come on in low speed mode at 223 degrees F. The fans come on in high speed mode at 230 degrees F. So temperature can and will vary between these values. In cool weather when driving at higher speeds the temperature should be in the lower end of the range. On hot days with the A/C on ...

The last time (many years ago) I changed out a turn signal switch it was a PITA because of all the anti-theft devices wrapped around the steering column. By the time I got to the switch I was cursing up a streak and I never did get the thing back together right. Never again. With airbag systems on the steering wheel it can only have gotten worse. My advice ...

According to this website, the coolant capacity for the 2007 Chevrolet Spark is 4.2L (4.4 qts) for the 1.0L engine. If your vehicle differs from this, you can cross reference on that page to get your specific vehicle. You can use whatever type of coolant you desire (red, green, yellow, orange, etc.), but realize each has its own change interval. It will ...

It all depends on what temperature the thermostat is designed to regulate the coolant at, which usually depends on what pressure the cooling system is designed to operate at. Water boils at 212 deg F at atmospheric pressure but will boil at higher temperatures under pressure. This is why it can make sense for the fan to turn on at 223 deg F; the coolant ...

This feels like a broken blend door. A blend door controls how much air is allowed to flow past the heater core, or past the a/c evaporator. A broken door means that air physically stuck going past the heater core, thereby heating it up. Unfortunately, those doors live inside of the heater box, which usually requires you to rip apart the dash (and then ...

This sounds like a stuck or faulty heater circuit valve. There's a pipeline from the engine coolant system that goes up to a heat exchanger in the air conditioning duct. There's a valve that regulates how much hot coolant flows in this circuit, and if that valve sticks open or its actuating linkage is broken, the system will be on hot, hot or hot - No matter ...

First drive a bit and measure the temperature of the wheels with a gauge or even by touch. Whichever are hotter, that side is jamming. Then based on that, remove the wheel, and remove the caliper. Typical caliper consists of 2 pins that it moves on and one piston that pushes against the inner pad. The pins is what you are after. They should be easily ...

A 3 wire CKP sensor would produce a 5v square wave. A 2 wire CKP sensor produces a AC sine wave. Even if you managed to wire the 2 wire sensor to the 3 wire harness the car wouldn't start. You would have to swap the tone wheel if they're different.
