Volvo xc90 frequently asked questions 2003-2014 at the swedish auto parts store gasbuddy nj


It is common to see water coming out of the tailpipe in the morning. Most of time water accumulates in the exhaust system due to the difference in the exhaust to air temperature that occurs overnight. This condensation is common and only happens upon initial startup. electricity drinking game The only time to be concerned about that water coming out of the tail pipe is when the water begins to have a sweet smell. A strong sweet smell is an indication that there is a headgasket issue causing coolant to leak into the combustion chamber which then gets burned on startup. gas prices going up to 5 dollars This burning of the coolant creates a sweet smell that goes away within a few minutes (once it is all burned out of the cylinder where the leak occurs). In most cases you can determine which cylinder the leak is in by removing the spark plug and looking down into the cylinder. If the piston is silver and not black then that is a good indication that the steam created by the coolant being burned is actually cleaning the black carbon (created from burned fuel) from the piston top. If you see this then there is definately a problem with coolant leaking into the combustion chamber of that one cylinder.

The exhaust system is designed to carry away the engine’s exhaust gases with a low flow resistance, low noise level and a long operating life. The exhaust system has two parts: a front part with a catalytic converter, and a rear part with one or two mufflers. gas efficient suv 2013 Mufflers are a combination of resonance and noise absorption material. The exhaust system is held up by rubber mounts and uses clamps to connect the main parts.

In Most cases faulty Converters can be identified by noting that your Volvo will not accelerate or seems to have severely diminished power. Many times converters that are clogged up will glow red when your Volvo is running. grade 6 electricity unit test The reason for the Glowing is because of the amount of heat and unburned fuel that collects in front of the clogged up converter. Converter replacement is the only option. A quick way to be sure that the converter is the problem when it is suspect is to temporarily disconnect the exhaust system at the header and allow the exhaust to flow without going through the converter. r gasquet If the converter is the problem the cars power should be restored with the header pipe temporarily disconnected.

A harsh smell coming from the exhaust can usually be attributed to the use of fuel that contains methanol (Although in most places it is not supposed to be sold). gas in dogs causes When using this fuel, a sulfur smell can be emitted from the exhaust which can range from a mild odor to a rotten egg smell. To avoid this smell try changing the place where you purchase fuel! Catalytic Converter failures can also cause this same smell!

The most common Exhaust failures are mufflers. You can often easily diagnose issues with the exhaust system by placing a rag or towel over the tailpipe hole (Just for a few seconds). electricity and magnetism study guide 5th grade BE CAREFUL AS THE EXHAUST MAY BE HOT!!!!! When you cover the tailpipe hole up for a few seconds pressure builds in the exhaust system and a whistling noise will begin to occur wherever your exhaust leak is.

Turbocharger failures can be attributed too long between oil changes or the lack of oil in the engine. The turbocharger runs at very high speed so the lack of oil will quickly cause overheating and destroy the bearing. Long distances between oil changes cause "Coking" in the turbo lubrication areas which will lead to bearing failure. It is highly recommended to replace the oil supply line when replacing turbochargers. electricity vs gasoline The reason for this is because poor lubrication to the turbo is sometimes caused by a gummed up oil supply line to the turbocharger.

Other problems that can cause Turbo failure is inlet restrictions from dirty air filters, collapsed hoses or undersized air pipes. The less air intake by the engine causes the exhaust to heat up leading to cracking and scaling of the turbine housing. This can also be caused by over fueling the engine. Hot engine shut downs can lead to oil leakage by causing oil to coke up in the oil drain and forcing oil out around the turbine and seals.

Turbocharger failures can often be identified by noting that Small puffs of grey/white smoke begin to stream from the tailpipe when coming to a stop. This is usually an indication that the clearance between the impeller shaft and bearings have become excessive allowing oil to leak past the seals. Another indication of excessive bearing clearance is noting that large amounts of oil show up in the intake manifold.

NOTE: In most cases you can pull the hose that goes to the compressor side (silver aluminum side) and see if the veins on the turbo shaft can be moved manually. If not, the turbo is seized and must be replaced. Keep in mind that some failing turbochargers will only lockup once the engine is running because the veins will jam against the side of the compressor housing once the turbo spools up.
