The EGR valve opens and closes during the engine’s cycles. If the EGR valve is stuck open, exhaust gas cycles back into the chamber when they are not supposed to. The engine cannot combust on too much of the carbon dioxide in the exhaust gas, meaning there’s not enough oxygen for co...
It's usually triggered by a fault in the emissions system, which includes a broad number of issues from bad spark plugs and faulty catalytic converters all the way to a gas cap not being screwed on correctly. Because the Check Engine light is vague, it can be tempting to ignore it. But...

‘mayonnaise’ being found on the underside of the oil cap. This is essentially the water curdling with the oil and if left to its own devices could lead to the gradual overheating of your car. If the water temperature is steady but sits higher than it should from stock, this could be ...
remove the oil fill cap to inspect for brown milky goo that has collected on the bottom of the cap, which is an indication that coolant is leaking into the oil. Chances are the head gasket has failed, but if theengine has been severely overheatedit could have a crackedcylinder head, or...

A study by the innovation charity Nesta found doing so could cut your gas usage by about 9%.[9] Translated into cash terms, it means a typical home (a two to three bedroom house) might save around £65 a year under the new Ofgem energy price cap.[9] Be sure to check your ...
The first step is to open the hood. However, don’t forget that the engine should be sufficiently cool before you remove the radiator cap or reservoir cap. If theengine is hot, give it at least an hour or longer to cool down before you attempt to check the coolant. ...
