The quick answer is no you should not use 5w20 when 5w40 is recommended by manufacturer. The thinner oil may not lubricate the internal engine as designed. The turbo also needs synthetic oils to withstand the heat of the turbo....
Closing the trunk is very easy. Here’s how to do it easily and safely: 1. Locate the trunk inner handle, which is on the inside of the trunk, near the latch. 2. Pull the trunk down with the handle until...
Hello, a coolant leak with no external leaks leads me to believe you might have an internal leak at the head gasket. The first thing to do would be to check the oil and see if it looks like chocolate...
Hi there. If you are having a low oil pressure on the gauge, put a mechanical gauge on the engine and check for oil pressure. If the oil pressure is 40 psi or higher, then the engine is fine and...
There are a few possibilities as to why your window will not come back up. First could be a bad window switch. Next, would be a failure of the window regulator or motor. This issue is not uncommon. I would...
The PATS system cannot be bypassed. You are required to have a coded PATS ignition key in order for the computer to turn on the spark and fuel to the engine. If you do not have a PATS programmed key...
There is a technical bulletin for your vehicle to replace a tube to the turbo for oil control. The turbo leaks oil past the seal and this will emit smoke from the exhaust when the engine is cold and sat...
Hello. Hyundai is one of the vehicle manufactures that is utilizing the electric power steering systems. This means your vehicle may not have a power steering pump, fluid reservoir, or hydraulic assisted steering. They are doing it with gear reduction...
Hi Rob. Thanks for the question today. There are literally a dozen or more possible reasons why your DeVille is acting in this way. Sometimes failing wheel bearings will create the vibration you're explaining, while in other instances, loose motor...
Hi there. there are typically two reasons why this occurs. I have seen this happen simply because the vehicles computer needs to be updated. If the programming is off it can cause enough of a delay in shifting to where...
It is unlikely the battery terminal connection is a cause of the fault you are describing. If they have actual evidence of a fault related to the "connection", they should have provided that information to you. If no evidence is...
If your engine loses oil pressure or the oil pressure sending unit fails for some reason, such as a bad sensor or wiring connection to the sender the engine control module, this will shut down the engine and not allow...
Unfortunately, I cannot give you an answer as to what exact part to change. Code P260F relates to the evaporative system. Simply put, gas fumes from the fuel tank have to be burned away. These fumes are vented forward to...
The express power windows make it easier for you to open or close your windows. To use the express power window feature, press the window switch all the way down, or pull the window switch all the way up, and...
Engine overheating with AC on is generally caused by one of two possibilities. One, is increased engine load caused by a failing AC compressor. The AC compressor adds rotational load to the engine and if the compressor is wearing and...
Transmission Failsafe means that the transmission controller has detected a problem with the transmission or any of it's sensors that is preventing it from working properly. In your case it seems to see a problem when you attempt to get...
Usually when the alarm fails to go off you can pop the hood and disconnect the negative battery cable. By doing this you should be able to stop the alarm from going off. I would recommend leaving the battery unplugged...
In order for a catalytic converter to function without overheating (and melting and clogging) unburnt hydrocarbons in the exhaust stream must be kept below a relatively low "threshold". Normally, the amount of these unburnt hydrocarbons, which represent wasted potential energy...
Hi. There are multiple individual parts that could be causing the squeaking noise on your 2003 Toyota. In fact, the tie rods and shock mounts are leading candidates for causing the squeak (when you hit a hole) and the suspension...
Hi there - excellent work, I commend you on your diagnostic skills! Yes, based on your description and testing, I would agree that the fuel pressure regulator is the most likely candidate for this problem. Bear in mind that a...
Yes, absolutely, rebuild or replace the engine. The vehicle itself is a recent model year so your least cost option will be to repair what you have. And, you're right, "re-sale value" is irrelevant in the calculation (good for you!)....
The first thing to check would be the transmission fluid level. If the fluid level is low from a leak, this may cause the transmission to slip and when revved to higher rpm it may jerk when the line pressure...
Hi there: Based on your input, there are a few items that you might want to have inspected by a professional mobile mechanic to determine what's causing this shaking issue. First would be the tires and wheels for balance. Usually...
The battery terminal connections should be inspected since they were serviced recently. These are often left loose, or even applied too tightly. Allow me to explain: Some people tend to turn the securing fasteners on batteries until they cannot...
The starter may have a "dead spot". When you crank the vehicle, power is sent to the starter solenoid. The solenoid extends the starter drive gear to make contact with the flywheel to crank the engine. Once the engine is...
