Hi there. What you’re asking for is not a free recommendation that we offer. Plus, since we do not offer repair services in the US Virgin Islands, we can’t come to your location to help you complete the timing set-up for your 2000 Volvo. What I can recommend is to purchase a service and repair manual for your 2000 Volvo L4; as in this manual should be the step-by-step instructions for setting up ignition timing and completing most common repairs. Thanks for contacting us.

The luxury of your Volvo S40 is unmatched. Do not let a faulty timing belt for Volvo S40 affect your ability to enjoy driving your car. Turn to AutoZone to get the parts you need to keep your vehicle completely operational.
The S40/V50 T5 (one of the several variants) features the 2.5 L B5254T3 (later B5254T7) (2521 cc) five-cylinder fuel-injected engine with a high pressure turbocharger. The valvetrain has four valves per cylinder and is a DOHC design.
When to replace the timing belt? Every 60k-90k miles. If an engine is equipped with a timing belt, the timing belt must be replaced at the service interval specified by the vehicle manufacturer regardless of whether or not any problem is visible, typically in the range of 60,000 to 90,000 miles.
The best overall version, though, is the 147bhp 2.0-litre, five-cylinder D3 150hp diesel, which has impressive performance and still-reasonable emissions and consumption. On top of which, this Volvo-designed engine is generally more reliable than the Ford-sourced 1.6.
Volvo S40 Models

An entry-level luxury sedan, the 2011 Volvo S40 is a safe and practical ride that exudes class.

Cambelts or timing belts usually need to be replaced, usually between 40,000 and 100,000 miles. Alternatively, for lower mileage cars, the belt is advised to be replaced around four or five years.
A modern Volvo vehicle will typically need a timing belt replacement after around 100,000 miles, but some models may require the service at approximately 60,000 miles; driving habits play a role, too.
The 2022 Volvo S60 Recharge T8 Polestar Engineered is the fastest Volvo ever made, as it does 0-60 mph in just 4.1 seconds and has an electronically limited top speed of 112 mph.
Most modern turbos are reliable, but they all require some special care, like the type of oil and change intervals.
Timing belts are a serviceable item and should be changed as per the manufacturers` service schedule, this is usually between 60,000 and 100,000 miles or 5 – 7 years.
Seven years is the maximum life of the timing belt recommended by most manufacturers. For example, the belt should be replaced even if the engine has only 30,000 miles but is seven years of age. More timing belts break due to age than mileage.
It is safer to replace the timing belt even earlier than the manufacturer recommends. In general, however, timing belts needs to be replaced from 60,000 miles up to 150,000 miles.

At times my jeep will start fine and at times I have a hard time getting it to start. It seems like the wireless ignition node is
ANSWER : The recommended diagnostic to resolve this is a hard starting diagnostic. The work is performed by a certified mechanic right at your location. Among the first things the mechanic will check is whether required maintenance is up to date because old spark plugs, clogged fuel and air filters, and the like are potential causes of the hard starting you are describing. Other possible causes include a failing coolant temperature sensor, or bad connection to the sensor, problems with other sensors such as the cam and crankshaft position sensors, a defective fuel pump, and many other causes, all of which will be familiar to YourMechanic’s experts. With regard to the fuel pump, if the engine is not getting enough fuel it will be hard to start. If you request a hard starting diagnostic, YourMechanic will get this issue diagnosed and resolved for you.

Timing chain positioning
ANSWER : This system is a bit complex. I can give you some instructions, but I highly recommend getting a hold of a repair manual or purchasing a yearly subscription for just your vehicle from AllData. It is only $25 for a years subscription from AllData.

There are two separate sets of marks on this system. One set is for aligning the timing chain to the camshaft gears and the intermediate shaft gear. There will be marks on the chain that raps around the crankshaft gear as well. These marks will not line up after you turn the motor over.The other marks are on the inside of the camshaft gears and align with the cylinder head parting line. If you were to draw a ling through the center of both camshaft gears, they should line up with that imaginary line.

The crankshaft key way should be aligned with the mating face of the main bearing cap. You can confirm it is in the correct position by verifying the number one piston is at top dead center. If you have removed the balance shaft timing chain, these marks really need a visual diagram to understand where they should be aligned. Without a diagram I am not very confident it can be explained very clearly.

This may be difficult to to follow, so again I highly recommend purchasing a repair manual in digital form or a book. If you feel this is over your head, I recommend the following inspection to help you out. Timing chain replacement

Good luck! I hope I was able to help you.

hi- i got an estimate to replace my timing belt and water pump for my 2012 pilot. Do these figures seem right? Timing belt (35.00)
ANSWER : Hi there. That is a fairly good and detailed estimate for this type of service. It also falls within the price estimation to have a mechanic shop complete this service. However, you might want to consider a third option, of having a professional mobile mechanic come to your location and complete the timing belt replacement and water pump replacement. Simply click the blue links to receive an estimate for both services.

My car twice out of 4 times today would not start on the first time. Second time started fine. At 2 read lights it was sort of je
ANSWER : Hello, thank you for writing in. Your symptoms point towards an issue with fuel or spark. If you just had work done on the fuel system, you may wan to have your fuel pressure tested at the engine. This will let you know that the lines, filter, and pump are all working correctly. You should also have the ignition system tested. This would mean inspecting the spark plugs to make sure they are in good condition, and making sure the plugs are receiving spark. Testing for spark is best done with a simple spark tester that is inserted into the plug’s wire. If having trouble starting, turn the key to the "On" position before starting, and let it sit. This give the fuel pump a moment to prime. If you do not hear the faint buzzing of the fuel pump priming (you may have to listen closer to the fuel tank), then you may be having issues with the pump. Only further testing will tell. For more help with testing and repairs, contact our service department to schedule an appointment.

Car hesitates and slows down badly at times. It almost stalls at times. It keeps slow speed at 20-30KM.
ANSWER : Hello. I would need to know the year of the vehicle to know where the fuel filter is located. If this is an older model, it is located under the vehicle. Most of the newer models only have a filter on the fuel pump.

From what you are explaining, it sounds like the fuel pump is failing. When the fuel is low, the pump will get hot and a weak pump will lose pressure causing this to occur. I would usually check the fuel pressure to see if it is low, especially when the fuel level is low. If it is, then the pump needs to be replaced. If you plan on having this done, consider YourMechanic, as a certified technician can come to your home or office to diagnose the hesitation problem and guide you with repairs.

1992 Acura Legend, when the timing belt goes, is it common for the valves to bend?
ANSWER : If the timing belt break off, the engine’s pistons will hit the valves as the pistons are moving. The engine is an interference engine and can cause damage to the internals of the engine. The last time the belt came off, the engine may have been running at an idle or not under power. It is possible for the valves to be bent. What I recommend doing is performing a leak down test on the engine with a timing belt on the engine and properly timed to determine if the valves were in fact bent. If all of the cylinders have a 80 percent hold and not leaking, then the engine is fine. If there is a mass leak on a cylinder, then the piston did some internal damage. I recommend seeking out a professional, such as one from Your Mechanic, to help you check your engine’s valve train with a leak down tester.

When I went to change the timing belt there were 25 teeth were missing but it didn’t jump time – how is this possible?
ANSWER : Not all the teeth need to be present in order for the pulleys to turn. However, the only way to tell if the cam and crankshaft were really in the right position relative to one another is to line them up before taking the belt off and when the engine is at TDC on cylinder 1. If all the pulleys were lined up to the marks that are embossed on the engine, the only explanation is that the few remaining teeth were stout enough to turn the pulleys without breaking. However, even that doesn’t seem likely, especially since 25 missing teeth in a row would suggest that there weren’t even enough teeth for the belt to fully engage the crankshaft timing gear, thus slippage would have been inevitable. If the 2.0L engine you have has a double overhead cam, that is an interference engine (the single cam version of the 2.0L is a non-interference engine). If you’d like a professional technician check out the engine for damage, due to the failed belt, and/or install the new timing belt, consider YourMechanic.
