Q. I recently had to replace the engine in my Toyota Camry. It experienced 234,000 miles, and the new motor has about 150,000. I’ve seen that when it’s seriously chilly, the auto does not warm up when driving at freeway pace. When it is idling or heading slow, the engine warms up wonderful. What’s up?

A. Commence with a examine of the engine thermostat. If the motor was sitting down in a salvage property for a although, the thermostat may be opening at too very low a temperature. This would be most obvious at highway speeds. If the thermostat is all right, then the trouble could be air in the cooling system. This could be a outcome of a defective head gasket, which is why the automobile could have been in the junkyard.

Q. I like my 1998 Volvo and strategy to generate it as very long as it will go. It has 223,000 miles on it. Volvo components are really expensive, so I have been shopping for components on the net. I’d like to fully grasp aftermarket components. Are there several qualities? Really should I be asking for a certain producer, offered that I program on preserving this motor vehicle as extensive as I can?

A. I have no problem with aftermarket components. That claimed, many substitution parts are equivalent to and in some situations could surpass the primary equipment pieces. Appear for identify brands from reputable areas stores these kinds of as NAPA. I have also had great luck with on line parts stores these as Rock Automobile and CariD. When I’m browsing on line, I tend to seem for brand name names that I am acquainted with that will give great company. As a normal rule, if the substitute element is substantially much less expensive than the unique machines part, the top quality may perhaps be questionable.

Q. I lately bought a 2013 Nissan Pathfinder with 27,000 miles. I hear a knock from the engine that is relatively apparent until finally the car warms up for a moment or two. I took the car to Nissan and had somebody push and check it. They advised me there are no issues codes and the knocking sounds is normal. Does my truck have a issue?

A. It’s not strange to hear a slight knocking noise when the engine is chilly. There is so considerably aluminum in engines nowadays that elements will expand and deal as they warm up. As extensive as the sounds goes away speedily I would agree with the seller and simply call it normal.

Q. I have a 1999 Honda Accord and the service-motor gentle came on. The repair store explained to me it was the evap system, but they couldn’t come across nearly anything improper. They said the challenge was not on the gasoline aspect. They reset the personal computer and all was properly for almost a few months. Then the light arrived back again on. What just is the evap method and must I be anxious about the light-weight?

A. The evap method is the term made use of for the evaporative emission manage method, which helps prevent gasoline fumes from escaping into the atmosphere and creating extra pollution. Considering the fact that 1996 most autos have had an onboard test of this system to be certain it doesn’t leak. Whilst in this scenario, the car’s performance will not adjust when the “check engine” light is illuminated, your car or truck is causing air air pollution. The most common trigger of an evaporative failure is a loose or faulty fuel cap.

Q. I listened to somewhere that if several people today share a automobile, it will have on out more quickly. We have three automobiles in the household. I think each individual individual should really generate their individual vehicle. The other two motorists really feel they can soar into what ever is previous in the driveway. Who is right?

A. This arrives from an old adage and may be correct – but to a position. When extra people today travel a automobile, no a person requires responsibility for the preventive maintenance and small repairs. Every person thinks the other individual took care of the oil adjustments, checking the tires, and other critical difficulties. There is no explanation a car pushed by numerous drivers really should have a shorter existence as long as anyone requires responsibility for maintenance and repairs.
