You need to check to make sure the cooling fan is coming on. If it is not then further diagnosis will need to be done by scanning the computer to see if fan control is turning on to see if...
Hi Marvin. Thanks for contacting us today. The main cause of over-torquing is using an impact or air wrench. However, the majority of damage occurs when the torqued component is in use, develops heat then cools. In your situation, catching...
Hi Philippe. Thanks for the question today and writing back. If you'd like to request an estimate to have one of our mobile mechanics come to your location and diagnose the root source of this hard starting issue, click this...
Depending on if you overheated the engine and it still has the cracked radiator, then you may have more than one problem. You may have a problem with the crankshaft sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-crankshaft-position-sensor) if you are not getting spark. You said...
Hi there. Check the fuel injectors and see if they are working or not. If the fuel injectors are not working, then you would need to replace the fuel injectors. If the fuel injectors are fine and the engine operates...
If you have spark and you have fuel pressure then the only thing left to test is the fuel injectors (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fuel-injector). You will need to have a fuel injector noid light to connect to the injector connectors to see if...
If your coolant is low, you may have a leak that needs repaired. If your coolant level is normal, the problem may be with your thermostat (this part regulates engine temp), the cooling fan, or radiator. You need to have...
Hello. A ticking sound from the engine can be caused by a few different things. Two of the most common causes, as you already figured, are from faulty injectors or an issue with the valve train. If the clicking is...
Hello, thank you for writing in. Unfortunately this is one of the situations where the possible causes can be with a lot of different components. You may want to do some further testing on the intake air temperature sensor. There...
Hi There, It sounds like you may have a dirty or failing idle air control valve causing your engine idle to fluctuate and eventually stall. The idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) is a small valve on the engine's intake system...
Hi Dorian. Thanks for contacting us today. The mass air flow sensor itself is an on or off type of component, meaning it either works or it won't. It doesn't take time for the sensor to 'break in'. The issue...
High idle should be corrected as it will cause harsh transmission engagement, waste fuel, and make it difficult to stop the car as the engine surges ahead. High idle can be caused by a faulty idle air control valve (IAC...
Hi Jervon. Thanks for contacting us tonight. While installing spark plug wires incorrectly can cause misfiring, it's quite possible that you had an existing vacuum leak. It's also possible that the vacuum leak may have been caused while you removed...
Hi. The parking brake system on the Maxima uses 3 cables. One control cable from the handle, and one cable going to each rear wheel brake caliper. A visible inspection of both calipers needs to be administered with both the...
Water in the oil usually mean you have a blown head gasket. (https://www.yourmechanic.com/services/oil-pump-cover-gasket-replacement) This happens normally when the engine overheats and warps the head causing the water to leak into the oil passages of the head where the gasket meets...
Hello. If this only occurs when the engine is cold then you may have a sensor reading incorrectly or you may have a vacuum leak. Most of the time if the Check Engine Light (https://www.yourmechanic.com/services/check-engine-light-is-on-inspection) is on I start by...
Engine stalls are often caused by a malfunctioning sensor if not lack of fueling or ignition system maintenance. A trained technician will take them all into consideration. Worn spark plugs may cause a stall on their last leg and prove...
A stuck closed thermostat will cause a reduction of coolant getting into the radiator so heat can be transferred out of the cooling system. The thermostat will need to be replaced (https://www.yourmechanic.com/services/thermostat-replacement) if it is indeed stuck closed and the...
The taillights are controlled with a relay in the left kick panel through a couple of different fuses; the taillight fuse could have been blown from a trailer hook up. Check the fuses first to see if one got blown....
Hello. I would first try to determine if the sound you are hearing is engine or suspension related. If the sound seems to come and go according to your engine speed, then the sound is likely engine-related. I would put...
