2003 Nissan Altima Questions
I was having problems with my timing chain over a year ago. Instead of replacing the chain, my mechanic just replaced the guide. Within a year, the chain jumped off and it messed my entire engine up. My mechanic suggested replacing the engine (put one in with 61000). It was a spendy fix, but ...

If I pull over and shut the car off for a minute it starts right up and drives fine for a couple of more days. What do you think t...
2003 Nissan Altima Recalls
The engine coolant temperature can vary at the coolant sensor due to its unique location. If these variations are large enough, a brief interruption in the signal output from the sensor may occur. If the signal interruption is so brief that the electronic control module (ECM) logic does not have time to diagnose the condition, the engine may stop running without warning. This condition will commonly occur only at low speeds. If the engine stalls without warning, a crash may result. Dealers will reprogram the ECM to correct this concern. The Nissan recall number is R0606.
Nissan is recalling 2002-2003 Altimas in cold-weather states because in extremely cold temperatures, moisture in the fuel tank could freeze and form ice crystals, which may obstruct the suction opening of the fuel pump. This can prevent the supply of fuel to the engine and cause the engine to stop, which could result in a crash. Dealers will install a screen at the suction opening of the fuel pump.

2003 Altima 3.5L SE V6 - catalytic converter went out at about 100K and got sucked up into engine resulting in later engine failure. Cost $7K to replace engine. This is common with the 2.5 4-banger so what happened to me? Also, before engine began to fail I had a rattling noise in the engine which turned out to be the timing belt tensioner. I wasted $2K getting this repaired on what later becam...
