Troubleshooting and repair of QG15DE engine
QG15DEThe Nissan QG15DE engine was developed from the 1.6 liter QG16DE and was designed to replace the GA15DE. In the QG16DE cylinder block, the cylinder bore was reduced from 76 mm to 73.6 mm. Accordingly, other pistons were used, and the compression ratio was increased to 9.9. Otherwise, it is the same QG16DE. To reduce the toxicity of the exhaust, EGR system is applied here, and mechanical throttle is also used.
Since 2002, after some updating, the motors received a CVTC intake timing system, electronic throttle and the EGR valve was removed.
QG15DE motors were equipped with a timing chain, replacement is carried out approximately every 150 thousand kilometers, sometimes earlier.
QG15DE was not equipped with hydrocompensators, so every 40-50 thousand km it is necessary to adjust the valves.
The motor was produced not too long and for some time, QG15DE was removed from under the hoods of Nissan cars, and its place was taken by a newer HR15DE.
Nissan QG15DE engine problems and shortcomings
The QG16 and QG18 motors are similar in design to the QG15, so their problems are the same: won’t start, high fuel consumption, noise, whistling and more. Details can be found here.
Nissan QG15DE engine tuning
Chip tuning
The best thing to do is to buy a QG18DE engine and swap it. Tuning a 1.5 liter veggie motor is not the best idea. However, if there is nothing to do, you can buy a 4-2-1 exhaust system and do chip tuning. This will give about 10 hp and an aggressive sound, the rest is unnecessary.
