Correspondingly, what are the symptoms of a faulty EGR valve?
EGR valve symptoms can vary, however, the most common symptoms of a faulty EGR valve are explored below:
- Your engine has a rough idle.
- Your car has poor performance.
- You have increased fuel consumption.
- Your car frequently stalls when idling.
- You can smell fuel.
- Your engine management light stays on.
Secondly, what causes EGR cooler failure? A restricted oil cooler will cause reduced coolant flow to the EGR cooler, causing it to melt down. Any type of coolant (be it headgaskets or any other type of leak)leak that causes air to get trapped in the EGR cooler will cause it to melt down. Excessive EGTs will cause it to melt down.
Herein, can coolant leak from EGR valve?
When the EGR cooler leaks, the core allows coolant to enter the intake manifold. A large leak generally will cause back-pressure to enter the radiator and cooling system causing the engine to overheat as well as the engine oil.
Can you drive with bad EGR valve?
A stuck EGR valve can cause the engine to ping, and that will soon destroy it. Based on the performance issues you described, it sounds like the EGR valve pintle occationally sticks in the open position. EGR typically should only takes place at low load, highway speed driving conditions.
