Question about 2005 Buick LeSabre
I am wanting a diagram of the evaporative emissions system on a 2005 Buick LeSabre. Check engine light came on pulled the code and was a minor leak.
Finding a leak in these emission systems is almost impossible.
All it takes is a pin hole in a hose to screw up the whole system.
The best way to find the leak is to take and have a smoke test done on it. Smoke is injected into the system and where ever the leak is , the smoke will leak out of it. It's faster and more reliable then replacing hoses and other things you don't need. Call dealers, or repair shops to see who does smoke tests.
