EGR valve needs to be replaced how do I replace it or how can I clean it out?
Well if your going thru the trouble to remove it. It's a real toss up I know the part is expensive. If all it needs is to be cleaned then clean it, if it doesn't hold vacuum or open when it's needed then replace it. As far as the actual proceedure, the egr is always located in an nearly inaccessible location on the engine. So you get frustrated and take it to a mechanic and he gets frustrated but then he's getting paid. It has 2 or 3 bolts and a vacuum line, either metal line or vacuum hose. After removal if it's clogged it will look black inside gummy sticky clean it with carb cleaner, don't spray it soak it to remove the mess it's not very big inside, it has a plunger, a rod and a small chamber, after cleaning apply vacuum to it to make sure the plunger opens and closes ( it will move) There is no lube for this part exhaust gases pass thru it hence the name Exhaust Gas Recirculation, Hope it helps
