We need to replace our radiator hoses and the parts guy asked if we had an advanced evaporative control system because it made a difference in which lower hose. I read about what they are but have no idea if a Land Rover Discovery LE has one. Do anyone know? Thanks

 

They all have them. I believe yours is the Advanced EVAP


How To Identify Emissions System On Discovery 1

 

Have the parts guy cross reference PCH000070 (they can leave off the "G" at the end), that's the lower hose for a '98.
How To Identify The Evaporative Emissions Family Of Your Discovery 1

 

X2, 1998 D1s have advanced evaporative loss, aka AEL.

 

The "G" only means genuine. Yes your truck is AEL.

 

AEL was introduced mid 1997. What I always tell my customers is take a look at the charcoal cannister. If it's round, you have the earlier style. If it's rectangular, you have AEL. It's the easiest way to make the determination.
