The fuel economy has decreased slightly after having the cam-belt replaced. Don't know why.
This is the Liteace Noah Fieldtourer van/people mover sold in Japan and imported as second hand.
I brought the van as a part people mover and part camper as I took out the rear seat and installed a shelf that forms a bed, big enough for my boys to sleep in when camping. It performs both tasks fantastically. Also tows the trailer with quad bike without any problems. The van is tall and narrow but this dose not alter it's almost car like driveability and being up high is a plus in traffic. The responsive two litre engine and auto makes driving in traffic stress free and highway driving is without any problems, passing at 100kph being quick and simple.
I had the cam-belt replaced recently and while the power is still there, the fuel economy has dropped from 11.4 km's per litre (27mpg) to 10.6 km's per litre (25mpg). Even this is better than others in it's class so I'm not complaining to much.
All in all, I find it difficult to fault this van and recommend it to anybody who needs to move 6 to 8 people without being to 'agricultural'.
The timing belt has 'teeth' around it, and maybe when the new belt was installed, the teeth weren't lined up correctly with the cogs it runs around. If I were you, I'd get the timing checked out; this could be slightly out if the belt wasn't installed correctly.
I had a diagnostic check and it showed OK, with no error codes, although I must admit, there is a faint detonation sound under some load conditions. I'll try a timing light.
