GRAND MOVE TIMING BELT TENSION

Forum: 

I posted this in the "poroblem" forum area a week or so ago, and have had no answers. Perhaps the problem forum area is invisible to all the people with the answer to my problem, so I thought I'd try the general area. The engine is a 1500cc HE-EG I think, and is fitted in another (more popular) vehicle, though I don't know which. Please can someone help me, as I worry more by the day about an engine blowup!

"My 1998 1500cc Grand Move, which I have had for a year, has done 70-odd thousand miles, and probably has the original timing belt. I cannot find a workshop manual for less than £100, and therefore am a bit stuck for info about the correct tension for the new belt, and any other relevant tips. I'd be very grateful if anyone can advise. Thanks, Dave Fisher."
