I have a 1992 Volvo 740 NON TURBO wagon. It has 210,000 miles on it an
I keep it in great shape. The timing belt was last changed about twent
thousand miles ago.

However today the timing belt broke as my wife was going about thirt
miles an hour. Everything just stopped and she was left at a dead sto
in the middle of an intersection.

Before I listen to what the mechanic has to say I'd like to know if m
1992 Volvo 740 non turbo wagon has a *non interference* engine. It's m
understanding that if it *-does-* no damage has been done to th
engine.

I'd read on the internet that 1992 was the last year Volvo made no
interference engines. I'm hoping beyond hope that's accurate.

Any help would be greatly appreciated.

Thanks

However today the timing belt broke as my wife was going about thirty
miles an hour. Everything just stopped and she was left at a dead stop

It depends on what engine is in it. The 8 valve engine is
non-interference, though the clearance is much tighter than the turbo
motor and there is some chance of contact if there is a lot of carbon
buildup. The 16 valve engine is interference and major damage is nearly
certain. IIRC both were available that year.

I'll defer to Mr. Sweet to correct me but I think you have it backwards
in that it may have been the last year for the "interference" engine
(B234F).

Thanks to all this group for the always helpful information,

The B21, B23, and B230 are non-interference. The B234 is interference,
as are the "whiteblock" engines used in the later cars. A good rule of
thumb is that if it has more than one camshaft, it's an interference engine.

20,000, I would look into the mechanics and belt manufacturers
warranty, something aint right to go at 20,000.

It's diffrent between 2.0 B200F or 2.3 B230F, B230F is non interference, but
smaller B200F is interference.
 
I would worry why the belt broke after such a short life .If you haven't got
16 valves your ok .But question why the belt broke in 20 thousand miles .

I would check the tensioner for wear and damage, as well as the
sprockets, and make sure everything was put together right. Could have
been a defective belt, but I haven't yet run into one.
