888dee, as others said its possible to lower the engine to do this.
If you snapped a belt, you most probably have at least 2 valves bended on one side.
You need to:
remove brake hoses
drain oil and water from the engine
disconnect clutch hose
disconnect power steering hoses and a/c if you got one
disconnect fuel hoses and radiator hoses
remove exhaust manifolds
remove lower side engine mount
jack up the engine and undo the top engine mount as well
then lower the engine.
if you just remove the drive shafts and rear gearbox mount, then disconnect the electrics - which is probably another 15 to 20 mins job, you will be better off !
If you do this job with the engine hanging in the engine bay, you need to know about these issues:
Because the car will be on jacks, you will either need to be on your toes and bended in the engine bay to do any work, or flat on your back with spiders crawling into your ears !
Frustration and anger come easily in these positions
Access will be hard, and the efford/strength needed to undo bolts and remove the heads, will shake both the engine and the car which will be on the stands, with the risk of dropping the car on the ground - hopefully without yourself under it
By removing the engine completely, you will have much better access, much safer enviroment, and you will also be able to fix or replace other parts that might show up as well
My advice ?
Take that engine OUT
