Yes, you have to remove the camshaft from the engine to replace the timing gear.
The timing gear is pressed both on and off of the camshaft using an arbor or other suitable press.
Since there is not room to remove the camshaft in the car the engine has to be out of the car.
no The Chevy Celebrity 4 cylinder engine doesn't use a timing belt, it uses a timing gear. To replace the gear it is necessary to remove the camshaft from the engine as it is a press job. To remove the camshaft it is necessary to remove the engine from the car.
remove the valve cover,remove timing belt , lossing all caps that hold camshaft,then remove the caps, lift out the shaft.
The Maintenance Schedule requires Inspection (and replacement if necessary) of the Camshaft Drive Belt (aka Timing Belt) at every 30,000 miles and Replacement at 105,000 miles.

No. Timing belt replacement is possible in vehicle.
You can set the camshaft timing on your automobile by lining up the timing marks. There will be timing marks on the front main pulley and timing marks on the camshaft.
The thermostat housing is behind the camshaft sprocket. Remove timing covers and belt then remove camshaft sprocket and then rear timing cover. .
You have to remove the timing belt cover,camshaft pulley and timing belt.Itis near the top behind the belt.
