Camshaft Pulley Holder

I will be doing a time belt job pretty soon using AISIN timing belt kits from Rockauto.

I am looking to get a Camshaft Pulley Holder to lock the front and rear camshaft from moving while removing/installing the timing belt. Do you know which one will work on the TL?

Pretty sure a commercial kit dedicated to the J-series engine does not exist.
Besides, I thought you were all about a 'low tech, low cost' mechanical approach, like what's displayed below?

why bother, just take it off and then move the camshafts back to TDC before putting the new belt on

ok. How far does the camshaft jump forward/backward if it does not stay put after everything is TDC. Not much to worry about valves hitting?

In my experience, they should not 'move' at all, once carefully placed at TDC, if you take 10 minutes to first remove the spark plugs.

The valves will only contact something if forcefully OPENING when they shouldn't be (i.e. not timed correctly)
The valve springs help to close the valves. If the camshaft spins immediately when the timing belt is removed from the cam gear, this is CLOSING the valves. AKA nothing to worry about
If you do need to rotate the cams back to their original TDC position for whatever reason, just go nice. and. slow. Just remember that you will be fighting against the valve springs, so it will spring back on you if you're not careful. And if you meet any mechanical hard stop, stop immediately. This means something isn't timed correctly.

Just read the FSM. It goes over every single step, in detail.

Sorry for the confusion, I was mixing my 2 cars up; This past weekend I put the timing belt on the STi, where 2 of the 4 cam's do need to be forcefully spun with a 1/2" breaker bar back to TDC in order to install the timing belt. The other 2 can be spun by hand.

Yesterday I resealed the oil pan and pump on the TL (aka needed to remove the timing belt) and I can tell you rest assured that once everything is @ TDC, all valves are fully closed and the cams will not spin once the belt is removed.

Thank you for the confirmation! I watched a few YouTube videos and some of them tell you to remove the front bottom plastic guard in order to open the drain plug to drain the coolant from the radiator. It seems a lot of work to remove that plastic. I am thinking just let all the coolant gushing out at the water pump when it removes.

Question.
is it ok to run the engine for 1-2 minutes (after installing a new timing belt) without the serpentine belt (or without crankshaft pulley) , timing covers and the power steering pump installed?

I want to make sure no strange noise or coolant leak before assemble everything back.

Without the serpentine belt? Absolutely.

Without the crank pulley? Absolutely NOT! That's holding the timing sprocket and woodruff key onto the crank snout, and if 1 of them were to slide off......

Done and success!
The most time consuming is removing the serpentine belt tensioner and the timing belt covers and torqued back the crank bolts
