Tacking this job right now and I'm just wondering if removing the expansion tank is necessary. Reason why I'm asking is that the shop that replaced the timing belt last time never put the bolt back into the support bracket (see pic). It's been over 4 years and I've had no issues without the missing bracket bolt it seems. (Is the bracket even necessary?) I'm assuming you have to move the coolant expansion tank to get to that bracket bolt, but in my case it may not be necessary. So if I remove the two bolts from the top motor mount, I should be able just slide it out, no? Just wondering if anyone else has done this without messing with the expansion tank.
