The 1994 940 Turbo that recently came to grace our garage needs a new thermostat and a coolant flush. I am considering doing all the hoses and water pump as long as I am already dealing with the mess of flushing the coolant. Timing belt was done 30k ago so I am leaving that put. The heater hoses look like quite a chore to change, but they probably are 10 years old.

I am seeing five hoses I need to change:
Expansion tank hose
Upper radiator hose
Lower radiator hose
Heater intake hose
Heater output hose

Plus an 87c thermostat, water pump, an expansion tank, a black cap, and some clamps. And of course the Volvo blue coolant. Looks like about 300 bucks. Ouch. And that's with a gmb water pump, wahler stat, and mackay for three of the hoses (other two are volvo).

Anything I am missing here? I was planning on just a scour brush and warm water for cleaning, no sealant or rtv.

Also, all the expansion tanks available look much different than the round one on my 940. Is there a different mounting mechanism for the square ones?

Thanks much. This looks to be a major chore (and not cheap), but my old 740 blew a heater hose in the middle of an ice storm in nowhere Pennsyltucky late one night many years ago and I'm still nervous about hoses. I read the FAQ on the heater hose change. Looks like I should save some money for drinks after.
