The coolant in the reservoir looks fine no discoloration or anything.
I'm 90% sure that I saw a coolant change was done at some point on the Carfax or something which is why I didn't do it when I changed the differential/transmission fluid.
I've got a new to me 4runner at about 185k miles. I've done most other things but held off on coolant. I'm wondering if i should just do a drain an fill from the radiator/engine or do a flush.
What a crazy thread resurrect though.
Since I can't post new threads yet, I'm going to revive this thread. Is this the rattle/squeak that you guys were hearing:
