1) I want to replace the thermostat so what's the recommended way to drain the coolant prior? Not going to flush by the way
2) Would you recommend a certain coolant?

There's a drain on the radiator, and two block drains, usually draining the radiator with the pressure cap removed will get you there

Didn't realize there were two block drains. But are you suggesting that just draining the radiator should suffice?
If you leave the radiator cap on, it'll suck the coolant out of the overflow tank as it drains. (Assuming that this vehicle has a radiator cap and an overflow tank).
I discovered recently, the hard way of course, that if the thermostat regulates coolant flow in the lower rad hose (rather than the top one, as is more common), draining the rad does not drain the engine block. (This involved installing a block heater in a 2003 Acura TL 3.2.)
Be aware, and have extra coolant on hand.
Had I also used a block drain, as @michaelluscher has pointed out above, I wouldn't have created a great deluge on my driveway.

Would do you guys think of this antifreeze?

Drain from the drain cock in the radiator. Refill using the Lisle coolant funnel. Only use an OEM thermostat.
For those who don't know, the 1MZ doesn't have the radiator cap directly on the radiator itself. Instead, it's connected to a hose, and the cap is in the middle of the engine.

I bought this 180 degree Murray stat
I would have went with an OEM T-stat
Given "Murray" doesn't actually make the part, there's a good chance that there's either a Stant or a Motorad unit inside the box. Either should work just fine and are of good quality, the Motorad getting a slight nod.
Nope, don't use Murray Stat or Stant Stat.
You need OE Toyota stat, IIRC, Kuzeh brand but you can go to stealership to buy it.
They are not too much more than the aftermarket.
The aftermarket stat never behave properly.
Buy the OEM thermostat from the dealer only, unless you can find a reputable site online
Another good choice is the Aisin THT-019, but again, only buy from a reputable seller.
I wouldn't mess with the block drains on a 27 year old car that probably has never had it loosened before. Snap it off and you have big problems. On the other hand, I just loosened the drain on my 86 Volvo.
Surprised the censors didn't cock block you. It's called a drain valve in polite company.
Unbranded no-name? I would avoid. If you already bought the Murry and don't want to get Toyota, not a big deal if it's not hard to replace.
agreed
I'm surprised too
I had actually forgotten the word petcock when I posted the earlier reply
Motorad bought out stant. They seem to have completely killed off the stant line.
You may not find the block drains easy to get out. If they are hex then use a 6-pt socket.
I would drain the radiator and then pull the thermostat. If you loose some coolant just rinse with a garden hose.

I had noticed I was having a harder time than usual finding a stant super stat a while back... That's really unfortunate news at least to me. Every Motorad tstat I've ever tried has been garbage.. Had good luck with OEM and Stant
