Does a thermostat on a 1999 chevy malibu twist in

It is much easier, and cheaper to find a steering knuckle or "hub assembly" in a salvage yard.
To begin, jack up the car and remove the wheel. Be certain the car is stable and will not roll off jack(s)!
Remove the spindle nut. Remove the brake caliper (hang on a wire). Remove the bolt for lower ball join. Remove the bolt that goes thru strut. Now, pull assembly off while prying to ease pressure from the lower control arm.
Depending on how many miles you have on the car, you might want to head-off some future trouble by replacing the half-axle while you have the front end disassembled.

That engine does not have a timing belt, it has a timing chain and therefore much easier to work with as it can only go on a certain way, the primary focus being getting the dots on the timing chain sprockets lined up properly.

I believe, with the engine at Top Dead Center on cylinder #1, the dots will be facing each other. That is to say, the do on the cam sprocket will be facing the dot on the crank sprocket.

Before starting this job I would get a repair manual. This is not a easy job, 6+ hours for an experienced tech with all of the right tools. And you may have to discharge and recharge the AC system.

Thanks Pierre!

Merci beaucoup!

Everything worked as mentionned. Be carefull with the plastic in the winter. Make sure to use a flat screw driver and get it close to the slider and not on the edge. I cracked one of the tongues. Those L shaped slots are under the plastic cover with the two big plastic plugs that you also remove with the flat screw driver
