It would help if you said what the problem is. - Thermostats usually either work or don't. If they don't it takes a long time for the engine to get warm, -this has nothing to do with the water pump.
Water pumps sometimes leak, you lose water and can see this in the rad. -there is no repair, -you change it for a new one. -This problem has no similarity to any thermostat problems.
cracked head. or call a repair shop. theyll tell you
check the casting plugs they could be rusted out if your car is old
it's an alone pulley mostly found bulted to engine block. the belt can run under or over it
Engine size is often measured in CC's (cubic centimeters). I believe some engines (in USA) are measured in CI's (cubic inches). Perhaps Harley Davidson motorcycles. . . Volume

If you insert the oil in the tank, where power steering fluid should be, then yes, it´s harmful.
Sometimes lightly tapping on the bolt with a hammer can cause some of the material that binds the bolt to break loose. Don't get too energetic though, you can cause damage. Next step, apply a little heat to the nut or whatever the bolt is attached to. Try to keep the bolt a little cooler than the nut so that the nut will expand slightly more than the bolt.
There are conical remover bits that you screw counter clockwise into a hole drilled in the center of the bolt that will loosen many problem bolts. You will need to replace the bolt if you are to put your machine back together.
After that, get a grinder or hacksaw and plan to replace the bolt.
ANS 2 - Many bolts like this will come loose with an air impact wrench. Try this with a proper impact socket.
ANS 2 -If this pulley is not moving, the crankshaft is not turning.
Change it every 60,000 miles. This is an interference engine and as such if the belt breaks serious engine damage will occur. I also recommend you change the water pump which is driven by the cam belt if you are over the 100,000 mile mark and you have never changed it. This will save you money on labor costs later on.
Depends where it's leaking, but basically you fix it the same way you fix any coolant leak.

Generally, its a hose that is leaking. You find the leaking hose, and you replace it, being sure to properly treat the ends with anti-leak compound. If its the radiator, you need to replace that. If its the intake manifold or head, you are getting into big bucks to replace the gasket involved.
Belts have to make at least a 180° wrap around engine components. To do that, they sometimes have to place an "idler roller" under the component before they can route the belt to the next component. That idler roller doesn't power anything. It just keeps the belts wrapped properly around the preceding pulley. The roller has a bearing in it and sometimes that bearing wears out.

Actually , someone is joking with you because there is no such thing as blinker
fluid
That is very likely a slightly loose serpentine or other drive belt. In colder weather belts get stiffer and slicker, fluid (as in the steering pump) gets thicker and harder to turn . If it diminishes when your car warms up, that is almost certainly the cause. - Let a mechanic hear it and diagnose it. There is also the possibility it could be a bearing worn in alternator or any other belt driven part.

The engine cover is probly not tightened down. It has to be removed to get to the oil filter on that car so probly an improper re-installation.
