Is fan working properly
I am thinking you need a water pump but just need to qask you a couple of questions.
Also when replacing the thermastate you will want to test it as they have been known to be bad even though new.
you would just boil water to get it to open at 190 it should open. Make sure you get all the bubbles and air out after replacement
if the is air between the thermastate and coolant it will have to over heat to open.
yes, fan wasn't working properly when I first got it but now after I replaced fan relay now the fans due kick on. One thing that I did notice is that the bottom hose where the thermostat is located wasn't getting hot at all. Also, I didn't get any any surge when I squeezed the bottom hose. The top radiator hose was getting hot.
how do you bleed this system?
You would want to run with cap off until bubbles are gone if temp gets to 3/4 hot turn off and let cool down when it cools down it will bleed some of the air
Then when it cools down start it again til you dont see bulbbles. or it hits 3/4 again then turn it off again.
it a pain I know.
I tried to let it run with cap off the resevoir since on this particular model the reservoir is actually pressurized. but it didn't seem to me that it was circulating.
is there any definitive way to know if water pump is circulating?
if all the bubbles are out it may be the water pump then. the hose under thermastate not getting hot could be air or a water pump
If its not circulating the water pump may be out.
with the cap off the reservior should you see movement in the reservoir tank? Or if you squeezed the bottom hose should you see any change in the level in the reservoir?
yes if you squeez hose it should push coolant
so if it doesn't would it definitely be water pump?

The water pump doesnt have to leak to be bad if blade breaks off
You dont want to damage the housing. The clamps pinch off or cut off if you will. The hose and clamp is one assembly. So you will have to replace the whole hose and clamp. Of course its a dealer tool and part. This is something when you get it back on you will have to have a hose clamp tool to crimp back on. With as complex as this could get you would want to have dealer do it with thier tools. Or at least show you hands on til your confident. If you have any other questions please let me know.
