My car starting smoking and coolant leaked. Took it to mechanic and had hoses replaced and radiator installed.

Same problem happened again and now car seems to idle real rough? Any ideas what I should check first.

 

Do you mean the hoses broke again?? Or the radiator??

Is the engine overheating?
Check the temperature gauge?
If so then is the thermostat stuck closed??
If so then is the water pump working??
If so then is the cooling fan turning on??

 

I went ahead and power washed the engine because it was very dirty. The car doesn't seem to be leaking fluid anymore but is still getting hot after running for 10 to 20 minutes. It has a new radiator, new upper and lower hoses, new thermostat with new seal o ring seal and housing seal.

Still overheating..... How can the water pump be tested without removing?
Anything else I should check?

 

fans seem to be work fine as well.

 

If you have got new thermostat, radiator and hoses, it isn't leaking and the fans are working ..
Then what could it be??

My thoughts are water pump, blockage somewhere, or very low coolant level
When checking the water pump, start with a cold engine and remove radiator cap.
Run engine and when engine reaches normal operating temperature,
You should have an open thermostat (allowing for coolant flow)
And then look inside the radiator for coolant movement.
No movement then water pump is suspect.

 

Thanks - I'll try that when I get home today.

How hard is it to replace the water pump on these 2005 Hyundai 350 Xg. I heard you need to remove timing belt cover.

I wonder how difficult it would be and how long and how many steps to do it right?

 

Take a look on youtube for changing any water pump
That will give you an idea of the degree of difficulty

Some say it is easy
Others won't attempt such things

 

Thanks. I ran that test you suggested and it failed .The coolant does not seem to be flowing at all.

Now begins the difficult task of removing water pump. From what I gathered , this will be a real pain in the butt. Just getting to the lower half of that timing belt cover is a nightmare. Arrghhhhhh

 

So, you ran the engine until the cooling fans turned on?
And you checked the coolant flow?
Also, waited a little while to make sure thermostat opened up?

Personally, I would hate to have to change the water pump myself.
So, got to be absolutely sure before I would attempt it
There are so may bolts that can get lost or put in the wrong place.
This one guy changed his brakes and ended using the wrong bolt and it was too long and locked up his brakes.
After I suggested to go over again what he did to change the brakes, he found out this mistake.

Good luck

 

Thanks. Brakes are easy. I wish the water pump was that easy So many layers to peel off before I can actually get to the pump. I ve been searching all day for some engine diagram, schematic, or good video to make it go a little easier but have not much luck with this specific engine. I guess I'll just have to go extra slow and take pictures as I go along.
