Problems Under the Bonnett

[Maltrice]

Well due to my bad power steering pump it locked up my water pump which in turn fried the thermostat. Well I ordered a new pump last week before this happened and when I had to park it due to the water pump failure I decided to pull the valve cover to refinish it and throw a new gasket on it, well after I got it refinished it and put it back on I fired it up for a sec to check for leaks. I have a little gap all the way around the cover but no leaks. Also my ide is higher, It use to idle at about 600, it now idles around 1,000. I'm heading out now to change everything else but is the change in idle normal?

is the idle in park or drive? is it during cold only or all the time? did you check to make sure you reconnected all the hoses you removed (i.e. the ones hooking up to the intake pipe) & accidently removed (i.e. possibly a few vacuum lines behind the valve cover).

so you're power steering pump bearing froze, which made it impossible to move the belt which in turn stopped your water pump from spinning and pushing water through the engine... I follow that part.

How exactly to you fry a thermostat?

Did you overheat the motor? Did you warp the head? Do you have a blown headgasket now?

Ono is most likely correct, you missed a hose coming off the intake piping somewhere and that is throwing off your idle speed.

You have to install valve cover bolts one by one in a certain order. That's why you have a gap. Search NICO, you will find the diagram from FSM.

Disconnect the battery, reconnect and see.

If car runs fine, I'd lower the RPM and see what happens. It's also in FSM and easy to adjust. You need to unplug throattle position sensor before you start the car, adjust the idle and reconnect. Everything's in FSM.

It's weird to see someone says 'Bonnet.' Japaneses and Europeans use that word.

I didn't run it that hot, but it ran hot enough to rupture the lower hose and send the spring on the thermostat out with it, no water in the oil. no gaps on the block where the head connects. All the hoses where connected, i figure that it was originally a compression leak because before I changed the gasket there was oil on number one and two plugs and half way up the plug wire. the original gasket was also missing parts on the inner gasket, the one around the plugs. I thought it was idling a little low when i got the car so whats the normal idle of the KA? I'm fighting the banjo bolts on the old pump trying to get them off, thats a whole different monster. I had to walk up to O'rielys to get new orings for the hoses. Its a real mess under there. I figured with it being a 16 yr old car things would start to break down but not this bad. If you have anymore questions about whats going on I'll be checking the forums all night.

It's good for reference - assuming you are automatic (vert forum).

[Maltrice]

Its the same in both, doesn't change. I forgot to put that in sorry

1000rpm in Park is normal. 1000rpm in Drive is not. you should be somewhere around 650-800rpm in Drive.

Like 94_240sx said, if it runs fine other than the high idle, consult the FSM on how to lower idle.

ok...wtf...I loosed the hose that comes from the ps resevrior, I took apart the tensioner assembley, and took out the bolt behined the pulley on the ps pump. but the damn thing still wont come out! I also have no clue how I am going to take off/ and tighten the banjo bolt since I dont have a socket that big. anyone got any tips?

[onosqv]

What are you trying to do? Loosening the hose from the ps reservoir shouldn't have anything to do w/ the problems you mentioned in the original post...

You do need a socket and a breaker bar to loosen it. Yeah, I wonder what you are trying to do here.

[Maltrice]

I was able to brake it loose. what i was talking about was the banjo bolt holding the power steering line to the pump itself. the big line that goes down to the steering rack. I ended up having to by a whole new pump because the one I recieved was for a frontier...once i get pictures of everything maybe that wil help explain.

ok...new power steering pump installednew thermostatnew water pumpnew top and bottom radiator hosesflushed all of cooling systembled both systems. new problemcar is still overheating. badly. there is a new symptom. as long as I have the bleeder bolt out and the radiator cap off the car runs right. as soon as I close the system it begins to overheat. any clues guys?

Jack up the front of the car as high as you can and bleed. Don't do it on flat suface.
