I don't want to sell my vert...

[Maltrice]

But its making it very difficult. The timing issues are driving me nuts, I've replaced the water pump and thermostat and have bled the system until i thought i was going to bleed but it still overheats. there is coolant all over the top of the radiator but i cant find a leak when its running...

I want to keep my car, but in the last 3 weeks I have had to drop 700 bucks in frivilous little parts to keep it going and then it still doesnt run like it should. No mechanic will even touch my car and the dealership here in town refuses to touch it in fear they might have to replace something that isnt made anymore...Im frustrated to the point of almost wuiting, will someone please HELP me...

[biggie]

Apparently not bleeding 'properly' (like if you are only using the bleeder screw).

And pretty sure a Nissan dealership can't refuse to work on a Nissan. Also a dealership can use the vaccum system to make sure there is no air bubble in the coolant system.

[Maltrice]

the service manager at bill hood told me if I wanted him to work on my car I'd have to by a new one...and the when i went to the dealership manager he said nothing but tried to get me into a new 350...

To me, you have gunked up radiator. Make sure to touch upper and lower hoses and both get hot when thermostat is open. Jack up your front high up or drive up on 2x4 to bleed it. Worst case, some lube place has vacuum system that biggie is referring to, so try it. I think they charge $50 including coolant. Someone I know had a similar problem and he fixed it by replacing the radiator. It's possible you have bad readiator, so keep in mind.

I think they try to get rid of 350 since 370 came out.

damn i was gonna say try the water pump but looks ilke u've replaced it :S

try getting a new radiator cap

[cmkelly]

How much would it cost to replace radiator, cap, major hoses, etc.? Surely less than $500. Unless it's the head gasket that should resolve the overheating problems especially if you've replaced the water pump already. I'd hate for you to sell if if you're so close to getting it resolved.

[Maltrice]

from my local auto parts store, 208 bucks for the radiator. 36 bucks a pop for the hoses, and 12 bucks for the radiator cap. Whats weird is its acting like a bum water pump

It over heats at an idle but if im going down the road its perfectly fine. also the heater is blowing ice cold... heater core looks intact and no sign of leakage.

Also the car hesitates around the three grand mark...i have to drop the pedal to the floor to get it to go higher then that.

It *burps* every once in a while. I.E. I am sitting at a red light in gear with my foot on the brake and for no reason the rpms dip down to 200 to 300 for a sec then back up to normal and its sporadic when it does it.

I have no water in the oil to suggest blown head gasket and when I fill up with fuel to the full mark it runs uber lean until the 3/4 tank mark then runs fine, this all started after the power steering pump gave up the ghost...I have no clue where to start troubleshooting all these problems.

Im so lost right now, im trying to figure out what problems to address first to get it back on the road so I can get back to work but its all one big cluster F()&#!. The Spare parts I do have area 5speed transmission with a slightly rusted clutch and all the junk to install ita spare water pumpand 5 more thermostats sitting in the boxes...I have blown 3 since all of this has happened.

It means no circulation of coolant. You said water pump has been replaced. Radiator can be gunked up easier than other parts. Please touch lower hose and see it gets as hot as upper hose.

A guy I know had this problem had his KA completely rebuilt, so he was going nuts and didn't know what to do. Radiator was culprit.

[Maltrice]

both hoses get hot. and the whole radiator gets warm on all spots. cap fits snuggly with no leaks.

[keokitron5000]

have you flushed your system?if not take a water hose and take off the hose to your thermo housing and the hose to the top of the rad. stick the water hose in the top hose and if you have an air compressor stick an air nozzle in there too and wrap a towel or something around it and turn on the hose as much as you can to make sure water can flow through the block and keep doing it till the water comes out clear if it dosnt in the first place and the water should be coming out of the thermo housing.then take the rad cap off and undo both drain plugs and stick hose in top of rad, and repeat. only you wont be able to fit the air nozzle in there so just the hose and flush that baby.

for all of this you should drain your system first obviously.this will tell you if your getting circulation and clean out gunk.

good luck with the car.

There's a rubber flap on the cap and it should function properly to let the pressure out. It doesn't work properly if it's gets too old. I think that's why RJ said replace it.

Also, you might have a bad water pump. And yes i know you just put a new one in, but, as with my friends vert, when we rebuilt it, we put in a brand new oil pump, and a day after we started it, it went out. So not all new things work like they should.

I would try to get a new one, and see what happens. When it is off, take a hose and spray up the gullies on the block where the water pump sits and make sure you get water coming out where it should be.

If all else fails, I'd build up a new block and be set for life!

And as for it acting weird, the temp sensor isnt getting any heat to it most likley, or could be bad from the high heat, and that makes your car run bad if messed up.

[94_240sx]

But, you know it's not that easy to have a bad water pump. It goes bad because either there's a leak from the hole or blades are rusted bad like Eikon had. Belt turns the blades and that should do the job.

I want to ask you two things.

- Did you use OEM thermostat or generic one from auto part store?- What coolant are you using and what is mixture ratio?

Put thermostat in boiling water and see if they are really bad and don't open up.

On that note I bought a waterpump from autozone and put on my bonneville and it was bad and I had to take it back and put another one on it. Then it went out within a year so I went to Advanced Auto Parts the next time for one. Since the Autozone one's are junk.

To answer you guys questions...

I bought the thermostat from oriely's. I did the boil test before i put it in and it opened fine. I got the pump from orielys as well. I cant get oem parts here in town because the nissan dealership here blows. I live in a small backwoods redneck town in louisiana. if you arent related to someone that you married then good luck on getting anything done in this town. I'm moving to phoenix in a few months if I can ever get my car running right.

which brings me to a new question for the peeps pounding the streets in phx...what can i do to my exhaust system and still pass emissions??

[keokitron5000]

pretty much anythingand either throw some octaine booster in before your test or have a spare exhaust or put 2 cats on you new one.

but octaine booster should do fine and use premium gas. as all KA should be running on that with stock timing and everything of course.

A little orange bottle, RXP from Autozone works great.

went and bought a new radiator cap, drove it around town, let it idle for about 20 mins, and it didn't overheat! thank god it was a cheap fix...I can't believe I was abut to let my vert go over a 3.48 part...so with the left over money I got I went and ordered some new shoes for the vert, pics coming sometime tonight.

[94_240sx]

try getting a new radiator cap

RJ is the man, but he's trying to sell his vert.

[Maltrice]

I almost let some douche bag mechanic talk me into solving my problem for a vacuum leak... He wanted 127.00 up front and possibly even more during a recession... Are ya f***ing kidding me?

Anyway, if you're still experiencing that idle problem... plugs, wires, distributor cap, rotor, and hoses... Should fix it if it's still giving you issues. In whatever order you choose to go about it. Hoses are easy to check just pull on them in every spot to see if you see a crack or a leak... I wish that I had checked my hoses first as I replaced all of the above prior to checking the hoses. Your idle seems to be going as low as mine was.

[dallaceseiuli]

try emptying out your gas tank. and pumping only 91. for some reason that fixed mine. i guess after a long time of running 91 octane fixes everything. i am serious. i trried all that when my car had all those probs and it seemed to work.
