Hey, I did a search but couldn't find anything about this. I put a 4age in my ae82 sedan, The idle is hunting and i searched around and found most likely its because of a air bubble in the cooling system but before i found out about that i thought maybe it was the power steering lines. Because my car does not have power steering i took the P/S pump off the engine.

 

There is still 2 vac hoses that go from the throttle body to the steering rack. When i started the engine idle was a steady 2,600rpm when i blocked it off it was about 2,000rpm. My mate pulled one hose off then put the other one in a loop back into the throttle body and it sits at about 2000rpm. Is that ok to do that or should i do something else.

 

The idle is still jumping up and down from 900 to 2000 but I'm going to bleed the cooling system tomorrow. Just want to know if its safe to block off the power steering lines or loop them?

 

Thanks in advance, Johno

Just block them, They are from factory when no P/S is installed.

Cool, thanks Trev. Everything else is pretty good. just The alternator is making a whining noise but I think thats because the battery is dead flat. I'll buy a new one this weekend.

don't think the battery will be the issue with that alternator.

 

did you start the car with said battery? if you did then it can't be too bad.

 

maybe you might have stuffed bearings in your alternator...see how you go though.

The Alternator can make a whining noise if its putting out alot of current, i.e flat battery or low on charge. But also if it hase a diode problem, basiclly if the current is high, 30+ amps don't worry, recharge your battery on a charger over night and the noise should reduce.

 

If the noise is a grumbling sound, then it may have a bearing fault, pull the belt off and spin the pully and have a listen

Ok, power steering vac hose has been fixed, Thanks Trev :)

 

Idle Hunting has stopped since i got all the air out of the system.

 

Now as for the alternator noise, I bought a new bettery today and started it up, the noise has almost stopped. It was whining like a supercharger before and getting louder as the engine reved more. Its still there slightly but its hardly noticable now. Its still runnung without an exhaust so i can't hear much when its on but yeah.. :jamie:
