POWER STEERING PUMP

[HEEP4me]

 I have a 1992 chevy 4.3 in my CJ. The pump was weeping oil out the seal when I installed the motor. I am using the stock jeep box with the chevy pump. After a couple runs the front seal on the pump gave up. My buddy gave me another pump off a V8 that matched mine. I installed it and drove it around town a few times and everything was fine. As soon as I went on a run and had everything locked up and I turned the wheel to full lock the pump started to howl real bad. I let it cool for a few minutes and unlocked 1 hub and that helped but it would still get angry. Now I see that the front seal is stating to drip on this pump as well. The jeep pump looks the same as the chevy pump but I no longer have it. Is there a reason this is happening or just bad luck???

What size tire are you running?

[Mikegyver1]

I'd try doing the pump mod. and adding stop leak see if that take care of it. I'm guessing these are old pumps that were sitting without fluid in them? I think the seals may shrink up without fluid...

 I have 33s. I did get a seal kit from kragen and will try that. Dont know how long they sat.

also run a cooler   those chevy pumps dont like to get hot

[HEEP4me]

Any ideas on a CHEAP cooler. In the old days we used some on our modified ATC 90's. One of those would be great if I could find one.

Aren't pumps also different between rack and pinion and steering boxes? f Different pressures needed thus different valving in the pump. 

[84socal]

the chevy trucks with that era motor dind have rack and pinion   they have steering boxes as well


and a cheap cooler     go to vatozone   or pepboys u can get a decent sized transcooler  for 50 dollars
or u can order one online   form place like kartek  or mckenzies

a plate-fin cooler will cool better than a tube and fin cooler

but a good inline will cool better than both of those 

[HEEP4me]

 Thanks.  The S-10 was a box.

 I put a new front seal in my pump.
 Kragen has a cooler for $29.
 I will get a couple small fans on the cooler as well. They run about $5 each.

[HEEP4me]

 Well this is what I came up with. Everything seems to be ok. I have about  $40 in it. I have the fans turn on when the key is on. I was really suprised how Hot the cooler got. 

[Mikegyver1]

Very nice... I have a few of those fans. Great idea 

[84socal]

the reason the cooler is getting hott is because i has no airflow gong through it   put that thing behind ur grill  and that will keep it cool

[HEEP4me]

Its hard to tell in the pic but the cooler is spaced off the fenderwell. Those fans blow pretty well. I was just suprised to see how hot the oil actually gets without even working it hard. This should make a big difference. I didnt want it  in the grill because I have no fan shroud and air flow is minimal. I have a large radiator that keeps it cool so I didnt opt for a custom shroud due to $$$. 

[84socal]

i see thats it spaced out a bit   but the fact is u are pushing around hot air right there in the engine bay   it kinda the same concept of a radiator   and why they mount them where air flows through it  though the grill  u will overheat that pump again    u wont really cool it where it is right there   and moun it in front of the radiator

[HEEP4me]

 I understand the concept. You cant see it but its got large openings for air just under it. This is better then what I had with nothing. If it still gives me trouble I will make a heat exchanger..

 

[jeepsterrob72]

if you put it in fornm of the rad  it will cool without the fans even on so you can hook it up to a temp sensor. chances are if you are getting engine bay air you arent acooling it at all even if you are blowing air through it.

[HEEP4me]

  As I stated earlier I DON'T have a fan schroud and the fan is not very close to the radiator. I have a large 3 core and it does not overheat, but it dioesnt pull much air through at low speeds and I don't feel it will cool any better then in the egine bay that has alot of open areas just underneath for cool air . THANKS

[jeepsterrob72]

lol, dont get mad dude

[HEEP4me]

 Its all good, If i have a problem I can re engineer it. I know its MUCH better then the way it was.

[jeepsterrob72]

i ahve mine in front of the rad with an elctric fan and it helps draw more air through the rad and keeps the whole ride cooler, something to think about.
