I've been adding 1 litre of power steering fluid in the past 3 weeks and finally found the time to look for the leak. Nothing near the pump, but a big leak in the connections under the air filter, directly behind the driver's side headlight. A mechanic said this was the power steering cooler but I can't find anything in the book on this.

Lines are pretty corroded and lots of oil leaking into the wheel well, probably from air pushing it in.

Seems to be a hard place to get at. I searched here and couldn't find any threads on this. Can someone point me to a thread or offer advice on whether this is a garage job or do-it-yourselfer?

Thanks, Doug

try some lucas power steering stop leak

Come back in a week or two and see what happens.

 

The stuff I used was 'stop leak' but not Lucas Brand. I'll try that next but I think the leak is too much for it to work.

Any other ideas on whether there is separate cooler for power steering or does this go through the trani cooler?

 

If you have the trailer tow package you will have a cooler. I just replaced mine as it was leaking due to a rusted out tube.

 

For those that are searching later ... my leak was in the aluminum tube section where it bends 90 deg and goes through the wall behind the headlights. I simply removed the driver's side headlight, washer resevoir, pried the front grill assembly back a bit and power washed the mess under it. The aluminum had corroded badly. I bought 3 ft of new rubber line & some clamps and replaced the bad section coming from the power steering. It took 30 minutes and I really had no idea what I was looking for.

I probably have the tow package - thanks for that - bought the Blazer used so not sure. I had never seen a ps cooler coil before and everyone I talked to hadn't either.

Anyway, fix cost $15. and I have no idea what a new cooler would cost at the dealer - way over what I would want to spend.
