I have a 2001 dodge grand caravan 3.8, I replaced the power steering cooler complete unit. it ran great for a month and blew back off again, any suggestions to solve this problem would be helpful.???????

 

The two hoses coming off the cooler blew a couple times. The issue was the power steering reservoir was clogged (terribly). While I was at it I put a new cooler, reservoir (about $25 each) and high pressure hose/transmission line (bulk) about $8. FWIW, if you want to try the repair and not too mechanically inclined, drop me a pm and I'll give you the steps.
