I purchased a 2003 P71. It was an FBI Command Car. 127K miles on it. New tires, brakes, etc...
I did notice that the oil cooler lines were leaking on both ends.
I looked up on this forum how to replace them. I purchased the hoses for about $40.00.
I also read that the bold on the oil cooler side has a bad habit of breaking off. Well mine did.
I ended up drilling out the hole and putting in what I think is a zinc dipped over steel self tapping hex bolt. It might be aluminum / zinc dipped.
The bolt I used is zinc dipped and has a heat rating of 250 degrees and rust resistant.
Do you think I should replace that bolt with something like stainless steel?
The bolt I have on there now is real tight and I don't fear it will work loose or anything just don't want it to break from heat. Also I don't really want to remove it because it is tight and self tapped in there. Just a little concerned.
I think you answered your own question. Everything you said sounds ok. I would just leave it in and watch it for awhile. I think you have a good feeling about it and if you change it, then it might not be such a good fit...
