... designated shop as prescribed by the warranty company. they diagnosed the cooler need changed and the warrantee declines payment for the payment because, they requested the oil cooler tested which did notfail on testing only because it was tested at a psi that was below prescribed indicated. so I had to pay for the whole work done to my truck with no help from the warrantee company, further more, the mechanic shop made sure I changed things there not bad in the truck and charged me top $$$ labor for it. yet the problem still not fixed. what can I do?
