Okay - let's start off I want NO SYMPATHY here. It is what it is. Anyway......I have a 93 Deville owned in family since new. Now it's at a tick below 90k miles. From a "need" standpoint, I dont need the car...I have another daily driver and a different "backup". This is my 3rd car. I like it...and think its sort of a respect factor to my parents/grandparents to take care ot it. Normally I do my own stuff, but work took precedence - so whatever.

Fall 2008 I took my car to a local "trusted" shop to have my coolant system for its annual flush/refill of coolant and supplement tabs. The car was bought Nov 1992 and has been a ritual since. It got a clean bill of health and we moved on. Car garaged. My parents know the owner of the shop I took it to, but he's pretty disconnected from the day to day operations of the shop.

Come late Winter 2008 (2 mo later) ...little heat. Take it back to the same shop, they say the heater core must be clogged and needs to be replaced. Per my request, they reluctantly did a more intensive flush with the same result. I let it go until recently.

Between the "Little Heat" and now, I learned I had Leukimia, advanced stage. I have to think the owner of the shop knows, as he and my parents talk often.

Now...I have everything under control healthwise and things are looking better. Work has slowed down and since I've been feeling a lot better, I swapped out the core last weekend.

Still, no (or very very little) heat.
Did some reading here and find info on the "T". Pop the hood and find the T is REVERSED. The restrictor is on the drivers side of the T.
I switched the T and viola....HEAT!!

so I ran it by the owner of the before-mentioned shop. Owner brings his Cadillac mechanic over. Said mechanic says there's no way the T could have been reversed for a year. If it was, the car would be toast. It would have overheated LONG before now. It will ONLY cool properly if the T was right and he would have immediately noticed that.

My question is...............how possible is it for
A - something have taken place to generate interest in said shop performing core replacement (estimate $600)
B - Something fishy taken place at the shop to initiate my interest in having them perform the repair.

Please advise - I'm not out to judge anyone - just looking for honest opions.
