Ok Debbi, I will spell it out since my husband is a mechanic and I do all the pricing for his clients.
I got that fixed replaced a hose, replaced radiator cap, intensive labor (or so company said) to the tune of 1000 bucks. (this job should have cost no more then 100.00-150.00 depending on labor cost, its not intensive labor unless you have no hands and can't fig out where the cap goes.) Now, the car needs water pump, new timing chain, and more intensive labor required (so the company says) to the tune of 1200 bucks.( 400.00-500.00 depending on how hard it is to get to the timing chain, you take on my truck it would take a good hour or two just to get into the motor to get at the chain)
My question, when do you stop? First I would find a better mechanic that dosn't charge what this shop you went to did. Find a good and honest mechanic in these days with the economy you should be able to find one that is willing to deal on the labor which I would not pay more then 75.00 an hour. This shop you went to ripped you off I would let the BBB know.
