NO WAY!!!!!!
Go buy yourself a radiator and some new hoses and new clamps. Get you some new GREEN antifreeze.
CHange that yourself for about one fourth the cost.
WHY pay him all that labor?
The radiator is NOT that HARD to change out, seriously.... If you lived closer I might do it for ya for the cost of parts plus $150.00 labor.
YOU however can do it for the price of the parts which is under $175.00
COme on De! Time to get your hands dirty....
