Noticed a strong smell of antifreeze from outside the vehicle after turning it off. Then began to notice fluid leaking from under right rear quarter behind the wheel. Took vehicle to webb Chevrolet. Diagnosis was faulty coolant lines running into other lines forcing a leak of coolant. I wasn't to clear on diagnosis, but they had to order parts and we lost the vehicle for 3 days.
