98 acura engine overheating

[sinch]

I have a 98 acura CL 2.0. I recently had the head gasket, water pump, timing belt, spark plugs and wires, temperature sensor and radiator replaced. Also, the thermostat was removed. However, I have had problems with the engine overheating when stopped at red lights or in heavy stop and go traffic. The fans are working. Hoses were replaced. Garage that I have been taking the car to for the repairs can not figure out what is wrong with the car. If it continues to overheat...I am worried that the head gasket is going to crack again. I have been going through a lot of coolant. There are no leaks. Hopefully someone has some suggestions on what may be causing the car to overheat!!!
