Hi, I had my thermostat and water pump replaced and the car is still overheating Mechanic's Assistant: Has the vehicle ever overheated? And when was it last serviced? Never overheated and it was last serviced a week ago when I got the water pump and thermostat put in Mechanic's Assistant: What is the make/model/year of your car? 2014 Mercedes cla [250](/topics-250/) I’m hesitant to take it back to Mercedes bc I’m no longer under warranty and it’s $200 for them just to look at it Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? I had a professional technician put the new parts in ..which include water pump, thermostat, auxiliary pump and [coolant](/topics-coolant-mercedes/) Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? The car has gotten a block test and the fluid was still blue, so it passed that test and the radiator would be my next guess but the fan is working fine ...and also the car is over heating when I’m on a straight away Not when I stop and go

Hi! My name is \*\*\*\*\* \*\*\*\*\* I will be able to assist you. I’m sorry that you’re having trouble with your vehicle. Don’t worry though, we’ll be able to figure this out. Please understand that I do not know your knowledge or capabilities so I **may** need to ask questions to find out basic information to help solve your specific problem. Sometimes I have to look up some information so it may take a moment to respond. I appreciate your patience. The system will give you an automated phone call offer to speak to one of us on the phone **. It is optional.** Some folks prefer to talk on the phone. If you don’t, please ignore it as I cannot control the offer from popping up. There is either air trapped in the system or the radiator is blocked up. I'm not sure why the technician that installed those parts is not fixing this for free but you'll need to bleed the air out of the system. If all the air is out and it's still overheating then you'll need to check the temperature on the radiator to see if one side of it is much cooler than the other. If that's the case then your radiator is blocked up.
