How do I take the radiator off a GMC Sonoma?

Answer by  kennethjgoodson (4903)

You are going to want to go to the bottom of the radiator and open the petcock, It will drain the fluid and then you will need to undo the hoses and the bolts holding it to the brackets.

first flush the radiator then remove the hoses make sure to plug the hoses to keep dirt from geting into them, unbolt the radiator from where it is mounted after you have unbolted the radiator remove it and put the replacement radiator in, bolt it down and connect the hoses back up to it

This is a very dangerous task for a novice. It might be best to check with your local auto motive expert if you don't feel quite up to the task. First start by killing your engine and make sure the engine is cool before you begin. The Radiator will be held in place by several strong bolts. You need wrenches.

You are going to want to drain the coolant from the radiator and then you can take your hoses off. Once you get the hoses off you can uninstall the bolts holding it on. You can then install the new radiator.

You can go get a manual for the car at an auto parts store, the manual may tell you how to fix it. Or you might have to take it in to have it fixed by a professional. They would know how to take it off. Or look it up online.

This is a very complex task that I can't describe in detail here. Also I don't know what year of truck you have and the process will vary from year to year. I would recommend looking online for information and possible purchasing a service or repair manual to use as a guide.

Look at bottom of radiator to open petcock. Flush radiator and remove hoses. Plug hoses to keep dirt from getting into it. Unscrew radiator from mounting after unbolting it. Remove old one and put new one in. Rebolt down and put hoses back on it.

The radiator works by flowing fresh air from the outside of the engine bay...That maybe how it works. But I still did'nt answer the question...I don't even know how because I don't have a GMC Sonoma but you should take the radiator of a GMC Sonoma from its engine...

The radiator off a GMC Somona is connected to the channels which are runnig through the cylinder. You can remove it yourself or consult a machanic.
