How hard will it be for me to change radiator in my truck?

I have never replaced a radiator before but it looks pretty simple, take the fan cover off remove all the hoses and tubes from the radiator put the new one in and reconnect hoses. My truck is a 1990 Chevy K1500 5.7 350 TBI. Does any one know any common problems that may occur well replacing my radiator, or how hard it will be thanks.|||it is a pretty simple job on that one ,you have to drain the cooling system out on it first then remove the transmission lines from it then the rest is fairly easy,remember to refill everything once all this is done,and check the transmission fluid you,ll loose a small amount on it,good luck.|||You had already explained what you needed to do, so go for it already.|||You pretty much have it.





tho, I would recommend removing the mounting bolts holding it in before trying to take it out.|||I%26#039;ll state the obvious - drain all the water first.





Commonest problem is air locks in the system. You have to fill it from the bottom up, put a water hose into the bottom hose and push water through until it starts to flow out of the engine side of that bottom hose connection.


Connect up the hose, top up the overflow tank, start the engine and let it circulate with the rad cap OFF so you can see it bubbling around, give a few minutes, turn off, let it cool top up again as needed replace cap.





That should do it.





Check your hose connections after a day or two, they will probably take another turn or two of the screwdriver.
