Hi. I think I need a new injector cup but will it need all. Is it fine to drive because it's a plow truck and I need it tonight? Please need help!!!

 

Back to top for you.

No you don't need to do all the injector cups, but unless you know which one is leaking, you won't know what side to start on or which one to do.

I'm sure you can drive it (I know this response is later than you needed) but it's ruining your coolant and is only going to get worse.
