No....It didnt explode on me.

If you have a 90 accord im not sure which is the nozzle you put it in but I know it should have a blue cap on it.

I know you need to have the car on with the A/C running while your pumping it in there.

They also sell cans that have like a sealer type of liquid in there.
Might wanna use something like that in case you have leaks.
