rear coolant crossover tube

Well I was hoping today that I could finally start my car up, so I started to put the coolant in and I noticed that it was leaking from the back of the engine. Felt like the back of the passenger side head was a little wet so it must be coming from the crossover tube. Can I just replace that little gasket on the back of it or do I need to get a whole new tube??? What type of gasket/washer do I use if I just replace that? I hope its only from the tube but I don't know where else it could be coming from.

yes, you can replace the gaskets. you will need a total of 4, to do both sides.

Four, 2 are used on each side and "sandwich" the fitting.

Re: rear coolant crossover tube

unless you broke the tube, that is the only thing that leak from that area.
