Leaking Radiator

[theponyremark]

Hi All,

I appear to have a leaking radiator from the top tank. It appears to be leaking from the right-hand side and slowly flow over the left. Would this be repairable? What are the options that I have?

If it helps, it's not any of the pipes or obvious cracks I can see. It takes coolant overflow bottle to go low after a few days with or without the air conditioner on.

you may be able to buy the seals for the tanks, but it may be cheaper to buy a new/used radiator instead of paying someone to tear yours apart and repair it

hey, my radiator sometimes does this and the water runs all over the top tank making it look like the seal is leaking but we found out it was the connection from the top tank too the hose. The water was trickling out the hose and drop by drop landed on the radiator and spread over it. Just check the hose has not slipped back and letting the water seap out.

I once changed a top tank and used the company Natrad, they charged $78 too change it, pressure test and flush. (Get the top tank from a wreckers)

hes got a point. it is possible to for leak to be coming from the top hose. also check that the hose clamp itself has not cut into the hose and causing it to leak throu the hose.

Thanks for your replies!!!

In that case, where could I purchase a replacement hose for the R34 overflow bottle to the top of the radiator cap? I tried JustJap and it seems they just have silicone hoses to the engine block.

That hose is just overflow hose, its sold at super cheap auto by the meter. There are different diameters so best to bring a piece in or if you can get the size with a caliper gauge use that too buy the right size hose.
