I have now changed a THIRD garbage Chinese coolant overflow container because it too started leaking. If it weren't for the warranty from the auto parts store I'd strap it to a missile and send it back to PingPong's office in Beijing. Sick and tired of having to carry jugs of coolant in the cargo area...

 

Why in the wide, wide world of sports would the overflow tank shoot a jet of coolant out the side, either when driving, or when I try to remove the cap when the engine is hot?

 

I have a functional used OEM tank if you need it. The float valve doesn't work but you could jumper it.

 

Thanks, I found the hole on the side of the tank. Monday I am going to ream the mechanic a new one.

 

I will be replacing the coolant reservoir on my sister's car (not an LR2). After reading reviews, I'm braced for the possibility that it may develop a small crack and leak. I don't know why it's so difficult to make a non-leaking tank, but that appears to be the case for some of these aftermarket parts.

If that happens, I don't want the hassle of replacing the tank until I get lucky. So I was thinking of this repair solution as "Plan B". What do you think?

 

I thought about reinforcing mine with a layer of epoxy.

 

Hmm. Not sure about that with a pressurized tank.

Maybe wrap it in fiberglass, get a cheap kit from flaps?

 

Umm... Reinforcing <> Plugging the pressure relief ports. That would be über-stupid, and while I am crazy, I am not stupid, There is a difference.

It means reinforcing the container to prevent structural failures like cracks.

 

Just saying not sure than an epoxy coating would help much, not too much strength in tension. Fiberglass has some tension strength, thanks to the fiber part.

 

It also adds thickness, which may make it difficult to refit the part.
