99 under intake return pipe

[gmartin888]

Hi everyone. I've been reading the tech article on this heater pipe but do not see the 98 and up model. I'm trying to replace it and that pipe is solid and I don't see any hose clamp on it. Anyone replace them before? Thanks!

When I replaced the intake on my 2001, the pipe is a solid piece pressed in to the block behind the water pump....exits out back under the manifold to connect to the heater hose....

Nope, no clamps....does not need to be replaced unless the cooling system is trashed and pipe is rusted through and leaking....
