Every now and then you get a vehicle in with a recuring issue, usually predated with several attempts at resolve.
This Z32 was receiving our Engine-Bay Restoration service with Motor Upgrades (cause with the VG30DETT out, why wouldn't you?) & 1 particular note before the commencement of the works was the lower hose has popped off several times from the radiator in the client's ownership.
There was evidence of previous attempts to resolve included glueing the hose to the outlet with gasket sealer, a double hoseclamp job & the customer has even paid for a thermostat replacement to not have a permanent resolution.
The client had anticipated replacing the unit BUT having an eye for the fine details & decades experiences makes looking at these sort of issues very straightforward.
Simple enough, the outlet pipe in question hasn't had a decent lip rolled into it at the manufacturing stage - there are tool marks where the lip was meant to be but barely had any edge to keep the hose secured...& obviously made it past the goalie mechanics to date.
Now this radiator doesn't appear to be of reputable brand BUT the vehicle never overheated or had issues maintaining temperature so with this is mind, we investigated before spending upgrade funds on an replacement.
Here @ConceptAutoInd we have a wide range of specialist tools for building custom fluid hardline systems & we achieved a neat solution with a specialty bead tool, some heat & a few hand rotations. With not replacing the radiator, the client had some spare upgrade$ for full set of silicone radiator & heater hoses supplied inhouse for a future proof cooling system.
