V6 Thermostat Housing, another way?

[Saga Lout]

I've done this to a housing, you'll either like it or be afraid of it. I drilled into the sonic welded part of the rim, I then ran a tap down to create a thread and then I put in a grub screw, the grub screw is filled with thread lock glue and it should make the housing ultra strong. I don't see how this could break as there's no longer a weak spot and it might just be an answer to more expensive options, it's cost me a full £1 in bits to do this.

I did something similar back in 2013 it never got fitted to a car, i don't know what became of it, maybe still in a box in the shed somewhere?

I think we now know most leaks are due to the O-ring being flattened on the housing.

Thanks for pointing this out Steve. I've been posting about it for quite some time now.

You could carry out a useful experiment Michael. Fit your modified housing to your V6 and deliberately set the straight pipe clips in the wrong position; fully inwards, then see how long it remains leak-free. Leave everything else standard factory spec.

To both Steve and Simon, I'll put it on but with the info supplied by your good selves I'll do another mod. I'm vapour blasting all the alloy parts and the last thing I want are new stains! I'll make a bracket that will hold everything tight and in the correct place.

Hi Michael,

I can understand your reasons for doing that but unfortunately making two changes at the same time won't help to confirm the true cause of the coolant leak.

I'll be very interested to see how effective your bracket turns out to be. Please remember to post details, with photographs, of the construction and fitting!
