David's Build Thread

[Davidbolam]

I cannot get the thermostat housing to move. The bolts seemed to be really soft as though they were aluminium.

I've managed to remove the thermostat cover and I have about 4-5mm of bolt showing. Any other way of doing it other than welding?

As long as you can apply heat and grip and turn the stud it should come out

I assume you have handed the welder back if you do need one you could come borrow mine for a day or 2

I had a similar issue on my manifold block, the way I tackled it was to drill a 3-4mm hole in the centre then slam an oversized torz bit into the hole. Hit the torx bit fairly hard to try and 'jar' the bolt, then put a socket it on it and wind it out... it may not work if the material is as soft as you say but it worked for me in the past when all else fails

hence why me and half pint nick named the car 'bolt'...

My vote goes for welding something to the studs, too. I had also used a stud extractor on a broken exhaust stud successfully.

Another method I have had great succes with is to put a cut down the side of where the stud/bolt is mounted and open it slightly with the right sized chisel and as you say David nut and bolt.

If you are stuck give me the nod.
