SuperCoupe8 Posted May 2, 2020 Share Posted May 2, 2020 Hi Guys Working on my thermostat and spring loaded valve body. I bolted it in and have coolant pouring out of the top one of the bolt head. looking inside the body I see a hole that the bolt passes by that the coolant is leaking from . What is that hole for and should it be Welsh plugged ........ any pictures or guidance would be great cause I cant find anything in the manuals.

pont35cpe Posted May 2, 2020 Share Posted May 2, 2020 It looks normal to me. Only thing i notice is you have a lock washer on the mounting bolt, should have a flat copper washer. 2 Link to comment Share on other sites More sharing options...
Glassesguy Posted May 2, 2020 Share Posted May 2, 2020 Yes, flat copper washer. This is open to the water jacket. 1 Link to comment Share on other sites More sharing options...
neil morse Posted May 2, 2020 Share Posted May 2, 2020 As has been said, you need compressible copper washers on those bolts to seal them. Plus a bit of RTV sealant on them is good for insurance. 3 Link to comment Share on other sites More sharing options...
