On the flip side of a valve cover gasket replacement and SAI port cleaning.

Heat exchangers came off fairly easily (front drivers side is fun and managed to extract stud and all from head on one hex fastener) and have been looking to see if there is a specified torque setting for reattaching the hex and lock nuts but have not been able to find anything.

Does anyone know if there is a proper setting or do you just crank them down tight?

Thanks, Rick

just a thought here, I think you're supposed to replace the nuts and gaskets with new, also the brass gaskets from heat exchanger to cat.

Also, a good idea to put some anti-seize paste on the threads so next time they come off like butter.

Exhaust sealing rings part number if you want to go with new:

Also, place 2 - 3 dabs of anti-seize in the recess where the exhaust sealing rings go, then put the rings in place. The anti-seize will keep the rings in place while you put the exchangers back on.

Thanks ALL!

Exchangers with new parts in on the drives side. Appreciate all the tips. Anti sieze and grease tip to hold the rings in place really helped. Doing this by yourself, on your back had me thinking I was going to need three hands.

Couldn't get a torque read on the one nut that needed 1/4 drive to get at it. Think they could have designed the heat exchanger a little differently in that spot, but its on tight.

On to the passenger side today and hopefully new cats in today as well.

Buy yourself a 3/8" to 1/4" adapter, they come in handy sometimes and not just for torquing.

Thanks Bill, adding to the tools list. My wife now calls these my accessories purchases.......which as the list goes has required a new tool chest to hold everything, heater for the garage.....and the list goes on.

I have reused the metal rings over the years, no issues there. I also use Copper nuts instead of steel, they seem to be easier to take off later - and use high-temp anti-seize of couse.

Hi

You can get 12mm copper coated steel nuts which have worked well on my car and are more accessible than the 13mm alternatives. I think they are used by Esprit turbo owners.

Tell the wife tools are man jewelry and or equivalent to shoes

My wife stopped asking after that ;-)
