Diesel89 Posted January 21, 2021 Share Posted January 21, 2021 (edited) Hello there, I'm new to the Forum. I hope I'm not barging in on a conversation at the wrong topic. I've recently got my front water pump housing tore down to replace with a new one, and a lot of the bolts seemed extremely hard coming out of the front cover - two of them were broken (fan hub bracket studs). Can anybody tell me if Mack recommends anti-seize on any of the accessory bolts in this cover? Edited January 21, 2021 by Diesel89 Quote Link to comment Share on other sites More sharing options...
Diesel Man Posted January 21, 2021 Share Posted January 21, 2021 Hey diesel89, I cant see were it would hurt any to do that, anti-seize is always a good friend of mine especially when bolts break, new ones normally turn gray before they go back in. If you have a tap and die set might want to clean the bolt holes up and the threads on the old bolts. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted January 21, 2021 Share Posted January 21, 2021 Good clean bolts with or without anti seize will work... they only torque to 33 lbft.. so I'm guessing someone put them in with a 1/2" gun before you got it...😃 Yes... chase the threads... jojo Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted January 22, 2021 Share Posted January 22, 2021 Adding any lubricant to the bolts will change the torque value. If the OEM does not mention adding anti seize or lubricants to the threads I would advise against it. JoJo said it correctly, clean bolts is all that is needed.
