AzZo Posted April 26, 2013 Share Posted April 26, 2013 Question how important is the shield do you have to have it on? When you install headers do they come with shields.I was trying to take left side off but even with pb blaster I snapped one bolt off so I stopped the bolts are so rusty I am afraid if I continue I will just snap all the rest.I really wanted to check the manifold bolts to see if any need replacing.Can I run it with no heat shields? HELP IN IOWA UNSURE. Link to comment Share on other sites More sharing options...
Precise1 Posted April 27, 2013 Share Posted April 27, 2013 They are totally unimportant, you can run without them just fine. One of our resident mechanics says he just throws them away when doing manifold work. B Link to comment Share on other sites More sharing options...
ahardb0dy Posted April 28, 2013 Share Posted April 28, 2013 I actually removed one of mine recently to check the exhaust studs and all the shield bolts came out with out breaking, I was shocked Link to comment Share on other sites More sharing options...

Not much heat coming off manifold and plug wires are to high to be a problem and nothing else is to close so yea you are so right. Thank's Again, john.

THANKS FOR THE REPLY I am not going to worry about it and go a head and check out manifold bolt's. Have a slight ticking at start up that go's away when warmed up.

ahardb0dy Posted April 29, 2013 Share Posted April 29, 2013 My engine is a JDM engine so it seems it's in better shape than one that would have been in the truck Link to comment Share on other sites More sharing options...
hagge Posted March 10, 2014 Share Posted March 10, 2014 Hi! I borrow this thread for a trivial question regarding the heat shield bolts. What socket did you use to loosen the bolts? 9mm is to small and 10mm to big... Don't know if it should be an inch socket, would that be 3/8? (not familiar with inch measurements) I also have a ticking sound at warm up and would like to check the manifold studs. Link to comment Share on other sites More sharing options...
ahardb0dy Posted March 10, 2014 Share Posted March 10, 2014 they are 10MM, the bolt heads rust over time and may loose some metal, but they are 10's Link to comment Share on other sites More sharing options...
Thumper Posted March 12, 2014 Share Posted March 12, 2014 Guys, just browsing this topic. Going to have to remove mine as have broken studs and a set of extractors to go in. My question is I notice that both heat shields have what looks like a ground wire from body to the shield. If I take them off do I need to replace them?

Nefarious Posted March 12, 2014 Share Posted March 12, 2014 Yes, replace the ground wires. You do not want to develop potential at ground. Link to comment Share on other sites More sharing options...
Precise1 Posted March 12, 2014 Share Posted March 12, 2014 Yep, and they should attach to the manifold at the same place with the same bolt sans heat shield. B Link to comment Share on other sites More sharing options...
