Exhaust Manifold Heat Shield

  • I installed this a few weeks ago on my stock manifold... I just saw something in an unrelated previous thread about possibly causing the engine to run hotter. Anybody have any first hand info on this?

    No Chance of making the Engine Run Hotter

    this 1st hand info with the GM Heat Shied as shown


    i have a temp gauge that reads water temp in engine (the hottest water in the system) and coming out of the top of the radiator (that is the coolest water))

    have drove over 10,000 miles have been in 105 degree temps in stop & go traffic

    on a 98 degree day cruising at 80 mph temp does not go over 180 degrees in engine, 170 degrees coming out of the top of radiator

    "Trust Me No-Overheating" "that u can take to the Bank""
