yes man thats true

 

and today i in my rear Flow Muffler the stock comes only one side like it show here https://www.hummerforums.com/forum/m...91538-7986.jpg but what i did haha i didnt want to buy a new one but i needed to give it a good sound and cheap spending hmmm so on the opposite side of the muffler i cut a small circle same size of the original one and put the hose in the hole and Welding it very well and now i have a 2 way air exit muffler like that with a great sound not to noise but good and keep the car keep pressure in the muffler and the temp of the car will be a little slight down then before.

 

maybe as the smoke settles we can expect more of this prattle.
going from coolant to mufflers is hijacking i think but regardless a muffler mod cannot change engine temp.
in a normal,proper engine with normal coolant the temp is controlled by the tstat,ONLY as has been noted here even in 120 deg.
i cannot get my i5 quite up to midpoint,EVER, even when covering the grill with a blanket. never over 198,ever.

 

 

hahahah well just noticed that, but regarding the Car Radiator Water Pump Thermostat change it from hummer to Chevrolet Blazer item and the electric fan will do every thing.

 

Ever since the new radiator with the non-dexacool crap......the H3 has been running at 1/4 to mid-range everyday....I took a 360 mile drive yesterday and she never even got over 1/4 on the interstate at 80. Had the A/C on most of the time and it was a cool 80 degrees in FL. Gotta say the old radiator was complete crap and the new coolant rocks......with that continue on with your hijacking!

 

Your t-stat needs replaced!
Running to cool is not a good thing. Replace your t-stat and you will save on fuel and prevent excessive carbon inside the engine.
