Buying a o2 sensor tonight and was reading about other guys overheating and read where somebody said Green coolant only. Mine has red and it never get above 192 but will stay around 180 average


Ultra gauge says bank one sensor 1

 

Bank 1 is the drivers side. At your trucks mileage why are you replacing just one 02?
Not sure who coolant is Red, you should be running green or yellow, like Peak.

 

Looks like dexcool,

bank one is drivers side eh? sensor one is closest to engine?

 

Would stay away from Dexcool (orange) - turns into sludge. green or yellow good.

 

Coming from VW/Audi's I've always had great success with the purple VW G12+ coolant. Comes in either 1.5 litre or 1 gallon concentrated bottle. Aluminum safe as well as phosphate and silica free.. Just dont mistake it for grape drink...

 

DI's came with standard green coolant, changed every 30k or 36months, whichever is sooner per the owners manual.

 

what the dif? and do you guys use distilled?

 

I buy it 50/50 premixed, its idiot proof, just pour it in and go, plus you get the full warranty from the coolant company.

 

I do use water wetter or purple ICE any of you guys use that stuff?

 

Nope. I do not believe in snake oil's, if you need to add a additive to your motor oil, power steering, transmission, coolant etc. then you either have a problem that needs to be fixed or you need to use a different fluid.

Engines are designed to run at a certain temp, what is the point in trying to lower the temp as much as possible?
How much does this crap lower the temp buy?
If you want a colder running engine then just put in a colder t-stat.
It did not come from the factory with extra crap in the radiator, or the engine oil or the transmission, so why add it now?
I just dont get it.
Each to their own.
