My mechanic says a 6.5 never steams out the exhaust

[nealpellecchia]

Gates belt 250,000 miles on it.

New tensioner and alt.

 

[Twisted Steel Performance]

Factory replacement O'Reilly's. Lifetime. No thermostat.

Well, their ya go,no stat.. and you wonder why it's hot ............

 

[nealpellecchia]

Had to take it out. Bottom of grapevine 2 yrs ago summer. Filled whole overflow tank.

 

[nealpellecchia]

Allowed me to go over hill.

 

[nealpellecchia]

Runs cool all over town. Then in summer head crack likely opens up...

 

[nealpellecchia]

Less pressure on combustion leak.

Not where from. Does the fanclutch bolt on to the waterpump with 4 bolts, or does the fan clutch spin on?

No thermostat will cause more rapid temp swings.

 

[Will L.]

A blown head gasket will create the same on the pressure in the entire system regardless of the thermostat.

It is possible you have a thermostat stuck closed, took that out and sold that overheating problem . However a lot of people think thermostats are not needed. If they didn't need him the manufacture would not lose a lot of its profit making them, and the housing for them-they would just use the fitting to attach a hose.

And if you hit hotter air?

Upper 90's is about as hot as I have driven in for any length of time in the last few years.... might add that my AC does not work so that is even less load on my engine.

Mechanics used to remove thermostats in the summer all the time. You needed it for heat in the winter they would say.

 

[nealpellecchia]

No thermostat in the summer slows the get hot from the combustion leak. You got the whole rad to cool with from the begining. A quick 190° then the leak pushes it up from there fast. At the grape vine I through buckets of water through the rad until the temp drops way down and then proceed slow over the mountain waving at stuck people.

A quick 190 with the stat in.

Throw...

I have never heard a mechanic say this.

I have heard alot of shade tree jerry-riggers say crap like this though...

A thermostat is needed to provide a little backpressure in the system to make sure coolant gets through all the passages and does not allow any steam pockets to form. It is very important.

Thermostat removal very well could have been the reason you now have a cracked head or blown head gasket.
