New motor ,New water pump,New thermostate, New radiator, still gets hot.
anything I can try?thanks
2002 dodge ram,1500 4x4 slt 4.7 motor

 

Have you verified that with a temp gun?

 

Hooked up with scan tool live data reaches 190 in drive way parked for 1 hour running,but this morning got to work was reading 198 with live data and spitting out water

 

Was showing thermostat inactive too,got a new one in it

 

Was wondering if it could be the clutch on the fan

 

198 shouldn't be spitting anything..... You do have coolant in the radiator right? Not just straight water?

Keep in mind, your thermostat is likely 195 degrees.......

 

If it's spittin out water then it sounds to me like you've still got air in the system. Once it's cold uncap the coolant reservoir, start the truck and turn the heater on MAX inside the cab. You're gonna top off the coolant and just let this run until you notice the coolant level in the reservoir start to drop (whole time you're leaving it uncapped btw). You're gonna top it off as it lowers. Because the coolant reservoir is already at the highest point in the cooling system the truck will naturally burp itself of air once it gets up to temp. When you see the constant steady flow of coolant coming back into the reservoir from the return line and the coolant level in the reservoir remains steady, you're basically finished, but you can keep letting it run like that and burp the lines manually by squeezing the radiator hoses to give yourself extra ease of mind. All 4.7's have a bleed valve for the cooling system, but the bleed valve is lower than the coolant reservoir on our trucks 🤔. Whole time you're doing this you're gonna be constantly checking the temp gauge and the coolant reservoir, checking for leaks, etc.

If the truck overheats while doing this method, go ahead and pull the thermostat and throw it in a pot of boiling water; if it goes off at the temp it's supposed to, then it's either sticking because of the amount of crap and corrossion in your cooling system (which you'll be able to tell, it'll look nasty when you pull it out) OR you're dealing with a leak somewhere that you still haven't found in your cooling system OR you're getting a false reading from either your temp sensor, wiring or gauge.

 

4.7 can be a bugger to bleed with the reverse flow cooling system, crack the bleed screw or pop the upper rad hose and poor coolant down it and shove it back on. You could easily have an air pocket causing you issues.

I thought the 4.7 ran a 195-205 thermostat? I replaced mine with a 180 when serviced, do you know what temp you installed?
