Here is a brief write up on an very easy thermostat swap with some pictures.
Need 10mm socket,
drain pans
vice grips
wire ties
First off..Here is the new thermostat..160 degree
Let truck cool and Remove your rap cap to realease the system pressure. When removing the lower rad hose, coolant will want to come out of the rad, but not the motor bescause the thermostat is presently closed. So at this point you need to be concerned with stopping the rad fluid from emptying the rad
I like to keep as much as possible inside, to prevent contamination. I like to take Two small vice grips and put one of each side of the hose to restrict leakage,(however, you can run the risk of collapsing some rad hoses) then after I pull the hose off wire tie it back up to stopp all fluid from emptying.
Now you need to remvoe the theremostat and housing, and let the rad fluid drain our into pans below the truck..there about 5 litres in there....
Install new Thermostat, un vice grip, and fill rad fluid...DONZO
