💡 How do you stop hot spots when refreshing coolant in a big rig cooling system?
Running the right chemicals makes the whole job pretty handy for mechanics.
- Measure exact gallon capacity before pouring new inhibitor pack into the reservoir
- Watch pressure gauges until bubbles clear out from high point bleeder valves
- Check temp sensors repeatedly to confirm steady readings across the radiator face
- Park the motor overnight so fresh chemistry settles over cylinder head gaskets
