Rumble's abilities have no cost related to them, and the use of his abilities is only limited by cooldowns. Instead, he uses HEAT as his secondary resource. Rumble starts with 0 HEAT, and it caps at 100.
While not overheated, after 4 seconds of not using his basic abilities he will start losing HEAT at a rate of 10 HEAT per second, then at a rate of 20 HEAT per second 2.5 seconds later.
