What causes the 53 block of coolant to crack?
Due to the lack of material in this area, the 53 blocks are susceptible to cracking — thereby leaking coolant — when the engine is exposed to heavy towing, high torque levels, elevated coolant pressure and instances of overheating. Cracking commonly occurs on the passenger side, just below the freeze plugs.
Why is the coolant not going to the heater?
It may happen that the thermostat gauge of your car is broken or not working properly. You might know that if the thermostat is not able to provide a signal to the car that the engine is hot, the coolant will not drive to the heater and the air will remain cool.
What are the shortcomings of a Cummins Engine?
1. Killer Dowel Pin (KDP) Due to its ability to completely trash an engine, the killer dowel pin tops our list of Cummins shortcomings. On the assembly line, a tiny steel dowel pin was pressed into the block of ’89 to ’02 mills in order to locate the engine’s timing gear housing.
What happens if you take the cam gear out of a Cummins?
Once it falls out, the tiny dowel pin usually makes contact with the cam gear first and can then be drawn into both the injection pump and crank gears, effectively making it a 10-cent wrecking ball. Remember, if it takes out the cam gear, the pistons will contact the valves, potentially leading to a trashed head and block.
Where is the coolant in the radiator when there is no leak?
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
What should you do when your car is losing coolant but no leak?
Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?
Can a coolant pressure test show no leaks?
The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks. Since the leak is not external, it may be getting burned. Maybe the intake gaskets leaking again?
Where does the coolant go when the car is running?
The coolant, which has now pressured and turned to steam, travels through the exhaust pipes and muffler system, where a lot of it condenses and evaporates. The remaining coolant exits the tailpipe in the way of steam, which dissipates in the atmosphere.
