You’ve lastly made it to the nicer weather and on those hot days, you observe that your Rat Rod is running far warmer than you would like. The first thing you have to determine is if everything is working properly.

Go with the obvious first. Is the radiator of your Rat Rod without any clogs? Is there a develop of calcium within the radiator and not allowing it to cool effectively? Lets check hose pipes. Exist any leakages with them, or in truth are there any leaks to the whole system? Squeeze the hose pipes. They can collapse after they have actually become worn and obstruct the circulation of cool fluid. Likewise, lets examine the water pump. You can inform when its streaming by looking inside the radiator and searching for coolant motion. If all these check out, pressure test the whole system. Make certain that the radiator fluid is not mixing with engine oil.
Lets not forget the obvious. Check that thermostat or eliminate it to ensure that it is not the issue. You wont need it for the summer anyway.
If all of these concerns have a look at ok, then you need to update your cooling system to make up for your heat issues. If you are running a clutch fan, check to make sure the clutch is working. If need be, include a “pusher” fan in front of the radiator to help in the cooling for your Rat Rod. Newer radiators are made of aluminum and dissipate the heat much better then a brass/copper style radiator. Although they come at a rate, they generally are much smaller sized then the originals, and eliminate the heat much faster and more effectively than the old style.
The style of your Rat Rod can impede the efficiency of your cooling system also. If you are running the basic grille, the circulation of air ought to be no problem. But if you attempt to change the circulation of air to the radiator by changing the appearance of the front end by adding shrouds or expensive bodywork, this can trigger an overheating condition. Although you have fans, the natural circulation of air, for example at highway speeds, is needed. As the RPM’s of the engine increase, so does the demand for extra cooling. Overdrive transmissions do help by minimizing the equipment and hence reducing the RPM’s, however never forget about the airflow to your cooling.
