That means five to eight degrees of initial timing might not cut it these daysВ - especially in California, where the fuel has more additives. TodayвЂ™s fuels arenвЂ™t like our leaded fuels of the 1960s. However, these conditions can contribute to running hot. We should also state that if your timing or A/F ratioВ is so far off that youвЂ™re overheating, you should have already noticed the engine was running poorly and possibly knocking and/or pinging. Poor timing and poor air/fuel (A/F) ratioВ can also cause your engine to run warmer. Also, keep in mind that OE alternators from the 1960s may not provide enough juice to run electric fans. Never run a shroud on the grille side of the radiator, as it will block airflow. If youвЂ™re going to run electric fans, puller fans work best, especially with a shroud. Unless youвЂ™re climbing past that, let your engine find its norm by providing a proper-flowing cooling system. In fact, modern cars operate at 220-plus degrees. Many big-blocks are comfortable running at 205 to 210 degrees, and it wonвЂ™t hurt your engine at all. If youвЂ™re boiling over, youвЂ™ll need to solve the problem and figure out why, before you start throwing money at parts.Д®ven though your friendвЂ™s car might run at 180 degrees, thatвЂ™s not always the target temperature. A sufficient copper/brass radiator should cool your engine, providing you have sufficient airflow and proper coolant flow. While aluminum radiators can lower temperatures up to 15 degrees, they are not necessarily a solution for overheating. Will Aluminum Radiators Prevent Overheating?

After all, those products plug small holes вЂ“ and a radiator is a series of small holes to flow coolant. Remember, products designed to plug leaks are bad for your cooling system and should only be used as a temporary fix to get you home.

It also allows you to inspect the condition of your coolant without removing the cap. But keep in mind, a four-row radiator is going to require a much stronger cooling fan.ДЄn inline coolant filter, like this one from Champion Cooling, will help keep debris out of your radiator. The small, OE radiator from your 1967 small-block with its anemic 185 horsepower is not going to be the right radiator for your 450 horsepower LS-swapped Camaro. ItвЂ™s no surprise that size does matter when it comes to radiators. Mike reminded us, вЂњYou cannot have more than three-percent water/conventional coolant in your system with Evans waterless coolant.вЂќ He told us that you can mix water with it should you have a leak and need to fill the radiator to get home, but advised that you would need to flush your system again, as the water would diminish its effectiveness. In addition to the expense, you must thoroughly flush your system before adding it.

The bottom line is, a glycol-based coolant is more cost-effective, and with a well-maintained cooling system, it can perform rather well.Д«ut, there are some drawbacks to the use of waterless coolant. вЂњAlso, because of its non-corrosive properties, it can last for decades without needing replacement.вЂќ A typical glycol-based coolant should be replaced every three to five years.ДЇor a daily driver, though, Mike told us that upgrading to a waterless coolant might not be necessary.

вЂњWaterless coolant can help prolong engine life because of the lower pressures achieved in the cooling system,вЂќ Mike said. Of course, dirty coolant should always be changed, but Evans wonвЂ™t break down over time. Evans tells us that its waterless coolant will last much longer than conventional coolants, which should be changed every few years or when itвЂ™s dirty.
