I just became aware that modern semi truck engines have spin-on coolant filters. So, I got the bright idea....well just maybe my hot rod pickup ??? Maybe the combination of cast iron, steel, aluminum, and rubber might warrant such a deal on something that a hot rodder wants to take great care of. So please give me all the pro's and con's. I'll thank you ahead of time.....THANK YOU.
Yeah, heavy duty diesel engines have run coolant filters for many years. Besides removing contaminants they can also have a time-release feature for supplemental coolant additives, which help to keep the coolant charged and protect against corrosion and erosion of the cooling system. However, with modern extended life OAT type coolants, the time release of supplemental additives is not needed and not wanted, so they either use a straight filter or they turn them off completely when running OAT coolant. There is some benefit to filtering the coolant, but I don't think the benefits outweigh the cost and aggravation of retro-fitting one onto an old gasoline engine that never had one. Keep the system charged with fresh coolant in the proper ratio, and change it when due and you should be good to go.
Gano filters are available. They go in the rad hose. Many guys om the Model A site on FordBarn use them when trying to clean the cooling system. Paul in CT
I have used inline coolant filters that you put in the top hose 4 really dirty engines to filter out rust or what not. They can be bought through Jegs or Summit for pretty cheap in a few different sizes
Go for it! Don't even consider the amount of antifreeze that big trucks hold, nor the mileage they see every year. although many engines from the cars in the HAMB era, did not come from the factory with even an oil filter...
