    Mas madali i mainatain yung brass radiator. If may leak dali i weld and dali rin mag pa overhaul.

    yung radiator ko may leak sa kabitan ng hose sa upper. i'm thinking since matagal na rin palitan ko na.

    Palit lang ng brass yung kabitan ng hose at ok na yan. Ganyan din yung crosswind ko.

    True. Brass is more corrosion resistant than aluminum and easier to repair.

    But be very careful with these "overhauling" services. What they do is that they flush your radiator, then torch the tanks off, then poke the tubes with "alambre", then reassemble it while lathering it with copious amounts of lead solder.

    Several issues here.

    First, the tube walls are a mere 0.12 to 0.135 mm thick in typical car radiator tubes. So poking through that can abrade and risk damaging your tube walls possibly causing leaks.

    Second, the re-flow of solder can cause capillary flow of melted solder away from the joints they intend to seal, specifically on the header plate of the radiator. Again another potential issue for leaks.

    Third, the problem with these corner radiator chop shops is that their materials for soldering are suspect. Given their price points, most of them use recycled material or scrap discarded from primary manufacturing processes. What this in turn does is introduce a lot of impurities into the solder leaving cavities that can be potential causes for leaks.

    Fourth, the flux these shops also use, given their cost models, is likely zinc chloride. This is highly corrosive and it must be vigorously cleaned off areas where it was applied to otherwise it will result in oxidation and cavitation on the joint and metal surface. Yes it will lead to leaks.

    If you are conscious as well of the environmental impact lead poses, you'd be thinking twice what the true cost of cheap is.

    Kapag palagi brand new radiator ang bibilhin ng mga car owner, talagang masasayang lang pera nila. Magbigay na lang ako ng isang example. Sa shop namin nagbebenta rin kami brand new, kung tutuusin mas malaki pa kikitain namin kung ioffer ko bumili na lang sila ng brand new, pero advise ko sa kanila. mas OK pang gawin yong radiator nila dahil OEM yon. linisin lang tubo, palitan lang ang top cover. babalik yong dating performance ng radiator tatagal din ng ilang taon, daig pa ang nabibiling replacement brand new, dahil mas kunti lang ang taon itatagal. Kung OEM naman, kung may mabilhan ha. halos 2 to 4x pa ang presyo sa nabibiling china made.

    Isa rin ako chief mech dito sa isang oilfield company pinagtatrabahuhan ko ngayon, dito sa middle east, Mas grabe init dito, maraming sasakyan inaasikaso namin, Mayroon ng 12 years na kaming truck, Lahat ng radiator nila, pina ooverhaul ko lang sa labas, hangang ngayon di pa ako nagpapalit ng brand new radiator. Kung sinabi ko sa company palitan na lang lahat ng radiator. baka wala sa oras tanggal na agad ako sa trabaho.

    Depende sa mga gumagawa, May mga hindi expert sa ganitong trabaho. Hindi basta basta hinang hinang lang. Marami na kaming nagawa sa shop namin. Hindi buwan ang binibilang kundi ilang taon bago bumalik sa shop namin. .

    Tandaan lagi may Pros and Cons

    Truck radiators are different. Tube wall thicknesses range from 0.15mm to 0.23mm and fin pitches range from 8FPI to 12 FPI max. Some trucks employ tanks that are bolted on as well. The removes the need to solder/weld tanks.

    Yung sa disyerto tuyo ang hangin at alikabok lang ang kalaban niyo as long as you use the correct coolant in the engine madaling linisin iyan.

    Those should last 15 years at least by design if properly maintained.

    OEM sub-systems are designed for reliability. If you have less faith in the brand new units you sell then you really aren't working your supply chain properly. A replacement radiator made to spec should last as long as your original unit.

    Typically given our environment replacement cycles come in at 10 years. Paying for that tank replacement, supposing you intend to keep your car longer, is a poor investment in reliability.

    There is a proper way of cleaning your radiator and diagnosing it for predictive failure. But if and when the radiator is due for replacement find a good one and bank on it.

    You can't mix metals wantonly and expect it to be trouble free. Pros and cons can't be relegated to anecdotal evidence.
