1, bibili ako ng surplus radiator with exhaust fan orig .ikakabit nalang..pero mukang alangan ako..kasi nakikita ko na mukang barado nadin sa dumi at medyo may kalawang nadin ung mga surplus na pinapakita nila..sa halagang 4.5k
2. bibili ako ng recondition radiator 2rows sa halagang 4,5k tanso na ung ibabaw ilalim radiator only...
3. bibili ako ng radiator 2rows ntaiwan made sa halagang 2.9k plastic ung ibabaw ,ilalim brandnew..radiator only
4. bibili ako ng radiator aluminum type 2rows brandnew..5k radiator only
i need your opinion to decide to buy of wich item.sana matulungan nyo po ako...

March 4th, 2013 03:40 PM #13Contemporary aluminum radiators handily equal that of conventional copper/brass radiators because of the homogenous material between the tube and fins where heat transfer occurs.
Though Aluminum has a lower thermal conductivity than copper, brass has a lower thermal conductivity than aluminum. Then there's the issue of solder, which also has a lower thermal conductivity than aluminum. This, on a metallurgical standpoint gives aluminum superiority over conventional copper-brass implementations.
However, Aluminum's bottlenecks come in, if and when heat dissipation demands are increased, as in the case of tuning, and when air flow becomes a constraint (drifting or uphill climbs).
Typical aluminum radiators have much thicker fins than its copper counterparts largely due to the manufacturing process and tensile strength.
What this means in turn, is that Alu radiators are size limited, i.e. the only way to increase performance is to increase the frontal area and thickness of the radiator. At this stage, aluminum radiators grow larger and will need to be filled with more coolant, and thus lose their weigh advantage to high performance copper-brass designs.
Thicker fins means you cannot increase fin density a lot because you will block airflow instead of using it to dissipate heat.
Copper-brass radiators, if designed astutely, begin to shine in this area as copper fins can be as thinner by as much as 72% thinner than aluminum fins. This provides high performance radiators with more usable surface area in the same or more compact package.

March 5th, 2013 01:09 AM #14this metallurgical knowledge is all very nice.. but how do we transform all these, into a choice of what radiator to put in our 1996 honda civic vti ?

If he intends to keep his vehicle until it no longer runs he's better off with a copper-brass radiator. If its simply about getting it going the aftermarket aluminum choices do a good enough job.
Unless his engine is no longer stock and he runs his vehicle competitively under harsh conditions, your run of the mill radiators would do.Last edited by EVO-V; March 5th, 2013 at 06:29 AM.

March 5th, 2013 02:33 PM #16mga sir update ko lang itong tread ko..
simula nung pinalitan ko ng brandnew radiator taiwan made..nag ok naman ung temp ko,,minsan bumababa pa nga ngayon ung temp level ko kapag malamig ung panahon...
ito lang po napansin ko..since hindi po ako muna naglagay ng coolant for observation..
kahapon sinilip ko ung radiator ko,,may nakita akong parang mga sementong maliliit na buo buo siya,ngayon nangangamba akong baka after a month eh tuluyan ng bumara ito sa bagong radiator ko..
binuksan ko ung radiator cap un nakita ko na nakabara sila sa mga butas..kumuha ako ng twiser at sinubukan kong kuhanin ..ung isa sa mga piraso nakuha ko naman siya singlaki ng butil ng mais (CORN) pero kapag piniga mo ng daliri mo ay malambot naman at nadudurog kaagad,,
medyo madami akong nakikita na nasa ibabaw,,,
na tatakot lang ako na baka after weeks or month eh barado na ung radiator ko..hindi naman yata ito nabubuksan or nalilinis dahil plastic seal ito..
may ibang ways po ba para matanggal ung mga parang buo buong parang semento sa radiator ko sayang naman kasi kung mababarahan kaagad eh kabagobago pa naman,,may nabibiling chemical po ba para matunaw ung mga parang cement na un..

Those sediments are residue from dried coolant, corrosion, and possibly other dissolved solids from the water.
You need to run the engine and filter those out before you install your new radiator. A stainless screen mesh on the inlet pipe of your radiator should filter this handily. Run your engine from 15-30 minutes and check on how much gunk you've managed to strain. Repeat until clear.
I'd be more worried about the smaller debris that fits through the tubes rather than the large ones you can see. Those build up like plaque.
If there's more of those inside your engine, it WILL clog your radiator and it WILL destroy it.

March 7th, 2013 08:20 AM #19Just to add on.
The brass tank replacement on aluminum cores, is just asking for trouble.
The incredible amount of misplaced trust people put on these shenanigans is dauntingly unnerving.
Galvanic corrosion will deposit gunk along your cooling loop's linings. This in turn will make it less efficient and prone to breakdowns.
The whole assertion of "matagal na namin ginagawa ito wala namang problema" is anecdotal at best. The very fact that people do not report adequately or understand how their engines are degrading, let alone the informality of this sector is really where the problem lies.

Choice I would have made as well.:nod:
2024 Innova Zenix 2.0 V CVT (non-HEV) vs Innova...
