Hey guys, Im looking at making a closed water cooling loop for under $100. Right now I have found this pump, do you think it will work, in terms of pressure and gph? I will have a reservoir maybe 1.5 ft by 1 ft by 8in. http://www.amazon.com/EcoPlus-Submersible-Pump-396/dp/B0018X2XT4/ref=pd_rhf_p_t_2. Do you think I will work? I will be using a 77 pontiac bonneville heater core, for the radiator. How will this work compared to something like the black ice? http://www.oreillyauto.com/site/c/detail/MHT0/398219.oap?ck=Search_heater+core_02709_1246250_3576&keyword=heater+core&pt=02709&ppt=C0331. I have heard many people use these. Another problem is that the fittings on this is 5/8 and 3/4, when i have 1/2" tubes. I dont think the 5/8 will be a problem, but the 3/4 will. I dont have a soldering torch, so what do I do?
