Oscar of Markoz 160 Posted October 18, 2017 Question. I have an alloy radiator which will be going into a TF cortina. Intercooler infront of it. The rad is a 2 core. I'll be running a thermo and electric water pump. Currently the radiator is just in 1 end tank flow across and out the other. Will this be sufficient or should I make some dividers in the end tanks so that the water has to make 2 trips across the core before exiting out? Share this post Link to post Share on other sites
Drew442 67 Posted October 18, 2017 I'd probably only do it if you have the ability to do it yourself or have a mate who can do it. If you have to send it out then the expense probably isn't worth it.Multi pass is definitely more efficient.Sent from my MI 5 using Tapatalk Share this post Link to post Share on other sites
Oscar of Markoz 160 Posted October 18, 2017 I can do it myself. I have removed the end tanks as I need to shorten the rad by a few mm's to fit. So I thought maybe I should do it while I'm at. Just wanted to see if I needed to do it or not. If I don't need to then I can continue with my work, if I do then I have to order some 3mm alloy sheet and start cutting etc. Share this post Link to post Share on other sites
