Alright, Need alittle help. Went turbo on the mach and had to do a custom coolant setup. 2'' lower stright rad hose to block, Put a rad filler neck/rad cap in between each port on the front of the heads(cut the stock crossover up to fit it), then have a inline t stat between the heads and the top of rad. Now my problem is it keeps pushing coolant out the over flow port on the filler neck and will over flow the catch can. T stat is in the right way. Got another filler neck thinkin the cap wasnt sealing to the filler neck and seem to do ok for a few trips but now is leaking again. T stat does open when you push it open by hand. Would there be any reason why you cant run a inline t stat in the upper hose on a mod motor? Also got another rad cap, this one is 18 psi when stock is 16. Hoped that would help but doesnt. Any ideas?
