I got rid of my heater core and just wondering if i could just block the holes were the hoses come off or do i need to loop it so there is flow cirulating there
Don't just loop the hose. That's ok as a quick-fix for a blown hose or heater core, but not the way to go long-term. Coolant won't flow thru it like it did the heater. It could allow for a hot spot or air pocket too.
Cool I wasn't sure last 3 years it as been looped together after the heater core blow and it looked like @ss Thanks..
