I'm in the midst of a splitport swap and I have been tracing coolant hoses in my intake manifold.
On both the singleport and splitport intake manifolds, I see there's a hard pipe that runs from the front of the intake manifold, through the heater core, and back into the rear of the lower intake manifold.
Q: Since I don't have a heater core anymore, can I just cap off the front and rear ports of the intake manifold or for coolant flow reasons, do I need to run a hose from the front port to the back port?
Thanks in advance for your advice.
I believe you at least need the pipe for proper coolant circulation with or without the heater core plumed in, however, on a 24hrs of lemons car why not run bulk heater hoses to a remote heater core in the stock battery area with a small fan (off of a wrecked toyota truck transmission cooler for ex.), cut a hole similar to the air box hole for air to flow across it, sort of like an aftermarket trans cooler only it's basically an auxiliary radiator setup, I'd think that would be helpful for keeping it cool. Just a crazy thought though.
