I am building a car and I would like to have a clean simple engine bay. I would like to weld a couple of the coolant ports to simplify the engine and bay.

The car will be running a thermostat and heater core without valve. I would like to close the port on the intake, ports going to the iacv, and one of the ports on the thermostat housing. Basically I will be running a hose from the head to the heater core, then from the core to the one and only open port on the thermostat housing. Will this overheat the engine or cause problems?

 

all you need are the two main radiator hoses of course, and that short bypass hose that goes from the intake flange to the therm housing. you can plug everything else

 

Okay, so basically I can go from the intake to the heater core, then from the heater core back in to the thermostat housing.

 

That might cause an issue with your stat opening...best to just do the loop

 

Your going to have make sure you don't leave an air pocket. Just my. 02

 

I plugged everything on my car but I cut the center out of the t-stat.

 

we plan on doing this also I dont see what the problem would be... in fact all i see are benifits from not having to worry about hoses bursting for any dumb reason

 

I took the water pipe off the back of the engine and welded everything shut except oil cooler port and that bypass hose to T-stat housing, but I run no T-stat, heater core, IACV, etc. I also welded shut the coolant port going into the cylinder head as well.

I do get some overheating when the car spends a lot of time sitting still, but I usually just shut it off sitting in the staging lanes anyway. I do have a cheap *** dinky radiator and fan that doesnt help things anyway. It only sees track use anyway.

 

Well I am going to try it. I will drill a few holes in the thermostat. If it doesn't work out, then I can always go back.

 

mine is all welded shut. no problems here.
