Heater Tube Modification

[techsan]

I am currently doing an engine swap on an 88 lx convt., and have removed all of the emissions equipment and heater/ac stuff. I am not sure what to do with the heater tube that runs along the lower intake manifold on the passenger side. I dont need to hook it up to the heater core any longer, and i have seen some people cut the tube and reroute the hoses. However, i dont know where/how to reroute these hoses. Anyone with experience in this matter that could tell me where to route the hoses would be greatly appreciated.

Thanks

well....the heater lines you are talking about just bolt onto the lower intake. and there is one that screws in on that same side. just cap off the outlets on the water pump and plug that hole and you should be good.

On EFI cars, the ECT sensor lives in the upper heater tube. Loop the upper & lower tubes together with a hose splice from Home Depot. This will make the water flow past the ECT sensor and give the computer the correct engine temperature.

Could you do the same idea as above and plug the water pump, etc. but plant the sensor in the intake right there? I'm sure as with anything else you'd need an adapter -- but it sounds ok in theory???

Sure, that would work. You may spend more time at Home Depot or the auto parts store than you would with a simple loop & a hose splicer.

My car still has a functuional EGR valve, so the loop & splice worked best for me. That way I had the EGR coolant lines intact & working.

I'm just thinking a little bit here -- other than the EGR cooling, the heater, and the sesnor right there -- is there any other reason to keep those lines? Any other holes that would need to be plugged? Again -- just thinking a little...
