Coolant Schematic for Heater/ECT Sensor?
I'm using an Edlebrock water pump and performer intake with a heater/defroster, and looking for a location for the ECT sensor. I'm unsure of the direction of the coolant flow going to and from the heater/defroster core.

I guess I was thinking I would not want the sensor located after the coolant went thru the heater core, causing the temperature reading to be a bit colder, but it probably doesn't matter that much, eh? Just tee it in, on top of the intake manifold heater hose fitting, and call it good?

Burgs What intake are you running? You want to mount the sensor in the intake next to your coolant temp gauge probe. I have a Dove single plane intake, there are 2 holes in this manifold. You will get the best readings by keeping it near your thermostat housing. If not you could drill and tap a hole for the sensor in the water crossover by the thermostat . There should be a flat spot there. Rick Lake Ps some people mount them in the bottom of the overflow tank.

Thanks Rick. It's an Edelbrock Performer dual plane, and I am actually talking about the coolant temp probe, not a sensor. :o
There are three ports on the intake manifold. One is right behind the thermostat which is the one I will use for the heater and temp probe. There is another smaller one right behind the disributor, do you know what that might be? And then there is one, in one of the runners, for vacuum I presume, but wonder what it would be used for other than a vac gauge. |
Burgs The manifold you are talking about is a replacment for an engine in a street car with all the emissions holes in it. Some vacuum lines only work when the motor is at a operation temp like above 160F. This is why the extra holes for the valves that work off temp only. Some EGR valves don't work until a temp is reached. Coolant sensor and probe for the guage is right behind the thermostat. The temp gauge gets a workout, going from 180 to 160 in aheartbeat. I don't know what emissions you need for your car if any. I don't have my assembly manual for my car in front of me but I think 1 heater hose goes from the water pump and the other from the intake where you are at. ! is straight and the other in the manifold is a 90 degree one with a water control valve on it. It trickels the flow in the summer time and keeps the heat in the cockpit to a mininium. I have the heater blower in my car but is not hooked to the coolant. Rick Lake

I don't have any emission requirements here,... yet.
I bought my surge tank from Southern Auto, and they installed a disc with a hole in it, in place of the thermostat. They said they do this on allmost all of their motors, so I went along with it. I'll start out without hooking up the heater for now, but anticipate using it down the road to lengthen the season a bit. Thanks for the help! **) |
