Which one of these is right?
The upper one is for a 2nd gen 1.9L engine. The lower pict is for the 3rd gen. engines I believe. I think it can be used on a 2nd gen engine, except the 91-93 LX Escorts had a 3rd sensor mounted on the tubing going to the heater, so the transmission controller would know when the engine was warm and would begin shifting into 4th and doing torque converter lockup. The 94-96 Escorts only had two sensors on that length of tubing, as the function of the 3rd sensor was integrated with the one sensor having two wires to it.
A number of members have used the 3rd gen style thermostat housing with their 2nd gen Escorts. If they had an early 2nd gen. they would just short the two leads for the 3rd connector.
The top one is OEM for this vehicle.
It'll take some modification to use the (3rd-Gen) bottom one. Some use that because they don't trust the bypass valve in the OEM.
well im trying to replace my oem one. cuz i think it melted the plug since the heater NEVER gets warm.
Always disconnect both heater hoses and flush out the heater core both ways with a garden hose, to verify that the heater core is not restricted or plugged before condemning the thermo outlet.
The use of radiator stopleak products often kills the heaters in these cars.
Thanks Millball i will definently do that.
Yeah just a 97 ds heater hose.
If you move the sensors, will need to extend their wiring. (No crimping or capping - must solder using proper gauge.) Otherwise and if the new housing isn't provided with their own, are going to need junkyard (dummy) sensors just to plug the extra holes.
My wiring reached fine and there aren't any holes to plug as I put the sensors in the thermostat housing and removed the pipe the sensors were in.
Well I've read other cases where they've had to extend the wiring. The "hole" comment was if one opts to keep the original sensors in their place.
By the way, the perma-clamps on the OEM sensor mount are removable. Had sawed one of mine off to replace that section of hose after inadvertently damaging it.
You mean removable if you cut off the crimp with something like a Dremel, don't you?
That certainly works, but is overkill. Hacksawed in less than a minute.
