Coolent buzzer in S7 FD
Hay guys,
Just finished swapping a motor into a 98 FD with a Power FC. Got the car running today but the coolent buzzer wont turn off. Coolent level is fine and been tripple checked. The car runs up to temp fine (watching with Datalogit on a laptop), all fans turn on at the right temp etc but the add coolent light and buzzer wont turn off.
Is there any reason for this? The motor is a S6 motor with S7 loom and PFC. The coolent level sensor is pluged, even tried to just ground it.
The buzzer doesnt come on straight after turn the car on but does about 5 -10 sec after the car has been started. Does the same when the ignition is turned on but not started after 5-10 sec or so.
Any ideas?

Yeah thats bleeding the coolent. There is definitly coolent in there and I dont think there are any bubles. The coolent sensor is on the front of the thermostat housing correct? I can see that this sensor is submerged in coolent.
How does this sensor work? Shuoldnt it stop if the wire is earthed? We have tried this and it makes no difference! Im thinking there is something wrong with the wireing. What I want to know if what does this buzzer need to work? Does it run via a relay etc?

You have an open circuit somewhere between the engine connector on into the dash. That coolant level sensor circuit has 5 connections on it's way to the dash. Two are inside the car and three are in the engine bay. Check your manual's electrical section, Z-44 for the path and inspect each connection.
The circuit works like this - Level sensor is covered by coolant and thus grounded. Once coolant drops below the sensor it triggers an open circuit and the alarm at the CPU. You have an open somewhere.
Covered time and time again....time and time again....

Check behind and below the P/S pump area. There is a BLACK Spade connector there that is part of the buzzer circuit. It needs to be connected for the buzzer to turn off if everything else is to Spec.
The Buzzer takes about 10 seconds to turn on anyways after the car is started. It is not "instantanious" It is quick, but not immediate. I just had this excat issue in 2 FD's that had their engines swapped

Hey guys, This engine swap was done on my car. We had a look for that spade connecter at the back but we dont seem to have anything that plugs into it on the loom as everything is all plugged in .

What does it plug into? something on the engine or part of the engine bay loom? The old car never used it and it worked fine.

I am going to call this sensor circuit the "Sasquatch Sensor wire" because nobody can find it.

Its a single wire and goes from the main emisions harness to the battery and starter harness it is the only wire that hooks to the other harness and it comes out of the back of the OMP plug on the emissions harness.
