Hi Nigel, There are several types of Tstat housing used on the Raceline, some with a removable cap and others without. Raceline state that the unit is frequently used with no expansion tank and will require frequent checks for water level.
I also found on one of the Ford chat sites (passion for Ford?) that problems will be had if there is no hole in the thermostat to allow a bleed through prior to the stat opening. The hole needs to be large enough to allow water flow during warmup and small enough to ensure the heater gets sufficient flow. The article I read suggested about 2 – 3 mm hole. My system does have a removable cap and header tank but I did get too hot I drilled a 3mm hole in the thermostat which seemed to fix the problem although I have not used the car much since. I have checked the temp sensor I have fitted in the location along the side of the raceline. It has a 12mm thread which then goes into a T piece . The thread on the T piece which enters the Raceline is 5/8” OD. As to the thread type It may be NTP or BSP. A BSP fitting will only wind onto the T piece a couple of turns and a BSP male similarly only winds into the Raceline a turn or so before feeling tight. It may be a taper thread. So I think the answer to Robert’s sensor is that it is an AutoMega or similar with a 12 x 1.5mm thread Regards Ken Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10 ________________________________ From: quantumowners@googlegroups.com <quantumowners@googlegroups.com> on behalf of Nigel Plant <nigelp...@gmail.com> Sent: Friday, September 21, 2018 4:21:03 PM To: Quantum Owners Group Subject: RE: [Quantum Owners] Water Temp Sensor On the zetec Xtreme installation, there is no space for a temp sensor on old thermostat housing which is where the raceline bolts on as there is no clearance to the bulkhead. The intermediate position is used for a T piece connected to the water temp sensor and heater hose. Thus leaving the tstat housing for the cooling fan temp sensor. I will check mine later to see if can help. What about buying from Burton Power who sell Raceline or Raceline themselves. Out of interest have you checked yours? I have found on mine that the tstat housing is very high and if the water level is down ie expansion tsnk below the sensor the fan performance gets erratic or doesn't work. I assume due to an air lock. Regards Nigel -- -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
