So here is some test results...
Went out this morning. Ambient temp 8/9degrees.
T= coolant temperature on housing
M= coolant temp preMatrix
BH= coolant temp at bottom rad hose
TH= coolant temp at top rad hose
After 4:30 steady driving:
T72. M69. BH60.7 TH20
7:15
T83 M83 BH70 TH77
10min. Partial load 0-60 (junction onto national)
T83 M83 BH24 TH81 (stat opened!!!)
30seconds later;
T80 M78 BH73 TH73
This is how it is general driving. It's fine (ish).
You do a pull of average length or accelerate as you would daily... It's fine. I think the stat has to work harder than it should and it creates more heat than I would expect..but it manages it.
18min
I then did some hard pulls... Repeatedly, braking, 3rd/4th... Braking, 4th pull, etc.
T88 M84.5 BH66 TH81 (''heat soak''?? Rad not able to bring temps down, temps continue to rise slowly)
T88 M85 BH70 TH83 (Oil at 110)
I pull in after a stretch of 60mph at these temps.
Stationary 19min into journey;
T87 M86 BH80.6 TH84.8
30sec later;
T89 M87 BH82.6 TH 85.5
30sec;
T90 M87.5 BH83.7 TH86.2
30sec;
T90 M88 BH84.5 TH86.6
30sec I put fans on;
T90 M87.6 BH74 TH83.5
Fan on 1min...
T84 M80 BH64 TH78
Fan off a minute later with temps at;
T81 M78.5 BH67 TH77
Cruise off at 60mph home..
T80 M78 BH69 TH71
Gentle 0-60 (junction onto A road)
T85 M83 BH50 TH80. (Stat has to open, rad cools it)
30min journey ends at home. Stationary.
T81 M80 BH53 TH77.7 (oil at 90)
