Thread: Engine Saver TDV6/TDV8

Hey mate,

That's weird timing.....

Ron B recently posted a thread on changing an RRS engine....body off chassis etc.

He'd stated that the motor had just been slightly cooked.

I just asked how that occured and how the owner was unaware.

I guess you've just alluded to the fact that the system doesn't warn you with sufficient time.

Is that the case?

Cheers,

Kev.

D3 already has one. A float sensor in the coolant tank. There have been istances of them becoming porous and dropping on their own.

In a catastrophic coolant loss that you do not hear/see/smell will not give any indication on the dash. As there is no coolant there is nothing to cause the temp sensor to rise. I had this happen in an old Datsun 200B hire car - I lost the bottom radiator hose, I didn't know and the first I knew was the smell of hot oil and a rattly engine - the temp gauge stayed on normal. The temp gauge tells you the temp of the coolant not the engine so if there is no coolant who knows what it is reading.

Carver - if there is a loss of coolant in the main system will coolant also drain out the filler/overflow bottle. Certainly in my 101 the level of coolant in the overflow bottle has no relationship to what is in the radiator - as a result my sensor is in the top radiator hose.

Cheers

My L322 has both the low coolant and overtemp alarms as standard,I would have thought the newer D4/Sport would be the same?. Pat

L322 3.6 tdv8 has not got any "low coolant" warning.
L322 3.0 td6 has "low cool,ant warning"
L322 td6 ems first cuts the AC when engine temp rises followed by cut to fuel to the engine making it almost impossible to cook an engine through slow coolant loss

I raised a similar question a few months back because of the need for a similar device on the D2.


Hopefully Gordon will see this thread and reply to it, but I am sure he said that the D3/D4 had appropriate alarms, even to the point of the ECU going into a form of limp mode.


Hopefully he will come on and correct me if my answer is wrong.


With the amount of hoses on the TDV6 I will buy 1 tomorrow if they don't have some form of warning.


Cheers Ean

D4 has low water warning.

Spoke to the engine saver guys and he said not to purchase one, as the D4 is well equipped.

Brett....

A low pressure alarm could be useful as long as it allowed for low pressure on startup. I had a low oil pressure monitor on my TD5 D2 that did just that. For an ignition cycle low pressure was OK until there was pressure, after which low pressure was an alarm condition that triggered stifling of the engine by closing the EGR inlet throttle valve and opening the EGR valve. However just an alarm would be of benefit.
