Thanks Dennis,
So - a couple things for me to look at. When I purchased the original
digital oil temp gauge from Intellitronix - it came with a sender S8013.
At the time - I also purchased the GW sender 323 057 for the relief plug
port as I wasn't sure whether the sender I received from Intellitronix
would work. So I have the GW oil temp sender which matches what is
required for the VDO gauge. Now if you recall as part of my trouble
shooting for the digital gauge (and in turn did not work) - I swapped
sending units. So currently I have the wrong temp sending unit connected.
Easy enough to swap those out. The S8013 sender has a small nut that
connects the wire that I have attached a connecting ring to, whereas the
323 057 unit connects directly to a female connector.
Coolant temp seemed to be within range - as best as I could tell. Low and
high speed fans were cycling when temps were climbing to just above the
warning light. This would occur in slow bumper to bumper traffic over a
period of time. One thing I noticed was that the high oil temp gauge did
not indicate a higher reading necessarily when the second stage radiator
fan kicked in. Nor did the high speed fan kick in when climbing the pass
where I had a reading of 270F. Temp gauge was below the warning light
level.
I will reduce the amount of oil - as it is at the max level. I go by 4.5
litres with filter change - 4 litres without filter change. This will go
hand in hand with swapping out the sender.
Hopefully these little changes will make a difference - if not I will be
looking for a secondary oil cooler. BTW - Is there anything that the stock
oil cooler may need inspected or replaced?
Thanks again.
