Sender Unit Placement on 6.5lt Chevy v8 Diesal

Roachie will be along any minute now. If he doesn't know, no one does :-)

G'day Brian,
On mine, the oil pressure sender unit is mounted at the back of the valley, behind the intake. The water temp sender is just off to the side of it, on the passenger's side head.

I haven't fitted a oil pressure gauge, BUT, I did fit a warning buzzer to alert me to low oil pressure. All I did was to splice into the existing oil pressure wire, just above the pressure switch. The buzzer is mounted near the gear stick, but I have also fitted a momentary contact (OFF) switch, so I can isolate the buzzer while I glow the plugs and then for the few seconds it takes for the oil light to go off.

I do also have a oil temp gauge fitted........ but at the moment, I haven't fitted the sender unit in it's ideal position (the sump). Instead, I found a couple of threaded blind holes in the block. The one I used is just forward of the starter motor. I filled it with grease and screwed the VDO sender into it. The thread isn't exactly the same , but is good enough to hold it in place.

So, this gauge now reads the block temperature and closely mirrors the coolant temp as measured by the VDO gauge at the back of the head.

I have considered trying to get the centre of the sump plug drilled out and threaded to take the sender for the oil temp gauge, but can't be bothered at the moment. Another reason is that I have fitted a different type of sump plug with a tap arrangement (can't recall the name of it at the moment), so I'd have to get rid of that if I wanted to fit the sender in the original sump plug.

Cheers mate and hope it all goes well for you.

Hi Brian, I'm assuming you have fitted the engine yourself as I had mine done many years back by Brunswick Diesels who adapted all the instrumentation to the existing Troopy gauges. I also got a complimentary workshop manual on the chevy as part of the package. Cheers.

Brain, here are some photos, 2 oil pressure senders rear valley passenger side, water temp sender front passenger side head, a/cond overtemp cutout switch and water temp sender in the thermostat housing I made, murphy gauges with alarms. The original toyota senders hardly read due to the lower oil pressure and lower temp at the thermostat housing.My oil pressure is between 45 and 50 psi and water 180c. Hope you have an oil cooler fitted as these engines need it.Image Could Not Be FoundImage Could Not Be FoundImage Could Not Be FoundImage Could Not Be Found

we ran 6.5lts in our fleet of ambulances in rural ambulance victoria and they had external oil coolers standard equipment and never had oil issues ,every other sought of problem though ! put an external cooler on it an forget about it
