Thread: pusher fan in front if radiator

I thought the sump was bigger on the holden engines always learning I have been thinking of going the larger oil cooler for the lr engine (2.6) as my oil temp is scary on hot days or long hills

Yes most (if not all) Holden Red and Grey Engines have 6 Imperial pint sumps where the Rover 6 cyl have 10 pint sumps.

An oil cooler with a small volume sump, means that you add additional volume in the pump circuit and it can keep the available oil as cool as possible. Remember that once oil is over heated it's capacity to lubricate breaks down significantly.

If you want a larger cooler, there is a 7 row oil cooler sued on the Britt Army landies and also an option for civilian Landies that do a lot of stationary PTO work. LR Series have them second hand.

I'm running without a radiator shroud at the moment, and I don't think I'm overheating, but it would be nice to be sure.

1. Is there a way to check water temperature while running, to compare it to what's showing on the gauge? Maybe take the top off the radiator and stick a thermometer in?

2. I'd like to do something about the cooling anyway, does anyone have any thoughts about whether I should fit a shroud or an electric fan?

Thanks, Peter

A fan draws it's air from the place with least resistance, if there is no shroud then the majority of air is drawn in from the sides and not through the radiator core. The only flow through the radiator core is because of the increased pressure in front of the radiator as the vehicle moves forward. Unfortunately when off road you are frequently not moving forward and so minimal cooling occurs. Once hot, you stay hot until you can get some highway speed to push the air through the radiator again.

I saw a message that was posted on Landrover's owner's club victoria and I thought that maybe I could pick all your brains.

I have a 1976 Landrover with a holden 173. It generallt sits on 200*F but can get up to 220*F on hot days (93*C to 110*C)...when crawling has got to 240*F (116*C). On the road I don't go above 3000rpm, usually about 2800 max. Head was done 5 years ago and had mechanic test since...all good.

I have put a small thermo fan in, had radiator reconditioned (original 6 cyl radiator)...I am chasing down a cowling so I can fit it...

have you any other ideas please?

I have heard that Holden engines get hot, but what is too hot?

A bloke down the road told me that his sits on 120*C all day everyday...now that sounds hot to me...

I used to have a S2a with an Isuzu and it sat between 200 and 230*F and I drove that for years, and the young blokes that bought it drove it for more...

anyhow, any help that you could provide would be appreciated.

Thanks

mine has a pusher fan in it out of a Citroen BX which i operate with a flick switch and relay (200tdi in England doesn't get warm enough to panic about), the majority of car fans have to endure serious amounts of water going thru them without failing so i'd take your repairers words with a pinch of salt regarding the electric fans...

here's a picture of mine getting a little damp



i was driving it home within the hour

Was the pusher fan able to push it back to the bank?
