Water running temp
« on: April 08, 2019, 04:54:48 PM »
I have recently put a 1100cc head on a 998cc block with a 40 DCOE weber. After a lot of work and rebuilding, tuning etc the engine is running very well. When I am cruising at around 60kph the water temp sits at around 190 deg F ( 88 deg C ) but as soon as I run, for a time, at 100kph the temp climbs to around 220 deg F ( 104 deg C ). Once I return to 60 kph the temp comes nicely back down but I am concerned about the high temp if I go on a long journey. Is that too hot and if so how do I reduce the temp, alloy rad?? Electric fan ?? that sort of thing.

Hi Storm,

I have just been through this, have a read of the following.

http://www.spriteparts.com.au/tech/overheating.html

Also read the next article down, What to put in your radiator.

There are some good tech points on the above web page.

If you use coolant, dump it, flush the system and try Penrite 10/ Tenths Inhibitor. 

This will sound kind of weird, just like me i guess, when you have flushed the coolant out, put one good squirt of liquid hand soap in the radiator and go for a drive to circulate it.  Soap works like water wetter, it breaks the surface tension of the water.

FYI, Repco sell 71 degree thermostats, P.N. DT14C-BP  Dayco brand.

Cheers
Dave

Hi,
There has been some discussion recently about this that may be relevant.
Terry knows more, but if I understand it correctly, air flow through and over the passenger front wheel may counter the forced air through the radiator when at speed.
To counter it, people have put a plate in to extend the guard down. Have a look at the header picture above and look at the front of Vern’s multi coloured Moke to the right of the guy loitering in the blue shirt  :).

If you haven't already check your temperature gauge for accuracy.

Having read the replies it looks like the front of my Moke will require modification.



It was like this when I purchased it all I have done is put the led's on it, I think he wanted more of a Jeep look. Anyway it looks like I will have to get a piece of aluminium and fill in the front, somehow. The picture of Verns is a bit small to see.

A better photo of Vern's Moke for you Storm.

Sort of one extreme to the other when you look at yours...  :)
