rear radiator flow questions...

[Screwy]

Putting the radiator in the back of the comp rig and running tube from the motor to the back...
just curious if the standard water pump in the 350 chev will be fine to keep water flow up or will i need to put something else in to pump the water around the system??

cheers

I can only tell you about mine.
4.2td ......water pump is fine for 4 wheeling but does over heat on the highway at 100 ks.
im using a crummydoor V8 radiator i think 2001 model

Ill read with interest other options as i need to change something to cool it

[Spartacus]

what sort of pipe can be used for a rear radiator?

mines a 2.8 daihatsu engine and ill be waiting to find out what goes on
before i add another pump

Whatever you have realy, stainless, copper, thin mild steel, anything really

im using treated exaust tube the same diametre as the hoses but i want to make sure the water pump can pump that far or i need something at the radiator end to pump it back....

my little one does it fine

yeh im not to sure about my pump either so im putting one of those inline electric pumps onto the line to give it that bit extra.

Might be work running a Davies,Craig electric pump Jeff. You can get regulators for them so you can infinatley vary the flow.

i run a davies craig 110 water pump au fans and radiator in the back never gets hot. takes ages to heat up has been a very good system

[batcho101]

i'm lookin into the exact same thing i'm runnin a 350 chev in my hilux and was goin to mount the radiator in the engine bay which meant i woudl of had to remove my original water pump and just run an electric one but to save hastles i'm just gonna run a rear mount radiator out of like a turbo diesel 80 series as i am pretty sure they are fairly large. it'll have twin 12inch davies craig fans and an exp80 davies craig booster pump runnin from the inlet side of the radiator.
the only thing i'm worried abotu is that the electric pump will be running flat out does anyone think that the water might cavatate due to also having the engine driven pump? i'll just be using mild steel tube aswell(sorry for the hijack)

[ads80]

mine runs constant with the mechanical and has no problems at all

[chunderlicious]

batcho, thoae davies craig fans have a running time of 4000 hours.... they do fail so keep a spare. just incase. im using mild steel aswell, so it doesnt bend if it gets hit underneath the car. i dont want to run an electric pump as its something else to fark up in the middle of nowhere with an expensive motor to consider.

[batcho101]

oh tru i didnt know the fans only had 4000hr life maybe i should go with an au setup then the davies craig are abit pricey to carry spares same with the water pump. at least witht eh water pump if it shits itself its a sealed unit so hopefully the engine pump will keep on pushing coolant through.

If the water is pumping through too quikly will it return to the engine hotter than it should or is this negligible?

[Screwy]

anyone got any pics or links to these pumps??
if there is one with a flow regulator that would prob be my choise....?

ive never seen these inline pumps before....

Ya Chev pump will push the water with no problems at all.

If your worried about it then fit an underdriven water pump pulley, the smaller pulley will increase the RPM of the pump, see a speedway parts supplier for one........
Also considerably cheaper and far more reliable than any other "aftermarket bolt on product' .... its a farken pulley so it WONT farkup.

Speedway cars generally run either exhaust tubeing or stainles zorst pipe as the "hoseing" for rear mounts then cover the pipe with heat wrap so they dont get a burn from the hot pipes.

Dont mount the top of the radiator tank lower than the highest water point in the motor ( radiator cap should be the higherst point )

Follow the simple rules and you'll be
