Outer Limits 4x4 Board

Hi don't post much in this section but i have just fitted a 3.5 auto and rover transfer into my VITARA.
Now the Radiator is in the back for room reasons and i am having trouble getting the water to pump through.I have tried everything i can as far as making sure there is no air lock in the system.My only other thought is that as i have to modifie the Zook heater box to make the hoses fit i have just plugged the 2 pipes where they come out past the rear of the inlet manifold will this effect the water pump operation ????
In most cases i would have said no but am running out of options.

You mean you have just closed them off ? They dont recieve full pressure from the pump so that should be ok, are you having overheating issues?

yes gets hot idling in about 5-10 minutes

maybee you need an aftermarket pump thats what i was told when i had the radiator in the back of my lux

Yes I would think that an aftermarket pump is required.

Davis craig make an electric pump that would do the job.

How low is the radiator, is the water pump cavitating? Maybe mount the radiator a bit higher so that the header tank is above the pump & thermostat?

I very much doubt the 3.5 water pump is up to the job, did you replace it or have a look at it, it is more thank likely shagged anyway, go davies craig and you should be fine or replace the pump, ask the haultech guys they run rear rads on the rangie motors

We looked into this today.I have been trying to bleed it from the front nd having no luck so today we tried from the back and it worked a treat bled first time and runs cool as. We did pull the pump off and check it and it was like new.

Thanks every one for the help.

You may find that, over time, the standard water pump struggles moving that amount of water.....

Why would time make any difference? As long as the pump is in good condition it wont change.

Re-reading my post there I meant to say that it wouldn't be up to the job if it was half shagged like most of the rover v8s that are kick around for the cost of a carton of beer

I can remember being there when you guys setup the Ruggy and I didn't remember any aftermarket pumps having to be used - Chuck hadn't said that any of you needed it either. I do remember a crap load of air was stuck in there thought.

Thanks Tony for cleaing that up
