Filling radiator

[Lefty]

Just a quick stupid question
The vet radiator is installed on an incline, assuming I want to get 100% liquid in the radiator and no air how do you do it. There is always air in mine as the top tank is higher than the lowest part of the radiator cap, is the a secret or do you fill it up on a big hill?

Used to be a real pain for me to so I modified my thermostat housing, drilled and tapped a bleed screw to it so as to bleed all the air out of cooling system at the highest point.

Works like a treat

Some people add a new filling point to the top hose.  I have also seen thermostat covers with the fill cap mounted in the top.

thanks for the feeback, makes sense. my 24 has a plug on the upperr hose and works well. ill check out the hole in the thermostat housing, this may help.

cheers,

Is there an option to install a coolant overflow reservoir?

This way when the coolant heats and expands it goes into the reservoir taking the air with it, when it cools down and shrinks it draws only coolant from the reservoir ... provided the coolant hose is at the top of the rad.

That's what I have. Needed a few mm machined off its base to fit under the air cleaner.

Yes fit an expansion tank , BB vehicles have them

Ideally you want to eliminate all the air in the radiator. 

Rust forms at the air / liquid interface.

Many thanks,
Had a minor issue with heater hose last weekend which lead to the question. Have filled the car and it did self bleed, which was good, ow holding temperature well, bypassed the heater so the small hose outlet from the water pump goes straight into the thermostat housing (these are different diameters?). I don't think the vet needs any heating, any time of the year, the internal temperature always is warm.

Keen to install the hole to the thermostat or buy one pre done, in the near future.

Many thanks to all for responses.

I found this recently. I was looking for information on Evans waterless coolant after seing it on jay lenos garage. I'm concerned about summer temps and maintaining cooling. Interesting read.

I use a Nulon product
I find it good with aluminium radiator no over heating issues at all

Lefty,

The thing I've found with temps and corvette is that corvette aren't really designed for great air flows through the front end so you need to ensure all air is being drawn/ channelled  in through the radiator and not being wasted inefficiently though easier paths i.e all the other ares. Just me 2cents worths

Ok Jethro
Where did you cut and past that from
A bit to accurate for ranger at this time of night

What year is your vette

If you change fluids just make sure the system is flushed completely and I do mean completely.  Chemicals can do funny things to the ph when mixed.

Nah skl of hard knocks here Bobby trust me but you got me on accurate, I had to get Tracey to spell check me on inefficiently. your a fooker Tonto

True
Mix the wrong ones and sh_t hitting the fan comes to mind
Wrong combination u get corrosion pore cooling  flash boiling
Precipitation generating colloids in to the  solution causing blockages and water pump seal problems .
Flush and reflush
Any alumium in the system make Sure the coolant you use is compatible
And to make things difficult there are different aluminiums to cope with

Bfit, the vet is a 89 with a rhd conversion.

Sorry 79 with rhd conversion.

To fully fill radiator park car uphill with R/hand wheels up on gutter or jack it up & run engine
