Yea, the water pressure gauge should be up in the yellow. Check the relieve valve on top of the radiator, they tend to not seat and weep also.

Relief valve gaskets were replaced. Water pressure wasn't hooked up, the wire was just coiled up as it didn't make sense at the time. I made an error there.

Alright so the water pressure gauge I've got is a bit different to the one we removed. it's an after market one, i got it early days before i knew any better.

So the issue is this is the end of it which goes in the hole in the radiator.



And this is the fitting



How does the brass olive get a watertight seal on the wire mesh? Do i need a different adapter to take it into the tank?

Or do i turf i and buy a cat one?

Thanks guys

Yea I believe a smaller ferrule and you have to have a threaded adapter into the tank. The Cat sending units had a plastic outer housing/coating that the ferrule would seal on.

Hi Team,
do not recall seeing a water pressure gauge with that style protective covering, they were usually a black nylon/plastic coating as said above.

From memory the ferrule either only seals on the tube itself or may seal over the Cat style protection layer in there as well as said by RomeKG--its been too long ago now.

Maybe with that woven style protection layer you have to change fittings so as to seal on the copper tube only.
That ferrule type fitting system is usually known as "petrol fittings"

Be aware that later on again these colour graduated gauges were done away with as they caused more problems than enough with operators mis-interpreting what they were telling them.

Hey fellas,

Correct. The broken cat one we pulled out of it, the olive sealed on the black plastic.

I might just block the holes off and remove the pressure gauge from the dash. The temp gauge I've got hasn't got the colour graduates, so it isn't really necessary anyway.

Went out today and the new fan belts have also worked a little loose, which is to be expected i suppose, and i put 20l of coolant in it which had escaped out the hole.

I'll put the old broken gauge back in to block the hole, tighten the belts and give it a bit of a workout to see how it goes. Engine temps are fine so I suppose it's oil flow or coolant flow. We did test the trans pressure ontop of the pump by your right foot when we had the transmission problem and it was within spec, but the lower end. Plugging this hole is the cheapest and easiest, maybe the lack of PSI in the cooling system is upsetting the flow somwhow.

I'll back into it Monday!

Well solved my transmission heat issue... looked at the right bloody guage! Now i have an engine overheating issue haha. Plugged the hole and now have coolant coming out the pressure relief valve, especially at higher rpm. New pressure relief parts coming and some of the cat coolant system flush so I'll get that done and see how it goes.

Been pushing some dirt around, you can certainly make a mess in a hurry. Getting the hang of it though.

Hi, Misterskill.
Good to see her doing what she was made to do - and LOVE those big clouds of the ubiqitous but politically incorrect black smoke.

Thanks for sharing.

Just my 0.02.

Now for the tricky part...



haha

I was just thinking that when I saw the pic with the blade down and coal rolling. I would imagine the plan is to have the old girl earn her keep as I'm sure shes a wee bit thirsty for just play! Nice work getting her going.

When shifting, try just bringing the rpms down to half rather than all the way down to idle, then pause a second in neutral before selecting a gear. This puts less load on the engine when trying to bring engine up to full load rpm. Better for converter and engine and saves fuel.
