Y60 GQ TB42S Coolant leak, heater elbow, service items DIY Maintenance

Speak to Anthony or Tinus on the hose kits, had my GQ done last year. Terrain taimer has all of the hoses and belts required

The water pump I got came with a gasket.

I think the thermostat housing just uses liquid gasket.

But it is actually very easy to make your own gaskets. Buy a sheet of gasket paper (called Valomoid or Flexoid) from your spares shop (it comes in various thicknesses, but 1mm should be fine for the intake gasket).

You cut this roughly to shape, then put the manifold in a vice (or hold it securely any way you like), and then use a small ball peen hammer to tap along the edges, effectively cutting the paper perfectly along the egde.

Like this: (although I prefer a much smaller hammer).

This doesn't work for all gaskets, but it's perfect for most.
Tappet cover and sump gaskets can be made from cork sheet (also available at spares shops). Head and exhaust gaskets must be bought.

Thanks, yes I thought this may be an idea if finding the gaskets is difficult.





So,

I managed to get all the heater hose fitting from Hose Fit, in Paarden Eiland, all of the brass fittings.
I am getting a new elbow made up, the one that was vrot, from Coolco in Montague Gardens.
Got some new hoses for the heater system, fuel lines and vacuum lines to the carb, so going to do that at the same time.

Going to hold off on the Thermostat and Waterpump for now, I'm broke

Should start putting it all back together tomorrow, thanks!

Evening all,

So I got the TB42 back together today,
Every heater hose changes with new hoses and stainless hose clamps, new fuel soft lines, a couple new vacuum hoses, all new heater fittings, new temperature sender. Lot of work

Started up the car and no leaks so far!!! Thankfully, hold thumbs after more testing.
Just need to bleed and cooling system and going to do 2 flushes on it.

My only question now is, once fitting the intake and carb back, as a unit, we didn’t do any fiddling with the carb, but on startup and idle the car is idling really rough, and if you rev the engine a bit it doesn’t smooth out with revs, it also seems to be over fuelling and running super rich.
Going to have a look in the morning, but initial thoughts are we set the idle adjustment screw wrong when putting the choke and throttle cable back? But would this cause tough idle, as well as when the engine is revving higher?

And advice, ideas or recommendations what to check would be appreciated, thanks
Just want to drive my Patrol!

I don't think so. The idling screw should only affect the idling circuit.

Three ideas to look at:
1) are the vacuum hoses in the correct order?
2) is the choke cable possibly too tight so that the choke is staying closed?
3) perhaps something got stuck between the needle and seat or the float's little arm got bent?

Changed the plugs on the car, and its running well now, just needs a little more carb tuning and then will be

No coolant leaks, so that seems to have all worked well!
Stoked!
Thanks for the help and recommendations!

I would speak to anthony and get a water level sensor for your motor . Om te meet is om te weet . Then you neva need to worry about overheating ever . You know when water is low

Hey guys,

I went to drain the radiator flush and coolant on the block of my TB42, that bolt below the exhaust manifold/headers, and when I opened it up, nothing came out?!
Anyone had this before?
I couldn't see in there, but I poked with a screw driver in the hole as I've seen on other cars that they can get blocked up, but it felt to me like it was completely closed like almost with a plate like its not suppose to be open?

Also my radiator doesn't have a drain plug, think it may be an aftermarket one, so just drain out the bottom hose, but obviously that doesn't get all the coolant out the block unfortunately......

Any comments on the above?

[Peter Connan]

Didn't comment before because I never faffed with that bolt. I just open the thermostat housing, take the bottom hose off and shove a hose pipe in there and run it for a few minutes. That will replace the old coolant with clean water, with which the anti-freeze will mix soon enough.
