Coolant is still running too cold?

1) replace the thermostat for a new Standard one.
also you may be surprised to find genuine should be a competitive price.
Don't use a hi flow thermostat unless you have a mods to suit, I tried that approach and it actually ran to hot.

Personally don't like the idea of just routing the coolant to converter then heater core then finally back to block.
Winter you will probably notice cab not as comfy as it should be.
Coolant re-entering the block will be to cold all year round.
If it was best practice to do it that way it would be done that way instead of using a tee pce.
There will be a whole host of reasons why the T is used and not plumbed without it.

Just replace the thermostat you'll find it's fixed and gauge will read in the middle again.
cheers

Thanx mate. I was considering it following another member's comment. I'm sure there's a reason for T(or preferably Y) pieces were used. I was open to the idea of re-routing it 'cos some of the LPG conversion work(electrical wiring work) on this vehicle was well below
standards. So, I was contemplating on the possibility of sloppiness by the installer with the coolant plumbing as well.
It's obviously too easy to plumb the coolant hoses to the LPG converter & heater core without T joints. So, there must be a reason for the extra work of using T pieces.
I've been trying to find some relevant information online on coolant plumbing specs on LPG, but haven't been able to so far.

BTW, I don't have to route the coolant first into the LPG converter. It can be into the heater core first and then into the LPG converter as well. By following the way the coolant valve work on the heater core

, I'm pretty sure now that shutting the coolant valve by sliding the dashboard heater controller to cool direction doesn't mean shutting the water flow then and there on the heater core.

It must be flowing back into the block(or LPG converter, depending on the plumbing priority)regardless of whether the hot coolant goes through the heater core or not. Having a valve that shuts the coolant flow in the heater core can't be a good thing. I think the way HVAC(particularly heater control valve) works in the RB30 Patrol is as in below diagram.

Thanx

P.S. I said "I'm pretty sure" in the writing in red above. But, actually I'm now fairly certain I was wrong about it. So, the statement in RED is INCORRECT.
The reasons are explained in the next post and more details are in the following posts.
