ever since i have installed gas on my van a couple of weeks ago im not getting heat out of the heater.. i dont have much air flow cause of the xc grill does not line up with my modifyed heater cowling.. will make a new one out of fibreglass when marty teaches me how to glass..
its enough to take the chill of things in the freezing but i still get damn cold down here in vic..
my temp guage stays on blue cold also.. so i asume the thermostat is stuck open yeh? ive used a couple of different temp guages not just electrical, mechanical also to check its not the guages also..
so what i guess i look there first huh.. ive got holden 6's laying around in the front yard, grab a different thermostat and see if we see some results yeh?

Yeah I'd be checking the Thermstat! Does it take ages to warm up in the morn before you can get going?

Hi Ben. We have gas on Alien8 and the gas converter has water running through it, extra hoses coming off the motor to the converter. This is a silly question, :-[ and you probably have had a look, but have the heater hoses been diverted from the heater to the gas converter unit.
If the heater was working before the gas was installed, and the beddie temp hasn't changed, maybe just maybe the heater hoses now dont go where they used to. If everything was working correctly before the gas was installed it could be something to do with the installation. As I said a silly question :-[ :-[ if I have made a fool of myself trying to help then tough, its not the first time it wont be the last.

yeh i installed both the gas and the heater.. but no your not a fool shagginwagn.
it does take a little while to warm up eh..
ill attack the thermosat first
cheers

thermostat...

Hey ben, after you've checked the thermostat.....
I found that with the gas fitted all the hot went through the converter so the heater never warmed up.
The heater hoses came off the passenger side of head next to the thermostat housing.
I gave that to the converter only and took hoses to the heater from the drivers side of the engine (water pump inlet and thremostat outlet?)
I got the thermotsat housing and water pump housing from a pick-a-part as mine didn't have the hose fittings in place
Worked a treat ;) if it wasn't dark and rainy i'd try and get a photo for ya.

hey cheers for that worzel.. yeh i had that in mind when i was installing the gas.. i tryed to dirst the water to the heater more than the converter.. so it hat tee junction like about 100mm away from the thermostat housing.. yeh a pic of your setup would be rad. cheers

My Beddy runs the same plumbing scheme as this and I don't have any problems with it, if anything it can get too hot.

just something to check.
ive noticed that sometimes people hook the heater to the 2 conections just under the thermistat, but in actual fact 1 of the heater hoses needs connecting to the waterpump connector just above where the the bottom radiator hose fits on the waterpump otherwise no water will be pumped through the heater.
so if i were fitting LPG, i would have the water pumping first into the heater then to the gas converter then back into the thermistat housing.
ikm not saying this is your problem, but just an idea, otherwise your heater core might be blocked,
i got 2 heater cores reconditioned and they used commodore cores.

hey Warren, do you have the efi manifold on a six? I only ask cause I got a black efi 202 in the garage thats been sitting for a couple of years and I was considering doing a swap over with the 253 in the campa pending the arrival of monies for a v6 motor. haven't got a clue how to wire the efi 6 up so like most other projects it sits there taking up space in the garage. If you do have the efi 6 could I have a look at it?
-
Hey Eddy
Sorry mate, I don't have efi, mines a red motor.
It wouldnt be hard to do, you just need a wiring diagram from a holden of the era the motor is out of, and a beddy one and go from there.
Craig might be able to help with the holden one, and chris for the beddy.
I'd be happy to help out though.

Hi Ben, Had a look at the beddie, pipework. Its on the V8, but hoses should be the same, 2 hoses come off the thermostat housing, 1 to the heater the other to the Gas converter. 2 hoses come off the waterpump housing, 1 to the other side of the heater and the other to the gas converter. If that helps good, :) if not it just throws more confussion into the heater problem. :(
Hope it helps ;D
