access holes

[longtops]

Hello All.Yesterday I took up the old floormat in the CORONET . Under the mat on passenger side there are 2 access holes,one is closer to the edge of the front seat halfway on the side of the hump the other is closer to the toe board.What are these for? One other question;under the hood on passenger side firewall there ars 2 what look to be hose connections where the heater hoses would go but there are no hoses attached .So I looked inside under the dash and there looks like sometype of copper thermostate thing,what the heck is it? THANKS FROM TN.

One hole in the floor should be for the master cylinder, unless they

located them in another place in 1950. The one on the side of the

hump probably is access to the transmission.....maybe to fill the fluid.

Probably are heater connections on the firewall.....

Per this so-so picture lifted from ebay-----one heater hose should come off the

water pump at front of the engine......the other one off the water connection

at the passenger rear corner of the motor. The car shown was a 1950 Wayfarer,

but should be the same as a Coronet.

Does the car have a fluid drive type trans? If so one hole should be an access to check fluid I do believe. On the cooper thermostat I think that is where a heater would be hooked up. hoses come in from engine through firewall into pass. side dash. I think this is what they are for. If I am wrong some one else will have more info.

One (forward most) is for access to the fluid coupling to check/add fluid and the other is for access to the governor/solenoid/interrupter switch on the M6 semi automatic transmission.

Heater core on a '50 Coronet would be on the front inner passenger side fenderwell with a cardboard tube ducting the hot air into the cabin.

Those heater hose connections, if that's what they are, aren't stock and there shouldn't be a thermostat for the heater under the dash...must be something added later...maybe windshield washer system?

Pat my dads 51 ply heater has that 2 copper tube deal for his heater. I believe it is a thermostat as you mentioned

yes the trans is a gyromatic.As far as the copper thing,there is no hoses attached to these connections.The actual heater hoses come from the core up beside the rad.And the heat works great.

The component under the dash on later heater systems is a thermostat if it has a capillary tube on it. Depends on what model you have I assume being a coronet or up model equipment spec its a model 500 heater. It should have 4 controls one for temp, one for quantity of fresh inlet air, one for blower speed, and one for defrost.

The flow of these heaters would be from the head, through the control valve, to the heat exchanger located in the ductwork near the radiator, and then retuning to the fitting on the water pump Fom a hose near the fire wall. This system should haace two fans one under the dash and one infornt of the radiator support.

Looks like your system was bypassed by a PO. If it works leave it alone, the thermostate would have contorlled the flow of coolant to the exchanger contorllig the temp of the put put air, With it bypassed you are essentially full on, and adjusting cabin temp witht he airflow ad fan speed.

OK greg g sounds like you have described this right.So your saying there is 2 blower motors on this setup? Some one here on another post said it sounded like the 500 series heater was what I had as to how the heat was coming from under and across the entire floor board.I'm sure someone has rerouted the hoses and if this is ok then I will leave it this way cause it WORKS!
