1970 heater water valve
« on: October 07, 2022, 08:55:11 PM »
 Looking for some help with a 1970 heater water valve placement on a 70 Cougar 428 car with A/C. I have 69s all over Mustangs and Cougars but no 70s. This one came as a roller with none this stuff there. If I could get a picture from someone. I have looked in assembly manual, but there is no real detail. Thanks in advance.
70 Eliminator, dearborn 428 CJ born 11/12/69, auto.

Looked at what I might have in pictures and came up with nothing that shows where the valve is attached on your specific application. Have Cleveland, Windsors and 6 cylinders but no CJ's If it helps the Clevelands were located at the passenger rear of the intake just attached to the heater hose connections that exited the passenger side heater nipple at firewall and attached to the solid metal tubes that were located on the top of the intake. Since the tube arrangement is similar on your engine I would guess that both of these are very similar for the location of the valve your asking about

Picture link to Mansfield Mustangs site and the tube for the 70 CJ

Not even close to being a great pair of unrestored, untouched original cars but hope this helps

1969 and 1970 428CJ with AC are the same. I posted the picture from a 1970 version of the MPC on the same queston you asked at the Classic Cougar forum. As Jeff says, very similar to the 351W / C versions.
1968 W code 427 Cougar XR-7 GTE Feb 23 Dearborn C6 / 3.50 open
1968 R code 428CJ Cougar XR-7 May 13 Dearborn C6 / 3.91 T - Lock
