need to replace the coolant reservoir bottle on my 1989 F350 any idea where I can buy one

 

I am assuming you have a 7.3L diesel engine. Overflow bottle is specific to a truck with a 7.3L
Part number was E7TZ8A080B. Engineering number E7TA8C045CE. That was replaced by F2TZ8A080B. Discontinued and nobody has any on the 3 parts locators I use.

 

BTW, it fit 1988/89 F250,350,SD only.

 

Jeg's... about $20 for one quart bottle. You choose the color.... the bracket is another $8 or so.

 

Parts store has generic bottles for around $17.
