B18 overheating 444-544 1959

posted by  someone claiming to be joaquin on  Sat Mar 17 10:39 CST 2007 [RELATED]

Hi. Some years ago my 121 (4 doors amazon, B18A engine) has the same behavior.

A local senior ex-volvo repairman drain the coolant, cut the cover(*) of the inspection hole located on the aft part of the head, and drill a hole on the end of the internal water distributor pipe (after it he put a new cover closing the inspection hole).

A low resolution photo of that inspection hole on my engine is available on http://www.geocities.com/yogui7/3/images/PIC0010.jpg

I don´t know if it is a standard repair procedure (the old man say this was on hot summers cities), but by now 200 F is the max temperature registered (I use a electrical temperature sensor).

Probably other members know a bit more about this procedure or remember it.

(*)this cover is named "Expander plug" 428677-1 in the Volvo P120 parts catalogue page 2a/4/3
