D2-55 Heat Exchanger

[moonlight_shadow]

Hi All,

I have just finished overhauling my heat exchanger on a volvo d2-55 and have a bit of an issue with the thermostat installation.

Parts diagram shows the thermostat seal goes in first, then the thermostat. Workshop manual shows the seal above the thermostat and just below the spacer sleeve.

It was installed originally with the seal first, but i noticed that this way the spacer sleeve protrudes a bit too much and is resulting in a lot of pressure on the housing cover.

Any one has some thoughts or experience to share about this please?

Thank you
Tyrone

Tyrone,
Page 73 of the workshop manual shows two types of D2-55s with different thermostat arrangements.
That manual is in the download section post #109
May shed some light on it.

Thanks. Yes, mine is the top one. Do you see how the seal is shown above the thermostat not below?

This is the dilemma.
