     Re:  Registration Statement on Form S-8 Relating to the
          Modine 401(k) Retirement Plan for Hourly Employees
          (f/k/a the Modine 401(k) Retirement Plan for Hourly
          Non-Union Employees)

Ladies and Gentlemen:

     I am providing this opinion in connection with the
Registration Statement on Form S-8 (the "Registration Statement")
of Modine Manufacturing Company (the "Company") relating to the
Modine 401(k) Retirement Plan for Hourly Employees (the "Plan").
The Plan is the survivor of the merger of the Modine 401(k)
Retirement Plan for Hourly Union Employees into the Modine 401(k)
Retirement Plan for Hourly Non-Union Employees with the surviving
plan being renamed the Modine 401(k) Retirement Plan for Hourly
Employees.  The Registration Statement is being filed for the
registration under the Securities Act of 1933, as amended (the
"Act"), of an indeterminate amount of interests in the Plan and
5,000 shares of Common Stock, $0.625 par value ("Common Stock"),
of the Company to be offered and sold to participants in the
Plan.  As indicated in Note 3 to the fee table in the
Registration Statement, the Registration Statement also covers
the remaining shares of Common Stock available under the
Company's earlier registration statements on Form S-8 with
respect to the merging plan and the surviving plan, which
available shares are being carried forward to the Registration
Statement in accordance with applicable SEC interpretations.  The
additional shares of Common Stock being registered by the
Registration Statement and the available shares of Common Stock
being carried forward to the Registration Statement from the
earlier registration statements are collectively referred to
herein as the "Shares."  Shares of Common Stock for the Plan may
be purchased by the trustee in market transactions or may be
authorized but unissued or treasury shares acquired directly from
the Company.

     I have examined:  (i) the Registration Statement; (ii) the
Company's Restated Articles of Incorporation and Restated Bylaws,
as amended to date; (iii) the Plan; (iv) the corporate
proceedings relating to the Plan and the authorization for the

issuance and/or sale of the Shares thereunder; and (v) such other
documents and records and such matters of law as I have deemed
necessary in order to render this opinion.

     On the basis of the foregoing, I advise you that, in my
opinion:

     (1)  The Company is a corporation duly incorporated and
validly existing under the laws of the State of Wisconsin.

     (2)  The Shares to be sold from time to time pursuant to the
Plan which are original issuance or treasury shares will, when
issued as and for the consideration contemplated by the Plan, be
validly issued, fully paid and nonassessable by the Company,
subject to the personal liability which may be imposed on
shareholders by Section 180.0622(2)(b) of the Wisconsin Business
Corporation Law, as judicially interpreted, for debts owing to
employees for services performed, but not exceeding six months
service in any one case.

     I consent to the filing of this opinion as an exhibit to the
Registration Statement.  In giving this consent, I do not admit
that I am an "expert" within the meaning of Section 11 of the
Act, or that I come within the category of persons whose consent
is required by Section 7 of the Act.

                              Very truly yours,

                              /s/ DEAN R. ZAKOS

                              Dean R Zakos
                              Vice President, General Counsel and
                              Secretary
