Abstract (en)
[origin: WO03060036A1] The invention relates to aqueous coolants with corrosion-inhibiting properties for the wet circuit, in particular for the running-in period of internal combustion engines, after which the coolant is drained off (engine running-in fluids), which comprise at least one ammonium salt of a monophthalimide of general formula (I), in which R<sp>l</sp> and R<sp>2</sp> independently or together = H, a linear, branched cyclic or acyclic C<sb>1</sb>-C<sb>20</sb> alkyl group and A<sp>+</sp> = an ammonium cation.
