Full set of cooling hoses as used on 1988+ E30 325i, 325is, 325iX. Can also be used as part of a conversion from early-to-late E30 cooling system.
This set can serve two purposes: to completely overhaul the cooling system hoses on 1988-1993 325i M20 models. It can also be used with other parts to update the cooling system from the 1985-1987 to 1988+ layout. This set focuses on the engine cooling hoses only. Heater/AC and other hoses are available separately.

*this hose is used for cars that do not have the additional heater thermostat on the firewall. Some cars have this (it was an update from BMW) while some do not, and some delete it altogether. There is a bypass line in the thermostat that returns coolant to the 743 hose. However, the 743 hose needs to be cut and a T installed to accept the bypass line. See Related Items below for a kit that covers this thermostat update.
Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age, and can eventually fail, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation. Replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.
New hose clamps are recommended, especially if you have mismatched clamps or older non-OEM clamps that can dig into the rubber (typically found at auto parts chain stores). We have new OEM stainless clamps available.
This package uses a mix of Genuine, OEM, and aftermarket brands. All parts follow the design of the originals very closely and use similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. All parts have a two year warranty.
