OK. You have a 1300 coupe heatr then.
The 1200 heater has the lower openings on the side. I think it may be posible to just swap the plastic housing and retain the efficient impeller.

Re: Removing S1 heater
I have a GRAF pump but the problem is the seal part no. 2189810. I would like to find the seal otherwise I may have to go for a complete pump made in Outer Mongolia as you said Huib.
I managed to get the nuts that were behind the impeller off. Most of them were very stuck indeed and would not turn. It needed a bolt to be welded onto them before they would come off - rather drastic but it did he job especially since most of the bolts sheared the bolt plug trying to get them off.
Did you say that the GRAF pump is an early one or a late one Huib? The impeller looks ok, a bit rusty but all the blades are all ok the bearing though is a goner.
I'll let you know what happens next I'm trying to find the seal if not then it will be a new pump for me. Tomorrow I take off the radiator & heater matrix.
