Heater tube arrangements for a 650 engine i a Fiat 500

I've put the 500 version of the thermostat housing on the 650 engine. The direction that the hot-air outlet points is no problem despite the starter-motor appearing to be in the line of it.
I've adapted the metal transfer tube from the 500 tofit by drilling and filing a slot for the starter-cable stop and bashing it out of shape. But the problem I'm having is that despite that, there is not quite enough clearance between the tube and the starter to allow me to fully slip on the rubber outlet pipe, so the clip doesn't really grip.

It looks like the alternative steel transfer-tube available for the 126 and "R" doesn't have any different geometry to the 500 version, just the dent to clear the starter and the hole for the nylon stop.
Some of you must already have achieved this and I would appreciate knowing how.

Which end are you having problems with? The left hand by the dent? I've got a 126 one in the garage. I can measure it for you if you need any comparisons? Let me go and get it and I'll post a picture.

Here you go fresh off the press! Just noticed as well there are two little metal tabs to the right of the hole where the starter cable stop goes which I assume you tuck the cable behind?

Re: Heater tube arrangements for a 650 engine i a Fiat 500

Thank you for that. I think I've worked out that the position of this item under the floor may be slightly different on a 126. Temporarily I have removed the screw nearest the engine and will re-drill in a new position that takes it away from the starter just enough. I was going to use chassis wiring clips to emulate those tabs but the cable l
simply found its own route and the surplus from one of the hose clips on the final flexi-pipe wrapped round and secures it. At least it's sorted sufficient to let me pull the starter. All sorts of factors may have contributed but the starter action is more positive now.

The dent is for the solenoid isn't it?

You could have gone all sophisticated like what I am!!!!! Well the plan is I should say and ditch the starter cable and start it all modern with a key!!!!!

I thought it would have been right up your street seeing you have turned into a modster

Re: Heater tube arrangements for a 650 engine i a Fiat 500

I actually traded in my solenoid operated one for a pull-starter. I don't mind adding things but I won't take the away.

Agreed, like you, in a bizarre way I personally prefer the hand starter. Part of the cars character. Glad you got the cable sorted in the end.

Cheers, Steve

Re: Heater tube arrangements for a 650 engine in a Fiat 500

The flexible rubber tube from the thermostat cowling was barely long enough with the new engine, which was odd as I have used a 500-type cowling and it was OK before. After a couple of hundred miles it has already been forced off at one end. In the course of digging through my many boxes of old spares I found what I presume is an original flexi-tube; it's quite a bit longer.
MAL_4807 by Peter Thompson, on Flickr
So with that problem sorted I have encountered another one; despite having bashed the metal heater tube to clear the starter, when the metal clip is fitted it all but touches the starter terminal. Obviously this is a lethal situation to have and the tight clearances are almost certainly why the starter was originally fitted at the top on the 500. Another less serious problem is that the heater tube is very close to the suspension spring as I attempt to move it away from the starter. I have also had to shorten the exhaust shield plate by a significant amount.
I wll get hold of a 126-type heater tube but I suspect that I will have to do some more modification to that by way of removing and re-welding the mounting brackets.
I wonder how straightforward this proces of modification has been for other people.

I notice that VdL have started selling the correct exhaust deflector for a 500R.

This would be much better modification to my F than the current deformed shield which I think vibrates at some speeds.
So I'm going to do the job properly and fit the proper 126/R thermostat cowling and buy the proper heater tube:

So my question is; which flexible tube will I need? There are two types of this listed as 19mm and 21mm.

Re: Heater tube arrangements for a 650 engine i a Fiat 500

I think you mean 19 or 21 cm? I was trying to get my head around what measurement you asking about, so looked on their page. I would go 21cm as they have another one on there which says "similar to original 21cm". If you bought the shorter one and it is too short you are knackered. With the 21cm one at least you can loose the extra length in the concertinas or trim it.
Thanks fiat500 thanked for this post
