Hiya, well, we've changed the water-pump, re-done the fan, changed
thermostat, new head gaskets & still it has a range of only 12 miles!! The
only other thing that comes to mind is a truely screwd rad. So, any further
suggestions will be accepted with open ears, but also, what is the most
straightforward engine change for road use, the lump we had is 2nd hand and
my well be going back to the previous owner shortly.

Cheers

Did you say in the first post that the rad was knackerd ?

That's your next port of call I would suggest.

If you need another 410 engine I've should habe one.

No, we thought it might be, but it has no external leaks, thing is we found
the head was quite gunked when replacing the gasket, could be there's been
rad weld used, could that clog it enough internally to cause the
overheating? How much would an engine be from you out of interest?

I went through this saga as well.

1. Electric Fan (not directly due to overheating, but because I wanted
one)
2. New Rad (Old rad had a cold spot when warm)
3. New thermstat (well why not, they are cheap_
4. New water pump (grasping at straws by now)
4. Second hand temp sender
5. New temp sender (really grasping at straws)

Then it finally dawned on me after much labour and expense. It was not
boiling over, the engine was not "pinging" or "ticking" with all the
heat. IT WAS NOT OVERHEATING!.

So an after market gauge from Gunsons (www.gunsons.co.uk) was fitted
(you need to order the metric adapters despite what they say) and my
"overheating" was gone.

Why, oh why wdidn't I stand back from the problem earlier.

I now know of 2 other people who had the gauge itself fail in a
similar fashion showing normal temperatures as hot.

Unfortunatly this little moto is a little more demonstrative, I'm not
talking temp guage up hi, I'm on about boiling hi pressure steam!

Rad weld is bad, have you tried flushing the rad out with a hose pipe ? Might
also be worth flusing the engine to make sure it's water ways are clear.

->overheating? How much would an engine be from you out of interest?

I'd have to check to see what I have, I've got 3 or 4 410 engines but I can't
rememeber if any of them are any good.

Was it the guage or the sender ? Jap senders don't work in Spanish Suzuki's

I've got a 413 engine & box you could buy if you fancy a bit of extra
power...1324cc's of mayhem....or something...

To fit a 1300 in a 410 you will need to move a engine mount.

We've got the gear and ability to do that, is it just the one?

Yea IIRC the nearside, you also depending on model, will need to modify the
gearbox mount, all ancillaries are also different so you'll need carb, statter
ect.

It was the gauge (I went through the Jap/Spanish sender saga with the motor factors)

I'm told that caustic soda is good for cleaning out radiators, so long
as you don't let it near the engine. One method is to remove top and
bottom hoses, close off the bottom with a rubber glove and tiewrap and
leave the solution for a couple of hours. Take all the necessary safety
precautions, it's evil stuff.

I see yo've replaced all the above, but have you tried the radiator cap as
well, if that's not causing the system to pressurise then you will get over
heating and steam escaping.

Just a thought, for a few quid before you change the rad.

Looks like we're going to try and replace the whole rad with a known working
one, the pressures off a little (scuse the pun) as we've just picked up a
cheap run around to do for the moment......
