The screws supplied with the LCA's are A4 stainless and are more than good enough for the job.

They are the correct size for the hole you drill and the alarms are calibrated to suit the supplied screw.

If you fit a screw of a differant size or material you will be inviting problems.

The screws/alarms only play up when somthing is added to the coolant (bar leaks/steel seal etc)

New coolant can also cause the screw to get coated. Some coolants lay down a protective layer on the inside of the whole cooling system when first added,,,,,this can cause problems for 2/3 weeks....after that a quick clean or a new screw (supplied by me) will fix it for good.

It is a small price to pay for the early warning it often provides.....see the testimonials on the shop home page (link below) some of the peeps who have posted on this topic have testimonals on that link.

Well over 3000 Bongos have alarms fitted.....very few problems reported and dozens of cases of the alarm warning of coolant loss long before any damage is done.

PM me your address and I will send you the correct replacement screws.
If your coolant is new and coating the screws then that would happen whatever screw you use (or if there is a additive in the coolant)......the problem will go away once the coolant has done it's "coating" thing..

There is nothing wrong with the screws provided.

That sounds about right to me - unless anyone is able to give a good reason why it should be otherwise.

If you ever suspect an issue with the cooling system, a simple self preservation test i do, is to lift the bonnet, place your hand down the left side of the air intake and (carefully, maybe hot!) squeeze the hose as it runs out of the top of the rad towards the engine, if the system is pressurised you can feel it in the pipe, if the pipe is 'squeezable' then they sytem isnt under pressure and shouldnt blast water out if you remove the cap!
