P38 EAS Lean

Any chance of water ingress whilst the fan is running?

No chance of water getting that far unless the vehicle is submerged to that depth. The plastic mudguard liner is intact, the hole for air is drilled only through the steel inner mudguard, to align with the eas enclosure hole which I drilled beneath the cylinder head. So air is drawn from between the inner and outer mudguards.

I'm guessing you dont wade it then? Take it its switchable just in case like?

Supply is from the under bonnet switch panel via a very thin, sleeved wire so that the fan can operate independently of the EAS. This allows cooling after the car is switched off, really important here with so much heat soak under the bonnet. I don't go through deep water, the deepest flood water I have encountered was only up to about wheel centres and running quickly as most floodwaters do here. Deep enough for me. No, I don't have a switch to control the fan other than the thermal switch. Never had any moisture problems.

It doesn't matter what brand of car you have here, the sun damages inside and out unless it is parked in the shade or covered. I do both. Grey moulded dash mats are the go here, $50 au gets a really nice looking one and I have one in each car. Interior electronics, even beneath the seats, suffers because of the heat. Let's see if this flushes out some criticism.

I lived in Los Angeles for about 10 years, on and off, in place like the California high desert, Nevada, Arizona, New Mexico, etc dash mats are very common. It's not unusual to see 10-15 year old cars with dashboards rotted away to almost powder from sun damage. the killer is apparantly, using silicon spray on the dash to make it look like new as it tends to cook the plastic.

when i cam back to the UK i imported one of my cars, at 10 years old, every nut and bolt underneath was still like new and easy to remove. zero rust, just a little dust that brushes off. Indeed the heat can and often does make wiring brittle and electrical components can suffer, a parked car can see internat temperatures rising drastically. When i've operated aircraft into hot environments like the Sarhara, we've had to keep the APU running, A/C on, doors shut and cockpit window covers on as the heat rising started to pop c/b's and cook the electronics.

i'm wondering if the dust composition that you get in Oz , hanging around the amothpshere, can cause excessive weat on things like electronic tracks and potentiometers?

That would make sense. Mount it in the shock and it would be protected from the elements as well. Thought of the computer fan but rarely gets hot enough here to bother.

Most dust is uncommon on the east coast where I live, most people tend to avoid travel during the hotter summer weather when dust tends to be stirred. I avoid travel at any time in the interior because I find outback travel too uncomfortable due to intense heat, flies and lack of interesting countryside. My opinion. As far as effect on electronics, I have never heard of anything specific regarding dust damage. Rust is not unheard of but is not a problem with any modern car here. Hope that's an answer to your question. John

With the heat of the day adding to the underbonnet temperatures. it's not difficult to understand why the EAS gives so much grief in Australia. Proof is how well the Classic systems have survived, as long as water is kept out.
