Has anyone had issues with engine bay heat shortening the life of their ARB air compressor? Has anyone mounted the compressor in the cab of their 70 Series?
Thanks

I know the small 24V ARB I have in place of the headlight squirt reservoir gets very hot after inflating 4 tires.
I feel most of that heat is self-generated. I have to have the bonnet open to operate the compressor anyway.
I have a rubber hose attached for the first 3 or 4 feet since it can withstand higher temps.
When done, I have to apply a damp paper towel to the air hose fittings near the compressor as they are too hot to touch.
I did not want another high amp device in the cab since I have too many new wires going through the firewall already.

My old BJ70 had the arb compressor mounted under the hood for around 15 years. I only used it for lockers, but it survived.
When I got my 74 I mounted the compressor in the cab. It only gets used for lockers as well, I have a Puma in that truck for inflation duties. Yes it gets your attention when it cycles, lol!

I know some of the Jeep guys place them under their seats but I would guess the carpet dampens some of the noise. I think it would sound like a swarm of woodpeckers if I tried that in my tin-can pickup.
I've had an ARB under the hood for around 18yrs now, no issues.

I’ve had 2 different setups under the hood and my current under the seat compressors. Both seemed to work just fine.
1 under the hood was even a hot 80 series 1fz I wheeled the crap out of. No issues.

Hello,
I hate to state the obvious, but compressing air increases temperature.
Most air compressors have a reciprocating piston in a cylinder that compresses the air. Like all pistons, it heats up from friction. Add compression heating to the stresses that said piston must endure. And this without oil squirters.
A well lubricated piston in an air compressor can last a lifetime.
In a couple of air compressors that I have had, I have put additional lubricant in the cylinder to extend the piston's service life.
I would say heat from both compression and overuse kills compressors, not engine heat.
As for mounting the compressor below one of the front seats, there is enough space in a 70 Series truck. However, in a 75/79 Series pick-up, the setup can be noisy because there is less room.
