Hi
Sorry for the noob question, but could someone shed some light on the part located right in front of the driver seat (attached to the firewall) ?
There's a hose attached to it that isn't connected to anything

Thanks in advance !

 

Windshield wiper motor

The hose is probably for the washer fluid

 

Thanks a lot !

 

Its missing the second hose, going to the washer nozzles.

 

A bit of advice from one whose been there , seen that ;

See that white plastic semi transparent piece of tubing that has oil in it with some air bubbles in between the oil droplets ? That is how the aftermarket oil gauge in your car is measuring the oil pressure , that plastic line is connected to the full pressure of your engine's lubrication system and is delivering that pressure right into the back of the gauge . The problem is , that plastic tubing gets brittle from both heat and age and it breaks . When it breaks in the car it usually destroys your carpet by the time you've noticed the leak and are able to shut the engine off , and when it breaks under the hood it can spawn a nasty fire if it manages to spray the leaking oil just right (or just wrong , depending on how you view such things) onto a hot exhaust manifold . Fortunately there IS a solution , and that is to replace that cheap plastic crap with metal tubing , a kit for which is sold right on the same rack with the aftermarket gauges at the autoparts store . The oil gauges always come with a kit of the cheap plastic stuff so that's what everybody uses , right up till the first time they see the mess of having the plastic tubing break , then they end up installing the kit for the metal line .

Trust me on this one , it's best to be ahead of the curve and replace it before it rises up and bites ya in the butt .......

 

Thanks a lot for the warning, I'll make sure this is replaced before it causes any issue (not sure even why the previous owner added aftermarket gauges. Well spotted.
Back to the dangling hose, it seems the hoses are actually attached to a pump mounted on the side of the engine bay.
I believe at some point a repair to the original pump was needed and instead of fixing it, they installed a new pump on the side.
Does anyone have a photo of what a stock 1987 Iroc 5.7 should look like in this area ?
If I'm reading right the way it was setup changed in 1988+

 

Yep, looks like they didn't feel like removing/replacing the pump on the washer fluid reservoir and just threw a pump inline. I would just remove that one and do it the right way. But if you don't mind it, "If it ain't broke, don't fix it".

 

That's actually the correct pump that goes in the wiper assembly. There should be a clip that holds the pump in place. It's a simple plug in style.
