Question Water, idle, hose.

Hello lads.

Got a few more questions ha.
First is that my girlfriends PT has been idling high. It was at 2500 RPM. My dad had a look and found a hose that looked quite rotten with a hole in. it was on the top of the engine and pulling a vacuum. My dad split it and joined it. As mentioned it is visible form the top of the engine. What could this rubber pipe be? He managed to fit a bit of 12Ē copper tubing in it to join it and it was held in place with tie wraps. Once it was reconnected the idle dropped to about 1200RPM. Iíll be checking the ICV and the throttle position sensor to hopefully rectify this.

Also the car seems to be loosing coolant water; whilst Iím waiting for the new coolant to come I just have topped up what was in with de-ionized water. When I bought the car it had no visible level in but the temperature stayed fine, just caught it by the sounds of things. Saying and hoping itís not the head gasket. What parts are common to leak if any?
Since filling up the water itís dropped about 8-10mm and had a 3 or 4, 40 minute (37mile) drives.
Could this loss of water be air pockets etc?

If youíve read all of this thanks for your tie and sorry for waffling on.

Marty

On top of the radiator there's a chart with all the lines of the vacuum tubes which is the lines your talking about with the hole. Follow the chart and it ill tell you which exact hose you were working with.

Have you looked very carefully all around for a coolant leak? Down below the radiator cap is a plastic pipe that lead down to the thermostat. It has a tendency to leak. Look for signs of coolant. Is there any on the ground? If so try to trace where it's leaking from. If not, it may be a cracked head gasket.

Don't beat yourself up for asking for help. That's what we are all here for our selves. I needed help just recently. Saves us all a ton of money and most importantly, saves some pt's from certain death.

D-; if the idle is 1200 rpm after the engine warms up for a couple of minutes, it is too high. Should be 700-800 rpm. Change the pcv valve [$10], and check the hose for cracks/leaks.

2001/2002 PT's had egr valves which sometimes stick partway open, causing high idle.
