Leaky POSIV........ (How to use a Coolant Pressure Tester)

At the last SCCA Event Onething told me he smelt coolant but I didn't so we ran the event with few issues.

Today I changed the plugs on the car and took it for a spirited test drive. When I got home the aroma of coolant was noticeable. Looked around didn't see anything other than a quarter sized drip of coolant on the garage floor........

Figured I better figure this problem out quick before I blew a hose at speed and baked a motor. ::Drive2::

So off to Autozone to rent a Coolant Pressure Tester w/Adapters.

Let the car sit to cool off and then I tested the system. Here is what I found......

Read the instructions that come with the tester yadda yadda yadda......

First you need to open the hood and locate the Radiator!

Then open the cap (Remember I let the car sit a few hours so everything is cool)

Install the adapter that comes with the pressure gauge.

Next install the pressure unit and gauge!

Presure up the system with the air pump.

Uh oh the gauge is dropping so the system has a leak....

Looked around and saw I had coolant on the back side of the motor....

Little more searching and look what I found...... See the stream of coolant....

It is the damn little hose from the oil cooler to the back of the motor well at least I know the source of the leak.

Do you have to pull the engine for that?

No but it looks like it is going to be a PITA to replace....

I got a complete set from Rosenthal and changed them all at the same time.......except those two which are still in the plastic. I wonder why that is?

Because they are not leaking??? ::Fruity::

I replaced evey hose on the motor except for the one that is now leaking. Some how it never showed up when I was ordering all my bits and pieces. Didn't figure it would be a problem... :(

It did run for more than 10,000 miles and has been over a year since I installed the "cheater motor®" before this hose let go....

Well, you got good life out of it, so it was totally worth it! Mine was a snap to replace!

I have that hose laying in the garage, too difficult to replaced when I did the rest of the hoses. Lets hope it stays good for a good while longer......

Anyone got any tips??

Go ahead and change the Clutch/PP/TOB and rear main seal while you have the motor out.
CAS O-Ring, too!

If you are lucky enough, he may give you back a different car or put your car on weight reduction diet (taking parts off)!

Wow what a PITA!

Pulled the Vacuum line.
http://lh5.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0001.JPG
Disconected the wiring harness....
http://lh4.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0002.JPG
Now I can see the evil leaky hose (Screw driver on the hose)
http://lh5.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0003.JPG
Wrestles the hose clip loose and disco the hose....
http://lh3.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0005.JPG

Now on to the lower connection.....

Lower Connection easiest way I found to get to it was to pull the right front wheel and reach in through the wheel well.
http://lh6.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0006.JPG
Disco the clip and hose.
http://lh4.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0008.JPG
Fish the old hose out throw it on the garage floor and swear at it ::Rant:: !
http://lh6.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0007.JPG
Now reverse the entire process and install the shinny new parts.....

Now refill the system and pull out the old pressure tester...

Pressure the system up!
http://lh6.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0009.JPG

Wait about 20 minutes and see if the system holds pressure to make sure there are no more leaks. (Sorry about the glare)
http://lh3.ggpht.com/_ar4NWGG0rGY/TD...0/IMG_0010.JPG

It is holding pressure so I'm thinking it is fixed.......

The new clamps were a great plan since they are open with a safety clip on them you move them into position and pull the safety with a set of needle nose pliers and the clip is on!

Well, I can tell the needle didn't move, but there's no time stamp on the photos and I never heard you from my house ;)

I'll reserve final judgement until the next autocross.

I trust you'll carry a shallow dish and a box of Friskies to the next auto-x? Can't let any future coolant leaks get away... ;)
