Re: strange cooling

OK so I got a pulley from CVF racing, it is a AMCL2WP. It fits some model(s) of AMC and Jeep. The pulley is just over 6 inches but the backset and pulley spacing is almost perfect, i just needed to space it out .060 to get the belts lined up and do a little grinding on the pump ribs. I was going to ...

Re: strange cooling

I just had a conversation with cvs racing. They have a ton of pulleys I just need to get the accurate measurements of the existing pulley. The measurements I have are estimates holding a tape in there with the pulley on the engine. Once I have the accurate measurements I will also check with march. ...

Re: strange cooling

I realize that the pulley does not need to be Pontiac just needs the right dimensions. Just thought about it. If I can find the right size pulley with a longer offset could I put a spacer behind it? Wonder what diameter that mopar pulley is? As near as I can tell trying to reach all the way down the...

Re: strange cooling

Yep, when I was putting this thing together the size of that pulley never even entered my mind. Been away from the business for too long, or maybe not long enough depending on your point of view. I do know that this Indian will probably be my last car, I do not think that I have another build in me....

Re: strange cooling

OK I have a NEW parallel tube condenser added to the new evaporator. I spent the last week modifying the radiator header, trying desperately to protect the new paint from the mig welder splatter and the grinder, so the evaporator is now behind the header about 3/4 inch in front of the radiator. I re...

Re: strange cooling

What year range of crown vic is the factory PF, I can ignore the trans cooler if I can make it fit. Let me rephrase that, I can make it fit but with how much surgery? For most of the installation I had the front sheet metal off doing the rust thing (the joys of an eastern car). I would rather not do...

Re: strange cooling

OK so I figured out the clutch issue at freeway speeds. The air is spinning the electric fan and it is generating enough current to back feed and keep the clutch engaged. Hows that for weird? So bottom line is that I need to isolate the fan on its own relay so it can't back feed. The other issue is ...

Re: strange cooling

So I now have a new evaporator, orifice and accumulator. It will frost the accumulator which it never did before. I have the gauges duct taped to the windshield and the pressures are strange to say the least. At surface street speeds, 30 to 45, it is cycling off at 12 psi and on at 42, high side at ...

Re: strange cooling

Working on hot systems is not an activity I indulge in often but for the orifice I used to clamp hoses off, pop the connection apart and slide in a new orifice. Did not do many but those spring connections come apart and go back together so easy and it saved so much time that what the heck. I have h...

Re: strange cooling

So I picked up a variable orifice for a Crown Vic Police cruiser at the Ford parts counter. This unit did come of a totaled low mileage police cruiser and because they spend considerable time idling they have the variable orifice. I clamped the pressure hose and manually triggered the clutch to suck...
