I may be chasing a ghost...yeah, the venturi will not make or hold a vacuum (in this case...I have had success with it before on other occasions), but I just bit the bullet and filled the system with fresh coolant. I did try beforehand to use a different venturi fitting and re-plug the overflow...

This was an issue. My bottle has an overflow port (with just a piece of what looks like wire loom off that port) that comes off the bottom side of the filler cap area...right at the bottom, so the conventional seal adapters do not cover that well. My kit has a cone style, so I used that. I also...

I had no leaks before I did my repair (I had to pull the rear quick connect lines of the rear heater core in order to remove my rear evaporator for AC service..so there is a small chance that there is a leak there, but if it was, it would be a small leak...or a rear heater core from removing the...

2003 Suburban 1500 with rear AC. I touched base on this in another discussion, but now I am down to actually performing the task and am having a problem. Not sure if it a problem on the cooling system or the Venturi is not working with my partially drained system. First off, I have drained the...

This seems like a good approach. I have ordered some F-4 self fusing silicone tape. Is it O.K to bed the connection completely in di-electric grease? I always applied just enough to protect the metal contact points...just a smear on the male contacts and a dab over the receiving holes and a...

Got a set of LED Headlights and DRL/Signal lights for my 03 Suburban for my B-day. So excited to finally get some good night-time vision. The 2 headlight connections will be watertight, since they use the same waterproof light connection that was used on the factory lights. The daytime running...

You know originally I was going to ask that question, but then deleted that question after I saw the Schwaben instructions which clearly state. "NOTE: This tool is designed to refill the cooling system AFTER it has been drained" I would love to use this system to do top-offs, but not sure why...

I had to disconnect and drain my rear heater core to remove and change the expansion valve on my rear evaporator on my 03 Suburban. Heater core still looks good. I have drained about 1 gallon from the system. I have a venturi coolant tool: Schwaben Venturi Purge Tool I was hoping to avoid...

Orifice tube looks pretty clean compared to other pics I have seen. There is a little gunk at the top of the 1st ridge on one side as shown in the 3rd pic. Is it worth flushing condensor or evaporators? My main concern is how much oil to add if I only replace compressor and accumulator. I have...

I can't find any yellow one with a part number that fits my vehicle. 5.3 L Suburban 1500. I see multiple yellow orifice tube part numbers on Amazon (AC Delco) 15-30973 and 15-5759 and a few different Santech part numbers when I search without a vehicle filter. They all get kicked out when I...

@Chris142, Could you please confirm which orifice would be the best one for my conditions out of the 3 listed above?

Thanks, I guess a good place to start is to recover the existing freon and check the orifice tube.

I can see how this would happen. When replacing my actuators, the foam on the doors I could see was still in tact. Not new, but not deteriorated badly yet. When it blew cold, it blew really cold on 75 degree days. I don't think it was a blending issue, but I did have to replace my fresh air...

Funny you say this. I got a replacement AC clutch from an 05 truck in the junk yard (This did not work..separate post about this). But I noticed that donor vehicle had electric fans but the water pump still had the threaded nut for a conventional fan. The pump looked new, so I thought it was a...

I see the Yellow one on Amazon. The compatibility checker says it does not fit my 03 Suburban...although that may be because it was not the standard for that vehicle Yellow Orifice Tube RA has the original part listed by the dealer (1st design 13mm) which would be .512 1st Design 13mm Orifice...
