off topic, Webasto Vs.Espar

[Cornbinder89]

I don't use, nor do I give much stock in charts. Pressure reading tell the story (as long as the gauges are accurate) You want the high side to condense...

[Cornbinder89]

See my comment above. I still think you have a condenser problem. Spray the front of the car with a hose and sprayer and watch the temps and pressures....

102 PSI static says the temp is between 90 to 95 degs. so I am a bit confused here, Also How are you measuring temp, Laser (IR thermometer?) I don't...

[Cornbinder89]

Does it have a pilot operated Absolute valve?...

[Cornbinder89]

As far as thermostatic switches Heavyer GM's use a MEI 1331 which is a 24" capillary tube switch fixed 34-38 deg or about a 5 deg off to on temp...

[Cornbinder89]

From what I can remember from back then, they had a VIR (valves in receiver) which has a large accumulator looking thing, It took a replaceable desiccant...

Does anyone know if the 7 day timers for Webasto and Espar heaters are interchangeable? They are both made by Hella and look identical except for the...

[Cornbinder89]

I think he has that and a pilot light, he said he added that when he towed a lot with the Blazer

[Cornbinder89]

So... is this an orifice tube system? I would have thought it was a VIR or Tx system with a frost switch, Somewhere I have a '73 Chevy truck manual but...

[Cornbinder89]

Also, cooler while driving also points to a condenser (or air flow over the condenser) problem. Try misting the condenser with water and see if the high...

[Cornbinder89]

250 PSI= 155 deg which is dang hot for a condensing temp with the outside temp of only 80, what is the temp at the outlet of the condenser? I'm thinking...

[Cornbinder89]

I have zero experience with that or most other recovery machines, so can't answer. I pump my used stuff into a tank but either use small cans or a scale...

[Cornbinder89]

I wouldn't jump to that conclusion just yet. 2 lbs is low for a big truck system, but this is a different sort of truck than an on road tractor. ( Think...

[Cornbinder89]

Look, I have no dog in the fight, I am giving you my best, thought out opinion. I have designed and built my own complete systems, and the A/C in my cabover...

[Cornbinder89]

The thing I keep coming back too, is the icing of the evaporator. If the evaporator can get cold enough to "trip" the frost switch, it is cooling...

[Cornbinder89]

My guess is that the Dodge has a CCOT system so cycling would be normal under low heat load. Line length: it would be hard to change length enough to...

[Cornbinder89]

Methyl-chloride is used with centrifugal compressors with low high side pressure (IIRC he said 50 psi in that write-up) there are modern replacements,...

[Cornbinder89]

Ammonia can be used in a "conventional" compressor type systems but must use steel as brass and copper can corrode when exposed to it. It is...

I lived in apt in Chicago that still had an access door from the back stairs for the Ice Man to deliver right into the ice box. Talked to some oldtimer...
