jack the front end up and support it then remove one of the heater hoses
At 80 degrees air temp expect low side in the 20-40 range and high side 200-300
Engine Coolant is probably coming out of a small hole on the bottom of your water pump. This usually means your seals are gone in the pump and that the pump should be replaced. This happened to my '93 Jeep Grand Cherokee on I-40 near Knoxville about 3 years ago. NEW ADDITION: I am having the same problem with my 94 grand Cherokee today, we replaced the water pump and the problem still persists, there may be a hole in the radiator like mine.. just replace the radiator.. that's what im doing
On metric gauge 2.5 to 3 bar, about 40 to 45 psi. At least 15 psi, 25 psi would be better, 40 psi on a good engine.
Hey Mike==As a rule of thumb with the temp and blower speed set on high, it is great if the air comming out of the vents is 40 deg lower than the ambient temp. ie. If it is 100 deg outside the temp of the air should be 60 deg. It varies with humidity, makes and individual a/c's. GoodluckJoe
Try spraying them with WD-40 and let iot sit on there for a while. If that does not work try a 4 way lug wrench .
50 50 coolant is what i use- would suggest no more han a 60 40 mix.
It should be above freezing. Normally around 40-42 deg. F
25 to 40 lbs
No, this is perfectly acceptable.

40-45 depending on load
its called your heater core No it is called your heater control valve
First, stop driving it. Next determine why it is overheating. Check the radiator cap, and replace if necessary. Check the cooling fan and water pump for proper operation. If they are both good, then do a complete cooling system service. Drain the coolant, and flush the system with the heater control on hot. Replace the thermostat and install a 60/40 mix of the proper coolant and distilled water. This will allow for the water left in the system and give you a 50/50 mix. Bleed all air out of the system, and clean the exterior of the radiator fins.
Low coolant? Radiator probably needs flushing and/or replacing after 40 years. Bad thermostat? System airbound? Water pump not circulating coolant? Hoses collapsing? Bad radiator cap?
DO NOT TEST HOT COOLANT -- YOU COULD GET BADLY HURT, SINCE THE COOLING SYSTEM IS UNDER PRESSURE WHEN HOT! NEVER OPEN A HOT COOLING SYSTEM (radiator cap, expansion tank/coolant reservoir, hoses etc!) With a cold engine, use a "coolant tester," which is an inexpensive device that lets you sample your coolant and that allows you to determine the "specific gravity" of the coolant. The device may utilize a floating needle or colored balls that correlate to a scale showing the level of protection against freezing. You can get a coolant tester at any automotive supply shop. When mixing G12 coolant concentrate with water (ideally demineralized and distilled), the proper ratio is 1:1 for a VW or Audi operated in a moderate climate. The ratio may be changed between 40% coolant + 60% water (best protection against boiling) and 60% coolant + 40% water (best anti freeze protection).

It can take between 20 and 40 horsepower to turn the compressor that is the heart of an auto air conditioning. When you turn it on you cause the compressor to engage with it's belt and start compressing coolant. No matter how big of an engine you have you will always notice losing 20 to 40 horses.
