I have a new radiator, water pump, heat sensor, thermostat and heater hoses. a heat probe indicates a lower engine temp than what the temp gauge indicates. Also, in heavy traffic, gauge needle goes to red and when in normal traffic flow, gauge needle goes back a little but still above normal. Additionally, there is no radiator o holes leak.
If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

Check water pump and make sure that its working. Should be circulating antifreeze in radiator and in engine. You can also check and the head gasket and make sure its NOT blown. Good luck and thanks for using FIX YA

If the hoses to and from the heater core are hot , and you say the heater core is hot , then the only answer is that the air duct that flows into or out of the heater core plenum ( housing ) is not opening.
Heater control on dash borad inoperative.
Not sure about 92 capri , some cars have a cable linkage , some work on vacume motors.
Try to find a haynes manual for your car , they will walk you through almost every step of anything you may ever want to do to your car.
You seem to know what you are doing , but I gotta ask ........the heater core you felt was up behind the dash inside the passenger compartment of the car right ?

Hi there,
Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.
The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.
So, other components which are likely to cause hot readings (in this order) are:
- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.
- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.
- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).
- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.
- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.
If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.
Cheers,
