Losing coollant cap when running but not running hot n did change to new cap
Check all the clamps first and make sure they are tight, but not overtight. Put a piece of cardboard under the engine compartment when car is off for the day. Next morning check to see if any drips on the cardboard and where they might be at in relation to the car.
SOURCE: Honda Removal of factory radio 1991 Accord lx
start by removing the console. there should be four screws that hold it in; two on each side; one in the front and one in the rear. you may have to take the gearshift knob of if the car is manual trans.then, remove the ash tray. there are two screws at the front of the ashtray receiver and one at the back.with the ashtray and slide removed, take the bezel off of the radio. there should be two screws behind or above the air outlet vents on top andn two screws in the under the center dividing rail. you may have to pop out the air outlets to get to the screws. there may also be a screw at the bottom of the bezel in the center.with the bezel removed the only thing that holds the radio in at that point is two screws that come up from underneath where the ashtray receiver was. take out those two screws and the radio should pull out from the front. Be sure to disconnect the antenna lead and the connector from the back of the radio before pulling on it too hard or you'll damage one or the other.hope that helps

When the car is completely cool,check the electric fan(s) for smooth rotation.
Clean/check/change the thermo sensor,contact and wire.

Excavate air pocket in coolant system / check for head gasket leak
This test will kill two birds with one stone.

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!
RAN THIS TEST IN A WELL VENTILATED AREA ONLY!
You will spill some coolant during this air pocket purge test.......BE
KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .
Top of the coolant reserve tank
Let it ran for 10-15 minutes.
Monitor for air pockets escaping from coolant reserve tank.
Small amount of bubbles is OK at 1-5 minute mark
After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.
If you do not see any in rush of bubbles then your thermostat may be
partially stuck or rusted badly inside the thermostat hosing.
Give the thermostat host few gentle taps.
If you see larger bubbles surfacing after 15 minutes then should do a
hydrocarbon (HC) dye test to test for potential head gasket leak.
Let engine cold down and top off coolant reserve tank.
Start monitor for coolant lost

A coolant flush is require every 2 years or 24,000 miles.
I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.
Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

SOURCE: 1990 honda accord temp gauge above hot limit.
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,

If the cooling fan shuts off after a few minutes with the ignition off, this is normal for most cars; it prevents hard starting in hot weather.
If it fails to shut off after a reasonable period, say 10 minutes or longer, the relay for the fan may be faulty.
If doesn't come on during running and the gauge is in the normal range, this is also normal.
If it doesn't come on when the engine temp is above normal, the sensor for operation has failed.
This is normally located on the bottom tank of the radiator and will have either one or two wires coming from it and most have a hex base for removal and installation.
These are fairly common failures.

The Main relay on your vehicle is defective. When the relay is operating while the engine is started and running, it gets hot. Add the hot weather to the relay and they break inside. The relay is located on the side firewall driverside above the left kick plate inside the car,and is secured with a 10mm hex cap screw (bolt). Replace this relay, and your vehicle should start.
