Temp gauge spikes to hot


Sounds like you have air in the coolant system.. did you bleed the system after you replaced all this?.. did you replace the thermostat? You might add a comment about why you replaced these things .. and how you know they were failing>

Overheating


There may be air trapped in the cooling system. If no air bleed on the thermostat housing, or right beside it, start engine at cold, remove radiator cap, and let it idle until warmed up and the thermostat opens fully. When at operating temperature, shut off the car, check coolant level, and put the cap back on. See if that removes any trapped air.

1997 Honda CRV temperature gauge spikes to Hot

2004 grand am, 3.4 l. It starts out cold, coolant is full, and within 5 minutes ithe gauge spikes, it overflows out the over flow hose. It will spike and then come on down. No excessive heat comes out...


Within 5 min is fast, this could be a thermostant thats not opening but i may want to have a block test done. this test will tell you if exhaust is entering the cooling system and stopping the flow making the engine overheat as fast as it does. before replacing a thermostant i would make sure its not a headgasket problem first. this test is easy and not expensive to do, with a fluid and the tester tube connected to top of radiator the fkuid turns from blue to yellow if exhaust is entering the cooling system. this is the first thing to do and if it passes this test then i would replace the hermostant. another thing i have found with these engines is that the intake manifold gaskets leak. make sure the cooling system is full and has no air in the system. there will be a few thing s to check if it passes the block test, for example runnuing the engine and when it starts to heat up the bottom hose and the top hose should be close in temp and if the fans are turnning on when it get up in temp.but first is the test then the thermostant assuming the cooling system is full first.hope this is helpful good day.

Replaced thermostat, water continues to overheat and is expelled out the cap to the water reservoir. Water heat gauge show low heat then spikes to extreme high intermittently.


You have air pockets in the system. With the engine cold, remove the radiator cap. Then run the engine until the thermostat opens as you top off the radiator and keep an eye on the temperature gauge. If you think the car is going to overheat, replace the radiator cap, shut off the engine and wait 15 to 20 minutes to let the engine cool. Once the thermostat opens, lightly grab the upper radiator hose to feel for air pockets. You will feel the bubbles as they pass through the hose. Then have someone else rev the engine to 1800 - 2000 rpm and hold it there while you top off the radiator completely and then install and tighten the radiator cap. DO NOT DROP THE RPM BEFORE THE CAP IS SECURED OR YOU MAY BE SERIOUSLY BURNED!! Finally, let the engine run and monitor the temperature and road test. You may have to repeat the steps 2 or more times to remove all of the air but usually it will clear the first time.

It sounds like your thermostat is sticking. You can tell when it sticks when your temp gauge spikes high and your blower won't blow heat and when it finally opens your temp gauge goes back down and you have heat again.
