The engine may have a leaking head gasket, to eliminate this possibility a reputable auto repair shop will use a device that attaches to the radiator cap it has a blue fluid in it that will change to yellow if any combustion gas is present in the cooling system passages indicating a blown head gasket. Try the alumi seal product sometimes that works.

Drained radiator added prestone Radiator flush refilled and started overheating, drained radiator replaced thermostat and now I get no heat from heater,Radiator water is hot


disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

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,

First Steam then Water coming out of the overflow hose of the radiator reservoir. Is this a thermostat problem or Waterpump. When water is coming out the dash thermometer is approx half way. When I remove...


Your overflow hose is at the first tier after the seal on the radiator cap. The first thing I would check is the cap gasket, then make sure the cap is completely installed, push down hard and turn until it locks into position. If your water pump was bad, you would either be leaking water from the pump, or your car would be running hot. Usually, when you have steam/water coming out the overflow, if it is not a problem with the cap, then you are indeed running hot. If the thermostat is not opening or is stuck in the closed positiion, it will not cause your radiator to overflow, however if it is sticking closed and allowing your car to overheat then opening at a higher pressure, it could happen. Check the components in this order, gasket, cap installation, then thermostat, (you can replace the thermostat for about 10 dollars. Good luck

Overheating


If the cooling fans, water pump, radiator, and thermostat are all working properly and the engine is still overheating, I would take a look at something a little more simple, like a defective radiator cap. Try this inexpensive fix and see if it works. Sure hope this helps and good luck.

1997 cadillac eldorado running hot


Make sure you put in the correct temp thermostat. GM usually has 2. A low temp and a high temp. Most shops will give ya the high temp just because thats usually what the book calls for. you might want to try a low temp. Also, sometimes, when a car runs hot and everything has been repaired....well, almost everything......it might be the head gaskets. And those my friend are no easy task. But..somewhere to start. have your cooling system pressure tested. Only way to really know for sure. Oh..also make sure your fan is working!!!! You might have a faulty fan switch.

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00
