Had the same problem. After new water pump, radiator, thermostat and lot of frustration it turned out to be the cap and the resovour bottle. Found out Jeep recalled original bottle because the plastic would get hot and then soften up which would break pressurized seal at the cap. Replace bottle and cap or try a good compression clamp around cap,(cheap fix,but hassel when adding anti-freeze).

Assuming you dont have a blown head gasket the most likely thing is a clogged radiator. Lee

Did you check if the fan starts up when the car has warmed up? The switch may have stopped working. Otherwise clean out the radiator and the outside. Make sure the thermostat is opening, even though it is new doesn't mean that it works. Start from cold and hold the top hose, it will get hot suddenly if it opens. Make sure all the hoses are clear and not collapsed inside.

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,

Overheating


You might wann replace the coolant, and also check the radiator fans, if they are working or not.

1990 4.2 Jeep Wrangler that is overheating


Is there any chance the thermostat got installed upside down? Flat end down into the engine is right. How hot does it get? Did you turn the heater on to circulate through it and get the air out of the heater core?
Thermostat usually open at 190 degrees, you may need a "candy thermometer" to double check the water temp in the rad. Get it in housewares. It's possible the thermostat is defective, I've seen that before. Hope this helps.

4.0 jeep overheating have replaced waterpump, thermasate, rator and cap, and lower hose. over heats of feeway. after 20 mins.


Does the gauge just show hot or is it loosing coolant? Could just be a bad gauge or a plugged radiator.

Overheating


there are three hoses leading to the water pump. the biggest one oviously goes to the thermostat housing, but the other two are much smaller 1 inch hoses, one of wich goes on the water pump and the other on the thermostat housing. if you follow the hoses one will connect to the upper part of the overflow for the radiator after hitting a T in the lines, that hose connects to the thermostat housing, and the other goes to the water pump its self.
