Sounds like you have either low coolant, due to not properly bleeding air from it when the coolant was changed, or the thermostat is not working, or possibly not right for the vehicle. (Honda's typically don't like aftermarket t-stats because they don't work as efficiently as the factory ones. And most are missing a bubble bleeder for air to pass through. (the little ball valve in most t-stats) You should also see if the cooling fans are stuck on all the time. They should cycle on and off fairly quickly as the switch calls for them. Air bleeding is critical as you have a large system with an aux. rear heater unit too. Even a relatively small air pocket trapped inside can wreak havoc on the operation of all related systems.

My 1996 honda accord doesnt heat up like it suppose to..unless its juss parked without any movement.. I drive it 2 miles away and it still doesnt heat up im concerned !! Any help ????


Thermostat stuck open?
Faulty temp sensor or gauge?
If heat comes out of the heater, engine thermostat is ok. That will isolate it to probably the temp sensor in the temp indication system (sensor & gauge).
The cooling system should be full. Temp sensors cannot read the engine temperature of steam or empty cooling galleries.

Honda Pilot 2003, low engine temperature, thermostat was replaced several times, still the engine temp is low.


use a termo laser to check temp of coolant at filler cap ,with cap off run vehicle till you have hot heat coming out of your heater then check with laser. if it reads above 140 then you know 2 things . either the therm sensor is going bad or the temp gauge is bad , make sure the radiator fans come on ,if they do and you have good heat then you have bad gauge.

That is a good temperature reading. If it ever gets up pas the three quarter mark, then you have a problem. Although most vehicles read at the half-way point on the temp. gauge. Hope this helps, James Booth PLEASE RATE THIS!!! :)

Check for low coolant, you might also have a sticking thermostat. Alot of fords get air pockets, make sure if it needs coolant to let it run for about 10-15 min with the radiator cap off.

In cold weather my heating doesn't blow hot air


When your engine thermostat has failed or is sticking open, the engine fluid isn't able to reach a temperature that lets your heater core get hot enough to produce worthwhile heat to blow into the passenger's compartment. It is also not good for your engine to run below design temperature.
If you have a dashboard temp gauge, if your thermostat is stuck open, that gauge will probably stay in the cold area.
I would think that that is the problem, and I would have the thermostat changed (not a very difficult or expensive job).
Hope this helps you.

Temp gauge bouncing up an down


That vehicle has two coolant temp sensors on it, both are on the passengers side of the end of the head, where the thermostat housing is. One has a two wire plug, this one tells your fans to come on the other is one single pin, this one is for your temp gauge. This sensor works off resistance, the higher the resistance the higher the gauge in the car goes. This sensor has probably grounded out and pegged your gauge in the car. Replace that sensor and you should be good to good, not too expensive either. Good luck.

97 saturn sl2 temp light flashing and low coolant light flashing what could be the problem ? coolant is full and the heat works.


If the temp gauge is reading normal, the lights are flashing, and the coolant level is full, the level sensor in the coolant bottle is the problem. I'm a service consultant for a Saturn dealer and I've run across this many times.
