5 Reasons Behind RAV4 Prime’s Heating Issues
Toyota RAV4 has several issues. RAV4 Prime heating issue is just one of those. Here’s a RAV4 user faced several backlash after buying it.
We’ve covered the 5 reasons behind RAV4 Prime’s heating problems and their solutions.
Reason 1 of 5: Thermostat
The thermostat is the first item to examine if your vehicle isn’t producing warm air. This is a relatively simple fix, and you might be capable of changing the RAV4 thermostat yourself. Thermostats degrade and might become stuck in an open or closed state.
As a result, the heater fails to function effectively.
In fact, this component is responsible for warming and cooling the antifreeze in your vehicle. A faulty thermostat can cause both overheating and overcooling of the vehicle. However, it is entirely dependent on how weathered it is.
Solution
Disconnect the thermostat and the two or three screws that keep the gooseneck in position. Wipe the motor, and the gooseneck seals afterward. Treat one surface with RTV sealant if you received a plain cover from the detail shop.
The thermostat and gasket should then be installed. The previous thermostat may have a rubber O-ring as opposed to a seal. In that case, grease the new one before inserting it. Replace the gooseneck and refill the antifreeze.
You could always take your car to a mechanic if you are not comfy fixing it yourself.
Toyota RAV4 thermostat maintenance costs approximately $300 and $345 on average. Labor costs are projected to range between $159 and $200, with parts costing between $141 and $145.
Reason 2 of 5: Coolant Issues
A heater core circulates lukewarm water from your cooling to the heating system. As air travels through, this base will increase the temperature, giving warmth to the vehicle. If your fan is circulating airflow but not getting warm, there are a few things to examine.
Your cooling system may have low fluid levels. It will not reheat if there is insufficient coolant to reach the heater core. Ensure the fluid levels in your radiators and external fuel tank are adequate.
You may have a leaking radiator or hose. Air bubbles in your cooling system might also be a source of concern. If the temperature of your engine changes while traveling, your engine may need to be “burped.” It must be completed for the air to be eliminated.
Solution
Simply remove the lid of the excess transparent tank. And pour in the antifreeze until it meets the whole level. After that, you have to reinstall the cap and tighten it, and you’re good to go.
Reason 3 of 5: Gunk and Grime
The presence of gunk and filth in the coolant system could lead your vehicle to overheat. The antifreeze in your car aids in controlling the heat.
As a result, this can have serious consequences. When silt builds up between the coolant and the heater core, it inhibits coolant flow.
The buildup of dirt in any part of the vehicle can lead to serious issues. Dirt getting stuck in the anti-lock braking sensors led to RAV4s losing traction control.
Solution
This is likewise a simple remedy that usually only requires a coolant system flush. In exceptional circumstances, the accumulation may necessitate tubing replacement.
Your mechanic will be able to assess the system for you and efficiently repair the coolant lines.
The average cost of flushing coolant from a radiator ranges between $100 and $200. The exact price may likely vary depending on where you go.
Reason 4 of 5: Heater Core Problems
Car heater issues are often related to heater core issues. These issues include-
- antifreeze may not be flowing correctly through the heater;
- airflow from the blower also isn’t accessing it; or,
- there is a blockage in the heater core’s tiny piping.
Heater cores are cooling system components that simulate tiny radiators. A heater core is constructed of brass or aluminum tubing. It transports hot antifreeze in and out and fans that dissipate the heat produced by the coolant.
A heater core is in charge of the temperature control and heating functions. Heater cores are often found in the back of panels. Suppose your automobile isn’t pushing excess heat into the interior and the coolant level is satisfactory.
In that case, you may have a heater core problem.
Solution
A novice may find it difficult to replace a car’s heater core. Because it can take up to 6 hours for two guys to work on it. That is why we usually advise consulting a specialist. However, if you want to do it yourself, watch this video:
To have your heater core repaired by an expert, you may have to count some cash. The total cost of components and labor may vary between $800 and $1,000. Labor expenses vary, so make reservations and get multiple quotes from repair firms.
If you repair the heater yourself, you will simply have to pay for a new heater core. It will cost you between $100 to $300.

Reason 5 of 5: Water Pump
Suppose you glance at your digital thermometer and notice the engine operating with more heat than usual. Yet, there is no hot air from the heater.
In that case, they may be experiencing water pump problems. Try shifting out of position and accelerating the engine a little.
Suppose the airflow begins suddenly becoming heated for a few seconds. In that case, this indicates a faulty water pump or low coolant. Also, if the conveyor belt connecting to the water pump breaks, it cannot turn as rapidly as it should.
Solution
Water pump repair is a complex procedure that should be performed by a specialist. Unless you have mechanical competence for that.
First, the car’s preexisting antifreeze is emptied. And any items that hinder accessibility, such as the timing chain or belt, are replaced.
The water pump and its associated components, such as hoses, are examined and, if necessary, upgraded.
The thermostat, radiator cap, and any valves or covers should be modified at this point. If the radiator spills or shows symptoms of wear, it should be replaced.
Finally, new antifreeze is injected, and the system is leak-tested. A test drive will establish that the new water pump is working correctly.
