Not essential, but you may find engine will idle fast, most throttle bodies with coolant flowing through them have a thermostat inside to raise idle when engine coolant temperature is low...

Blocking off heater won't harm anything, just run hose to bypass heater core...

Plugs are usually located in the grill area, so you don't have to open the hood. Are you sure you have a block heater

The thermostat "seals" the cool coolant giving up (rejecting) heat in the radiator & heater core from the hot coolant absorbing heat in the running engine "block".

When the coolant in the engine reaches a specific temperature (180 ~ 195 degrees) as determined by the value selected by manufacturer or when replaced, it opens and allows the hot coolant in the engine block to be pumped out to the radiatot & heater core for cooling and the cool coolant in the radiator / heater core is pumped into the engine block - replacing the hot coolant. The thermostat senses cool coolant in the engine block and seals shut until the temperature of the coolant in the engine block rises to 180 ~ 195 degrees again. This process continues over and over for as long as needed.

You should check to make sure that the coolant level in the reservoir / radiator is sufficient by checking when cold. Do NOT remove a radiator cap when it is hot! With the cap off, start the engine and add additional coolant as the engine warms up to normal operating temperature. If coolant levels are ok, the trouble could be related to the thermostat or possibly a faulty temperature sending switch. This means that the temperature of the coolant is fine - but the switch or sensor that converts the temperature to a voltage for the gauge on yur dashboard is the problem.

If the temperature is fluctuating up and down, you should have it fixed. Good luck!

The 06 Hyundai Elantra is a cheap car used and is worth aproximately $10,300 dollars. Data from KBB.com in 2009.

fuel used diagnostic

If its one, look on sides of motor (middle of block). You should see a cord start there.

Check that the heater core valve is opening when you turn the heater control on the console. It is between the engine and the firewall.

normally. .Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

(1) No need to know if engine block coolant drain plug was available. Once the water pump was removed, all engine block coolant was drained. (2) After removing the three engine mounting bracket bolts, I also removed the mount bracket from the the body and made enough room to replace the timing belt easier.

heater core could be clogged not allowing sufficient flow. feel both lines coming from heater core at firewall and see if they are same temp
