no, u should not hear anything when block heater is plugged in
When you first plug in the heater have the hood open and in a few seconds you should be able to hear the heater kicking in. It will make a sizzling noise.
First off, the block heater is an option, yours might not even have one. My 2002 Chevy had a block heater, and the chord was right next to the battery.
check for burned out glow plugs ANSWER 2 What year model do you have? Does it start if you plug in the block heater? There is a computer update from Ford that can be installed to improve cold starting problems. answer3 Most likely your truck has a block heater and you have to turn the ignition on to start the heater up. its that hissing- buzzing sound you hear whe you first turn the ignition on when its cold, that's why the motor emblem on the dashboard is red
you first have to have a block heater (frost plug heater) instaled on your car... they dont come that way from the factory
To hook up a heater hose to a 305 engine block, first locate the heater hose fittings on the engine, typically found near the intake manifold or water pump. Attach one end of the heater hose to the fitting on the engine block, ensuring a snug fit, and secure it with a hose clamp. Connect the other end of the hose to the heater core fitting in the firewall, again using a clamp for security. Make sure to check for leaks after the connection is complete.
If you are not getting heat out of the heater, there are only a few things that could be wrong. The first is low coolant. You can't get heat without coolant running through the heater. If it is low, sometimes it has to be bled of air bubbles. If both heater hose running to the heater are hot, you have circulation. If not the heater could be plugged or not getting the coolant to circulate. There is also a damper in the heater system to stop cold air from bypassing the heater and that needs to be checked.
depends on where and how you check it. If you are using a laser thermometer on the radiator, it should be about 210 degrees. I assume that you are asking because of poor heat.' if you have poor heating, first with the vehicle warm and heater on high check to see if both hoses going to the heater are hot if they are not, there is a problem with the heater core being plugged or the heater control valve not operating properly. If they are both hot, there is a cabin air filter in your car that is like a furnace filter and must be changed (could be plugged) or there may be a heater control door broken
The first possibility is the thermostat didn't work. To find this out, after the engine is warmed up u check the hoses going from the engine to the heater, they should be hot. if they are hot then the next reason would be a cable to the temp on the heater needs to be adjusted or the heater core is plugged inside or out.
The heater core is plugged. The thermostat is stuck closed. Antifreeze/coolant level is low. The water pump is not working properly. Check the cheapest things first. Check fluid levels. See if the fluid is circulating well. If okay, replace thermostat. If still cold replace heater core.
your heater core might be plugged(probable), or thermostat may not be opening all the way
First, check your rad level, possible heater core plugged, vent door problem, feel the hoses at the firewall where the heater core is, if they both feel hot it is not hte heater core, rev up the engine to 3,000 rpm... if it heats up it could be a bad water pump!
there isn't one that i know of. usually they are only in trucks to help them start in the winter if you are asking i presume you already have one that is not working.to repair it you must first acquire a new block heater from any reputable car parts vendor . then you must lift the front end of your car,place on jackstands,slide underneath and locate the old block heater. once you have done this ,empty antifreeze,slide underneath the car unscrew the old block heater,this may take a little prying and insert and tighten the new one making sure not to overtighten. now connect the new wire that came with the block heater and route it to the front of the vechicule preferably away from any pulleys belts or moving parts.refill with new antifreeze and check for leaks.if none you have completed the job and give yourself a big pat on the back.
