Why has radiator started pissing out steam when it was idling on a cold morning?
thermostat stuck in the closed position, or blown head gasket, to check remove the raditor cap when the engine is cold and then start the engine if you see large bubbles coming out of the raditor the head gasket is bad
Where is the coolant drain plug on the engine block for an 02 Tacoma Prerunner?
The 2002 Tacoma engine block will have two coolant drain plugs on each side of the block. The coolant drain plugs will be near the front and the rear of the engine block.
No radiator cap once you drain the radiator how do you flush the cooling system?
If you do not have a radiator cap once you drain the radiator, you can use several options to flush the cooling system. You can easily do this by filling up the system with as much water as you can and then warm it up.Ê
Car radiator is shaking little bit its new car is it normal?
A radiator has rubber mounts that hold it in place. There should be no shaking from the radiator unless one of these mounts is defective or the bolt that holds it on is loose.
Is there any reason for a new radiator to leak other than faulty build?
possible sharp instrument stab from shipping past.
Low coolant? Radiator plugged or restricted? Cooling fan not working? Water pump not circulating coolant? Thermostat not opening? Cooling system airbound?
Why does your radiator leak only when the car is on?
When vehicle is running: Water pump is circulating coolant and cooling system pressure is building
How hot should a 2000 Chevy 1 ton dually 454 run?
The temperature gage in a 2000 Chevrolet 1 ton with a 454 should stay about in the middle of the temperature variation. It will probably run slightly hotter when towing.
What would cause the engine to overheat only sometimes 2006 suburban 5.3L?
When a vehicle randomly overheats, it is likely that the coolant level is low. Check the and fill the level to proper amount.
Where is the radiator cap to drain radiator on Nissan almera 1.4 P reg?
The radiator cap is located on the top of the radiator. The Nissan Almera has a radiator located under the hood.
Depends on the vehicle. I paid $400 for a new radiator for a '93 BMW wagon not including labor for the install.
Does the thermostat have anything to do with the radiator fan not working?
Yes,youll need a new thermostat if the fans not working.how else would your car keep cool...
The fan is probably an electric fan and is independent of the thermostat. The thermostat regulates the amount of water being allowed to run through the engine to maintain a constant temperature. The fan pulls the heat out of the water that flows though the radiator. Related but not connected.
There is a fan sensor that tells it when to come on and when to shut off. I don't know where it is, but it's there somewhere. Check that and check to see if there is power to the fan. Might be a blown fuse.
Have a small hole in radiator is it worth repairing?
It sure is. Leaking radiator fluid only causes the coolant system to de-pressurize and not effectively cooling all the internal working engine parts. As to repair costs, one needs to evaluate the cost of repairs vs replacing the radiator. If the car is older, then replacing the radiator might be the way to go.
How do you do a flow test on a car radiator?
This is a method shown to me by a radiator repairman years ago and has served me well. One can be easily baffled by test instrument companies but this simply tried and true method works for most cars (including full size passenger cars from the old school category). Adequate coolant flow through this type radiator core can be gauged very simply with the radiator in the car. Drain the coolant from the radiator (cool engine) then disconnect the bottom radiator hose from the radiator. Using clean and suitable water flowing through a 3/4 inch hose at 80 psi nominal/ 14-16 gallons per minute, insert the water hose into the fill neck of the radiator. The water should flow freely out the bottom of the radiator.
Radiators can be tested on a radiator test stand, these are expensive machines so not many shops have them or working ones at least. A find most shops that repair radiators just plug the bottom end ( cross flow turn it on its side) and fill the radiator with water and then unplug the bottom and watch the flow of water coming out. You really need to know the flow rate of a new radiator for your application as a base line. A big Detroit Diesel would be about 110 GPM (Gallons Per Minute) vs a pickup at about 55 GPM.How do you fix a plastic radiator leak?
By replacing the radiator. I've seen people use JB Plastic Weld and it only holds up for a few weeks.
Radiator fluid leaking inside the car to the floor and water levels go down very quickly?
there is a hole in the heater core, under the dash.
coolant is not circulating - open the heater and bleed the system ++ Another Answer ++ If the lower radiator hose is installed correctly and the hose clamp is tight and the "coolant comes almost all out ... like from the bottom of the engine", you may have a bad freeze plug that either rusted or popped out. You might want to get under the vehicle and inspect the bottom part of the engine. CAUTION: Be sure and block all wheels to keep vehicle from rolling over you.
sounds like thermostat is stuck closed, change thermostat
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
What is the function of a radiator fan relay?
The reason for any relay is to have lower power to the control circuit. If you tried to run the fan directly from the electronic control module there would be either insufficient power to run the fan or you would damage the ECM by drawing too much power and overheating it.
What are symptoms of Faulty radiator cap?
Overheating due to coolant going to the reservoir and not coming back to the radiator because of the bad cap.
Why is my 1994 Grand Am SE overheating after the thermostat was replaced and radiator flushed?
Low coolant?
System air bound?
Hoses collapsing under pressure?
Water pump not circulating coolant?
How do you stop a Home air conditioner radiator leaking?
if it,s in the furnace, look for a drain pan under the coils, there should be a drain hose comming from it. cold water grows a mold , the drain is pluged, use a pipe cleaner, or a thin bottle brush to open it, put a small amount of bleach in to the drain pan, check at an air conditiong place they sell a tablet that will inhibit mold groth, or at a pool supply buy some clorine tablets, small ones. place 1 or 2 in pan a month,
