06 pt cruiser turbo replaced radiator test drove and coolant was leaking found black wire to fan not connected radiator won't fill after 8oz it leaks out

So you drove the vehicle with the power to the fan and it overheated and was discharging coolant?

After you have drained coolant and then refilled, you have to 'burp' the system to remove airlocks. There are videos if you Google 'burping vehicle radiator'. Basically you run the vehicle from cold with the radiator cap off and add coolant as the level drops. When the thermostat opens the level will rise and fall. There is a gadget that you can fix to the top of the radiator cap that you fill and the level is maintained. You can help the process by squeezing the lower and upper radiator hoses. The system must be full of coolant with no air. Then you turn the engine off, top up one last time, replace the cap and then top up the reservoir.

1994 Toyota Camry LE V6 Overheating, Steaming Engine--Blown Head Gasket??

It is best to be systematic about this. It could be either the water loss or the overheating which is the basic cause, either one could come first.

- there is a test for combustion gases in the water jacket, from a blown head gasket. This will very quickly cause overheating, and the excess pressure will blow the water out the overflow reservoir. If the car has already overheated and died, this is unfortunately quite likely

- the temperature sensor in the block may have failed. This will prevent the fans from running when the engine overheats, and you can see this. The fans are not driven by a belt. P68....

- the thermostat may have stuck closed. You will have to get it out and test it, but this is not difficult. See p328

- this model of Camry has a plastic top tank to the radiator, which eventually cracks. Look there carefully.

- it may be that a radiator hose has gone soft and closed up. Check they are allowing good coolant flow.

- it could be that in a car this age that the radiator has silted up and is not allowing coolant through. Disconnect the top and bottom radiator hoses, when cool, and run water through from a garden hose to get some idea about that.

2004 ford ranger v6 3.0 is overheating, what should i be looking for beside normal fluid check?

Check to make sure that your fan is kicking on when the engine heats up. If it is then the next cheapest fix would be to changing the thermostat. A typical thermostat is held onto the engine with 3 bolts under the top radiator hose. The part itself and seal if applicable may only cost you about $6 or a total of $20, once you buy another gallon of radiator fluid.

My mutsuibish shogun 1994 v6 keeps overheating and building up so much pressure that it keeps spliting the radiator hoses???????? PLEASE HELP

ur car is overheating because it does not have the capacity to dissipate high coolant temperature from ur engine to ur radiator or heat exchanger/ check auxilliary fan operation/ if electrically operated check fuse or motor condition/ if no motor check fans silicone oil/ could be too less/ check radiator condition it coul be blocked that why it restrict coolant flow/ check thermostatic valve condition could be stuck up and restrict coolant flow to the radiator...check coolant reservoir if water has oil in it/ if it has oil in it then ur engine cylinder head gasket is broken....

2000 ford ranger 3.0 v6 engine.coolant being forced into the reservior and both top and bottom hoses at radiator are collapsing.i have replaced the thermostat.whats could be problem

It's normal for some fluid to be forced into the reservoir during operation due to fluid expansion and pressure. Usually the fluid in the reservoir will increase or decrease depending on what temperature the engine is at. Unless your truck is overheating I woudn't worry too much; just make sure the fluid level doesn't get too low or too high in the reservoir. If it is running hotter than normal and excessive amounts of fluid are being forced in to the reservoir you might have a blown head gasket. As far as the hoses collapsing; I have a 2001 Ford ranger 4.0 V6 and I noticed that the top radiator hose appeared to be collapsing in one of its bends. I installed a radiator clamp on the hose at that spot just to keep it round and from pinching itself off. It probably happens from the heat; just keep an eye on it. It may be that your hoses need replacing; I know mine did the same thing after just having been installed brand new though. God bless you and I hope everything works out for the best!!! : )

Car overheating

First, plastic tube may be the overflow vent from the coolant bottle.Check to see where the attached end goes. You are going to have to check engine for coolant leaks (carefully refill system without spilling anything, then look for dripping anywhere. Look for leaks from all hoses, fittings radiator, water pump etc) After checking for leaks, start it up and check again (watch where you put your hands though) While running, check that the fan comes on when the vehicle reaches operating temp.(no fan, check fan motor, sensor & relay) Turn the heat on (does it have heat?) Check temp of lower hose and upper hose. If overheat happens, is lower hose still cold? (likely bad thermostat). If you found a leak, replace whatever is insurance is to change thermostat after any overheat. Last, is there any white smoke from tailpipe, does engine run rough? If so, could be a failed head gasket or crack in cylinder head. (at this point last thing to worry about unless there is excessive smoke or rough run or oil in radiator or coolant in oil).

1990 ford ranger is overheating

If the cooling system has no bleeder valves to vent air, you may have to temporarily loosen a heater hose to get all the air out of the system...Also check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem....Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.
