Question about 1993 Ford Ranger SuperCab

Datsun200B overheat/losing water, mystery?

My Mechanic is going crazy trying to figure out where this water is going. Not enough indicators point to a head gasket problem for him to pull it apart yet. Intermittently it's getting hot, mainly on short trips, and once cool, I find it's lost between 1 and 2 litres of water. If I put the heater on when I see the guage rising it cools it down immediately.
We've replaced all hoses, cap and thermostat. Tested for a radiator blockage. Can't see any problem with the water pump or fan. Fixed a small leak into the exhaust manifold...does anyone have any ideas?

    Already replaced the cap, it's been pressure tested for 3 days now, not losing pressure. This only happens every now and then. I'm just not wanting to do any damage by continuing to drive it? Also replaced all hoses and thermostat.

Try something as simple as the radiator cap it might not be holding pressure and evaporating out while you drive

    well i can tell you if you check the oil and there is no coolant on the oil it probably isnt the head gasket..other than that look around by the exhaust manifold for coolant leaks..if its leaking out of there and burning off on the exhaust you would never see the leak..

2.5l. Where is the bleeder valve for the cooling system?


Check on top of thermostat housing, there could be a bleed screw on that. If not there locate two heater pipes that travel in the engine bay toward the dashboard. These lead to heater matrix inside the car. If you follow these with your hand the higher one may have like a plastic screw moulded into it. If its there loosen it ( but not right out. Cos you will drop it) also be extremely careful as this is very hot water! Leave it open until only water (coolant) comes out then tighten it up good and tight. Once might not be enough. It could also be somewhere on radiator body but high up. Low level bleed screws don't work as air always rises

Overheats on hot days changed cam sensor thermo still stops till it cools


These are tough to figure out sometimes. To name just a few, radiator hoses colapseing, see if there too soft when you squeeze them, head gasket, is the oil white looking that would indicate a head gasket are you losing any water in the radiator.. see if air could be getting around the radiator maybe a rubber seal is missing. Like i said tough to figure out, just keep looking..good luck

Overheating and no heat


With what you describe sounds like the hot water is just heating up but not circulating and cooling correctly. Possible causes, airlock, faulty water pump, check fan belt tension, not broken etc, blockage in engine water way or collapsed hose. Are you losing water at all? Head gasket?

I am not getting as much heat as I should be. The dealer indicates a small leak into # 2 cylinder thru the intake manifold, but the heat should still be there, also they say the thermopstat is OK. ...


The heater core is the highest point in the cooling loop, so as you lose anti freeze the heater core is the first thing that dosen't get any hot water, and if you lose enough fluid the thermo couple will not be under water so that even though your engine is hot the gauge won't read correctly. get that leak into the cyl. fixed, it's going to give you trouble until you do.

I just purchased a 1999 Cadillac Deville. Drove fine for a few days. Today I drove 75 MPH for 20 miles on freeway and car began to overheat. Dashboard told me to replace oil. Checked the coolant, it took 1...


When a Cadillac (Northstar) overheats, It will give the message to change the oil. If you run a Northstar and keep running it long enough it will start shutting off cylinders and stop the A/C compressor to help protect itself. In this condition I would check for a blown headgasket. Possibly your technican will find the problem. Could also be stuck thermostat, dirty radiator Thanks

What is the coolent reserve tank for???? IF broke does it need to be fixed immedatley? Mine is busted and I was wondering if my car is going to overheat now. THANKS


The coolant reserve tank is a medium for the radiator to breathe. Water passes from the radiator to the coolant reserve tank and fort.

The car might not necessarily over-heat if the coolant reserve tank is broken, but it is advisable that you replace it to enable it serve its purpose within the operations of the car engine.

Good luck.
