Mahindra Scorpio cooling system thermostat

SOURCE: 1999 cadillac deville overheating

my husband did everything that everyone else did that had this overheating problem. It was so weird that my engine cooled at a light and heated up going down the road. I have a north star 4.6 engine and this is natorious for happening. my check engine light also came on and so I had a diagnostics done which told me my #1 injector wasn't firing , car ran like **** as well. After putting in a new water pump and plugs,ect. and realized injector was good a friend told him we could have a blown head gasket. So just to see if this was the problem I went to buy a bottle of glassbeads and the auto parts guy told us to purchase a bottle of BARS STOP LEAK BLOCK SEALER NOT RADIATOR BUT BLOCK SEALER $31.99 . He followed the directions and we waited 24 hrs. before driving it. What ever the problem was has stopped my car runs like brand new and I am loving it again. no over heating no injector problem, runs great.......I hope this helps. I know its probly a temperary fix but its a fix and now we know what the problem was. SASSY

SOURCE: cooling fan runs continuously, trying to locate the relay switch

Should be located in front of left frame rail (pictured below). May have to remove the left headlamp capusel and air intake cover to gain access to relay. You may also try from underneath vehicle before removing these components.

SOURCE: cooling fan problem on 1992 pontica firebird

The cooling fan switch is built into the ECM. The ECM tells the fan to turn on at about 220 degrees. If you have a bad coolant temp sensor you might have trouble there. Usualy I find the relay or fan motor to be the problem. In some cases the ECM or CTS is the problem. I hope this helps.
Thank You,

Hello there"
sounds like you have done a lot with this there is a few things that you can do to ensue every thing is running right.
first if you can get a handheld thermal gun and check the temperature at the temp sensor on the radiator or block then see what it reads compared to the guage to ensure the guage is correct.
next check the temperature at both the top and the bottom of the radiatoer if there is a big difference in temps the radiator is partially blocked a radiator will increase 30 to 100 degrees if the radiator is 20 percent blocked.. also check to ensure that the radiator hoses are not collapsing.
Now ensure that you are not gettin air in the system by way of the water pump gasket or by loose hoses ok?
and finaly check to ensure that the heater core is not leaking and drawing air into the system or is clogged this will make a vehical give the overheating symptom also ok?
Let me know how this is going
Best regards mikle

Generally if one hose is hot, and the other hose is cold it indicates that they water is not circulating. You could have a defective thermostat. Take the thermostat out and run the engine without it. With the radiator cap off you should see a lot of water moving through. It that is the case, replace the thermostat and you should be ok. If there is no rapid movement of water it may be the impeller on the water pump came loose. This is rare, but it can happen since the impeller is usually pressed on the shaft. You should also check and see if you get a lot of bubbles when the car is running and the cap off. This often indicates a blown head gasket. Hope this helps.
