Question about Cars & Trucks
Vehicle is overheating. When replacing the thermostat I realized that coolant is leaking at the base of the unit that is holding the thermostat. Is this a major repair or something I can do myself? It appears to just need to be resealed similar to what I did when replacing the thermostat.
If you can see a separation all around the area that seems to indicate a separate part, then you can change the seal on it...if not, the block is cracked and will need to be epoxy sealed.

Hi, Sounds like you have tried about everything. Ok the aux. coolant switch is for the electric pump for the heater core will not cause an over heating condition just a longer warm up of the heater core. Has the cooling system been bleed properly if there is a trapped air pocket it will not let coolant circulate. Was the new thermostat installed correctly? They have a vent that needs to be towards the top or they trap air on the back side and cant take an accurate reading to open and close. Other areas to look at would be proper operation of the fan clutch, if they fail they can cause the fan to not lock up properly and supply enough air movement through the radiator. The aux. electric fans and their temp switches do you hear them coming on are they coming on at the right temp.

Hello, if you are losing coolant as you say than the most probable place is through your head and into your exhaust system, it is highly likely you have a cracked head or a major head gasket leak. The only other place it can go is if you have a automatic vehicle with the cooler on the bottom of the radiator tank (crack between two tanks), it will go straight into your transmission, you can tell if the transmission oil is overfull and watery (thin and whitish).

Hello and welcome to FixYa!
If you have overheating problem, it can lead to multiple
issues. You may be running on low coolant that's why the vehicle overheats. If
that's the case, please add coolant and make sure that it sits on the right
level, too much coolant can cause overheating too for coolant will overflow.
The vehicle may have a faulty or worn out radiator blower
motor that's why it overheats. If that's the case then you will need a blower
motor replacement to resolve the issue.
If the radiator is clogged with dirt and rusts this issue
occurs too. The coolant doesn't flow normally on the cooling system if it's
clogged. If that's the case, I strongly suggest that you have the radiator
flushed to drain out dirt and rusts. If you think that the radiator served you
enough then it's better to have it replaced.
Please do check the radiator hoses, If you have worn out
hoses it can cause coolant leakage which can result to overheating. A tiny hole
is good enough for the vehicle to overheat.
A faulty thermostat sensor can cause the issue too. If you
have worn out thermostat, the fan may not trigger that's why the fan won't work
when under stressed conditions. A blown radiator blower fuse can cause this
issue too so I suggest that you check the radiator blower fuse and replace it
Hope you find this information helpful enough and thank you for using FixYa! Have a good one!
