1988 Ford Taurus overheating. Already replaced cracked radiator, thermostat, water and pump. What else can it be?

Only 1 thermostat. You should be able to feel the pressure in the upper hose if the pump is working. Compression test to check for cracked head/blown headgaaket, are the cooling fans work I g...lots of possible causes.

have a compression test done as the bubbles suggest a blown head gasket or cracks. That will account for the overheating. The oil leak may be from the head gasket or cracks.

!st check and make sure the water is flowing in the radiator, then check
the timeing, Mazda will run hot if the timeing is rong.

Could be a leaking radiator and a broken water pump: not enough water-> hot -> steam -> high pressure : blows the weakest component.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/robert_573a00ba7e399076

if its a 3.0l 2-valve it could have a head gasket or cracked head.
if its a 4v dohc 3.0l it could be the water pump that driven by the
bank2 camshaft... the impeller inside the pump comes aprt and they overheat

Sounds like your water pump might be going out have you tried flushing the radiator to make sure its not blocked. You changed the thermo so it could be a clogged radiator a bad water pump

OHV engine. I have seen these wear the blades off the waterpump. Does the heat work.

it could be water pump, radiator fan, check system for leaks, or you might need a new radiator

thanks

To solve the problem you have the things to do in this order;

) When the engine is cold top off the radiator with fluid. (When the pump was replaced the fluid should have been also)
) Make sure the radiator fluid has anti-freeze in it. This is also anti boil also !
) Add fluid to the overflow reservoir.
) Make sure the drive belt was replaced on the water pump.
) With the engine running, you can add fluid to the radiator for the first minute or so. You want to get air pockets out.
) Replace radiator cap.
) Let car warm up. When it's hot you should get the radiator fan coming on.
) When it get hotter the air-conditioning fan may come on.
) If the fan does not come on, the heat sensor is probably bad.
) If all fans come on, and it overheats, you may have a bad thermostat. Trace the upper radiator hose to where it connects to the engine. That's where it located.

Do not operate the engine when it overheats, You will damage the head gaskets and cause radiator fluid to leak into the cylinders.
If you smell radiator fluid in the exhaust fumes, it may already be leaking.

radiator replace or get rodded check radiator temp at top and bottom should be about 10deg differance
