1998 Grand Marquis LS Overheat


No indications ever of overheating, then yesterday I was only driving for about 20 minutes and the "High Temperature" indicator went on. This was followed by the "Check Engine" light a few minutes after. I drove it back to my house for the approximately 4 minute drive and it was struggling to make 35 km/hr.

I opened the hood and checked that there was engine coolant in the reservoir, but did not check the level inside because the engine was very hot.

Please help...what is going on?

Can be many things. Cheapest would be the thermostat. Then the waterpump, most expensively would be the timing belt. 200,400,1100.

My 1996 grand marquis keep overheating

there are several problem that will give this indication and your information is not comprehensive enough to make a good diagnosis
the time factor is critical as some time could be 5 minutes to 5 hours and driving is too loose as it could be at highway speeds or stop go traffic , hill work or under load
so I will give to certain conditions that will over heat the car or cause a rise in operating temperature
head gasket--check with compression test
low water level-- check at cap
faulty radiator cap--have tested
partially blocked radiator--have a flow test done
fins on cores falling off --replace radiator
overheating transmission oil--check the transmission is fully operational as high speed with out over drive in will cause a rise in temp
if in traffic --check viscous fan and fan operation if electric
if under load -check load and tyre pressures
check for brake operation- adjust hand brake to full off
run the fault codes to check air/fuel ratios and timing
check for failed cat converter-- blocked exhaust system

The engine light keeps going off and on and the fan stays on for 20 minutes after the engine is off

Have a shop test this for overheating, I think you have a big problem here. The light is indicating the overheat. Do not drive this or you can ruin the engine.

My 98 grand marquis keeps overheating i have changed mt intake manifold,thermostat and radiator my car will overheat to the fullest and then all my antifreeze will leak out

Hello, By doing RR most of this doesn't work. What you really is a auto technician to run some test on you car. The one test they really need to do is a pressure test on the coolant system on this Mercury GM. This pressure test will indicate if there is a leak down. That is, coolant is leaking. With coolant leaking a a closed pressurized system isn't best thing for these modern vehicles.

The coolant system is a closed system and the manufactures designed the system to hold pressure above 240 degrees. By raising the boiling point by pressurize coolant system.
This helps pollution system to operate more efficiently. GB...stewbison

I have a 98 grand marquis it keeps overheating I changed my radiator,thermostat and intake manifold the car will drive well then start to overheat and once it overheats all the antifreeze will leak out

This could be a broken head gasket, cracked head or block.

Pull the thermostat back out and you should be able to see water flow through the radiator. Make sure the water pump is working.

Were does the antifreeze leak from?

2004 Lincoln LS V8 overheating!!

check your radiator fan if its powering on when engine runs hot. Test if there is power at the fan's electrical connector when car is running and temp guage is at half. If there isnt any power on, check your relays and fuses. Hopefully this helps
