Question about 1993 Lincoln Mark VIII

Temp guage runs in the red! 93 mark VIII 135K miles

I have replaced all in the cooling system. rad, thermo, pump, send unit. The water temp is good/normal. However the guage says its hot... When the needle gets in the danger zone the computer sends messages to check system & will open up the heater as a safety back up canceling the air conditioner. Not good on a hot day.... The only thing left is a bad guage. I have doubts. when its cold/winter the temp guage runs a little above normal although not in the extreme. Now that the outside temp is in the 70 the guage reads in the red after about 20 minutes of steady driving.

    Antifreeze overflow or air vacuum will cause other problems....may b too late for valves, lifters and cam shaft. Ususally goes first from excess heat.

1995 Lincoln Mark VIII OVERHEATING after 2 thermostat s in a week.?

You need to find an honest Joe!! My first thought is get the rad checked. Any good mech would know how. It should be hot at the top half and cooler below, but even spread across the whole rad. You don't say if its forcing water from the header tank? If it is then its possible a head gasket has gone. If its been maintained but the coolant hasn't been flushed and replaced every 2 years then its likely the main rad is partially blocked. There is no ready cure for this despite a lot of additives and theories, the only sure way is to replace the rad. Is there no good DIY neighbour who could help? I understand your fears about some dealers but if in doubt take your DIY neighbour with you so they will behave.

I have a 2000 Saturn sl 1.9L sohc. My cooling fan is not coming on. I replaced the temperature sending, which did read a temperature on my instrument cluster, before and after replacement. If I have the...

first, is/was the temp guage showing over heating? If so you should have checked/ replaced the fan temperature switch on the radiator ( or follow the fan wiring to it's location) depending on air temp, and driving conditions, the motor may not need the fan. If it's not, cover the rad with something{paper,plastic} until the guage begins to show overheat condition, then the fan should start. # DO NOT LET IT GET INTO THE RED ZONE! If you keep the reservoir closed, the radiator will **** up the coolant after warming/running, and a cool down.

2005 Jeep Liberty 3.7L overheating

it's overheating, for sure,
is coolant levels dropping? cold checked at rad cap?
"pulled over and found a hose to cool the radiator and hose near the thermostat,"
i can not understand this statement"above"
if it overheat only parked, check fan for full ops.
if overheats moving too, wont stay cool moving fast
bad rad cap
bad thermostat , they have 7 year life says STANT. (and why)
belts slipping (to water pump)
rad cores blocked (IR thermo gun it) ask
water pump impellers rust 1/2 gone?

all this assumes no coolant loss, if you have loss, tell where.,
where it leans
passengers toes (foot well)
engine oil pan? milky oil
if A/T TRANS, check it for milky too.

My 93 jeep wrangler 4 cylinder temp gauge doesnt work right. when driving the gauge reads 0 when i step on the gas the gauge moves to the right temp. i have installed a new therm. new water pump new...

depending on how fast, this happens, could be an air lock in cooling syste, or a bad head gasket, or head. does the gauge ever go too high? can you hear gurgling in the rad, and does it ever push out coolant?

Overheating, guage not over 1/2 mark, overflow smells like exhast

Have you tried running car from cold, with rad cap off, & heater turned on, coolant topped up, an inch or 2 from top of rad? Let it run up to operating temperature, cooling fans kick in & out 2 or 3 times, and top up coolant as needed, then put rad cap back on, & fill return bottle up to mark. There may be a worse problem, but bleeding system as I have described, ensures all air out of heater core & cooling system, which has been cause many times before on all makes & models of vehicles. Especially when no heat situation. Let me know if it helps.

Temp guage keeps pegging out to high side.....

LOL, dont add to the environmental mess just yet!

have you replaced the sending unit for the gauge? its located usually in the intake manifold somewhere, or on one of the cylinder heads.

If thats not the problem, you may have a wire grounding out behind the dash.

my best advice is to try an aftermarket monitoring gauge with fresh wiring to the sending unit or sensor to check for this problem... hope this helps!

High temp

it sounds like an air pocket... try squeezing the rad hoses a few times and keeping an eye on the level in the rad... this is probably best done with the rad cap off... of course make sure it is cold before you remove the radiator cap.
