Overheating? s type

My temp guage never goes above the 1/2 way mark, yet my cooloing fans come on all the time even after driving it only 15 minutes. Yesterday( after a year at least with no problems) my guage pegged out and the overheat light came on. My heater also does not blow hot air, and its been like that for about a year.are these related? and can it be a bad thermostat? I find it odd that after my car says its overheated, the needle shows an ok temp in as little as 5 minutes after I turn off the engine. If it were really thaT HOT IT WOULDNT COOL DOWN THAT QUICK WOULD IT? could my thermostat be intermitantly stuck? would that cause both problems?
can some one tell me how to change my thermostat, if this could be the problem?

Had the exact problem. Turned out that it was the thermostat that needed replacing, relatively cheap and quick by mobile mechanic. Things were fine for a year and the second time it happened I assumed it was the same problem. However, this time the thermostat was fine, wasn't sticking, and I had a slow leak in radiator, losing colant and causing engine to overheat, which paradoxically had stopped the heater working as well. Had to get new hose also by local mobile mechanic and everything seems okay again except for the intermittent "stuck in park" problem that a lot of people are also experiencing.

I have a 2002 jaguar X type. For some reason, the temperature gauge in the dash now periodically shows hot to the max.. all the way over. But the car is not overheated. What can that be? It's really scary. I work at night. Get off at 3am. DO NOT want to be stuck by the side of the road. Anyone familiar with this? Had a new radiator put in back in April. Don't know if that's related. This problem started about 3 days ago. But last night, on my way from work, it kept showing completely overheated, but it wasn't. Sure would like to fix this... myself if possible. Appreciate any help. Thanks

1994 vw golf 1.9 overheating

First question is what constitutes "overheating".
Since the car has been parked for years, the thermostat could be sticking closed.
The cooling system could have air pockets and need to be bled.
The water pump may be corroded inside and not pumping enough volume.
If the gauge goes above half way, the fans should start up. But half way should be more or less normal, not hot yet.
I would look at flow problems first, beginning with removing the thermostat and driving it without one for a few days. Also check and see if there is a process to bleed the cooling system of air.

Cooling fan stopped working, changed the ect, now temp guage shows overheating in very few minutes. What next?

First question is: does the fan come on at all, even as the temp begins to rise on the guage?
If not, check the relay or the sender for the temp (that may be what you replaced) Then look at the connections for the fan--- and, have you checked the fan for operation with known 12v source?

Speedometer doesn't work and car occasionally overheats

u need a vehicle speed sensor(vss) it is located on top of the trans about 60-70 dollars for the part and 10 minutes to install go online and find the vehicle speed sensor location for ur car there is only 1 bolt to remove it u will need a 10 mm wrench and there is one connector but always check the basics first check all of ur fuses with test light or with car off pull each fuse and check to see if there blown if u see a burn or break inside the fuse it is bad replace it. but i'm sure it's the vss. as for overheating check coolant level start car let it get warm/operating temp with the hood up watch to see if the cooloing fan comes on (make sure ac is off because when the ac is turned on there is a seperate fan that will run constently untill ac is turned off.) the cooling fan will come on for 15-30 secs and go off if operating normally if the fan does not come on which happens to all cars like i said check fuses and switch cooloing fan relays to see if it comes on try spining the fan by hand with car off and no key in the ignition u may feel the fan is locked up or damaged

2002 chrysler 3.5 overheating - new rad, water

It can a the first stage of blowing head gasket.

Fill your coolant tank to the full mark when it's COLD.

Start the car, and pay close attention to the tail pipe for a small puff of white smoke.

After 15 minutes,If you do see any vapor then take the car for a 8 minutes drive.

Park the car and listen for bubbling sound from the coolant tank,

If you see bubbles coming up then you will need a head gasket change real soon.

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.

When you mention the radiator having a hot upper in pipe and a cool bottom out pipe tells me that the coolant is not moving around the engine. This could be down to a water pump not working, blocked radiator, thermostat not opening. The bottom hose should be cooler than the top hose but once the engine is up to working temp which is around 85/90 degrees c for an audi the bottom still should be farly hot to touch. Hope this helps

Engine Overheat

if the guage goes down when you drive then it is most likely the temp sensor that detects heat and kicks on the fan.

Overheating engine: termo guage at the middle during idle

The Temp gauge should read in the middle of the gauge at operating temperature. This is normal. The radiator fan should come on after idling (not driving) for 20 minutes. The fan should also come on when you turn on the AC. Are you experiencing overheat problems?
Please reply if you have overheating issues.
