Hi! Was the thermostat and other items replaced due to this overheating? you say coolant level full? maybe your header tank is full but the system isn't? Try bleeding the system. From cold, start the engine with radiator/header tank cap OFF stay with the vehicle and have some very warm water handy. DON'T look over the filler but watch it as the car gets to operating temperature if the water drops drastically top it up with warm water again stay with the car it may take a long time to level out. If the car is bubbling furiously and doesn't want to settle then possible HEAD GASKET Failure or Water pump.
Does your oil look milky on the dipstick? is there an excessive amount of water coming out of the exhaust? are your hoses swelling with radiator/header tank cap on at operating temp?
Sorry to be the possible bearer of bad tiding if the Gasket has gone, but better to sort it now than cause irreprable damage?
Hello again Melissa, great news that the oil isn't contaminated. I still think an air lock could be the cause as the heater Matrix will have been completely emptied when you has the tap? replaced.
As for the fans not kicking in it would take a darn good while before she boils over if vehicle is stationary on tickover.
Please let me know any more if you can after bleeding the system,
Cheer's

I am having holden barina 1996 3dr manual. one of the fuse (30) fell down and my audio is not working. i was trying to locate where it fell from but could not. can anyone help me to find that. thanks in advance
Hi there i have a 1996
I also have an XK8 that had overheating problems. After replacing the therostat and the problem remained, I removed the water pump and inspected it. It turns out Jaguar used plastic impellers in their water pumps that often fail. I replaced it with an aftermarket pump with a metal impeller and problem solved. wjhxk8

Hi
Thanx for your helpful advice onyeredson, I too suspected an air block in the radiator but discounted it when the filler tank was full. In answer to djishere's question the thermostat was replaced over 8 months ago and I thought unrelated. The car has had previous electrical issues and I was told that it may be the fan not switching on??? I'm just guessing here and onyeredson's solution seems to make sense. I'm a bit curious as to why the problem arose the very next day after work was done on the heater tap????

Hi onyeredson
There's no oil in coolant or water in oil from dipstick. No white murkiness.
I've got honda civic lxi '97, it got overheat last wednesday.They replaced the fan but last fri, it was hot again. Last saturday, they cleaned the aircon and did other mechanical stuff. But when I took it home from the shop, the car is shaking everytime I change gears. Yesterday, it was cold for few minutes but the aircon doesnt blow cold air this morning and as if the car has difficulty running. Even if I step on the accelerator, it is still slow.
sure the thermostat put in right? pluged rad?
