The vehicle is a 1998 Mazda B4000 with 151500 miles. The problem is the water temp gauge stays under the low line for a few minutes after starting, then spikes to the high temp line and then settles to normal temps. It will occassionally spike high while driving and then come down again. I control it by driving with the heater on and turned all the way up. What is the likely problem and how can I repair it myself?

The likely problem is an air bubble in your cooling system. Recommend you park on an incline, remove the radiator cap, start the car and let it warm up until there is flow in the radiator. Fill the radiator and keep it full while the engine continu ... 1998 Mazda B-Series

The fan for the heater/vent/AC is stuck on high and remains running when the vehicle is shut off. I am able to switch from vent to heater to AC to defrost, but the fan always stays on high. This is a 95 Buick LeSabre.

Does this have auto temp control where you set the temp number or does it have a knob you set 1-5. I'll bet you have auto temp. and you need to replace the blower control module under the hood. ... 1995 Buick LeSabre

I just changed the rad and thermostate on my 2006 cobalt ls. I've refilled the coolant via the overflow reservoir and it too in about 5-6 litres. I start my car with the heater on high, cap off of the reservoir until about 90 degrees celcius to ensure the thermostate opens. Put the cap back on the reservoir. I get lots of heat in the car but the rad hoses stay soft and the upper hose stays cold, the bottom hose gets warm. I think I have an airlock. I tried raising the driver side of the car up o

Did you check the water pump? The hose should be firm when you cold start the vehicle since the thermostat is not open. Once the thermostat opens the coolant will flow provided the thermostat is working and installed in the correct orientati ... 2006 Chevrolet Cobalt

My high beam in my 1994 Landcruiser is not working when I push the lever on. Sometimes I think I can smell a slight odor of melting plastic when the heater is on. The high beam lights work as long as I pull the lever towards me and hold it on. Also, in the same vehicle, the engine light is staying on even tho the sensors have been changed.

The high beam problem is clearly caused by a faulty lever switch - you will have to replace it.\012\012\012The engine light is on because the ECM has detected a fault - to find out what fault the error codes must be read with a special tool - a ... Toyota Land Cruiser

Antifreeze won't stay in reservoir. Driving along fine and all of a sudden indicator was where is should have been but only getting cold air. Drove for another 10 minutes and it shot from normal to high-overheated. Then the heater kicked in and the amount of heat it threw out was above the normal amount. Checked the antifreeze reservoir and all fluid had leaked out. Replaced the antifreeze and it leaks out with exception of about an inch in the very bottom of the reservoir. You can see it
