My temperature is somewhat unstable....it sometimes go up half and a bit more then after a while goes down again....ive already changed my aux fan,made it bigger,my temp sensor,thermostat gone already,nothings wrong with radiator either....ive also noticed that this happens when the weather is hot.is this normal or should i look into more serious problems???does it have any connection with my compressor?please help me figure out this puzzle

Replying to: mitchicoi (Jun 07, 2009 7:43 pm) I had something similar happen on a vehicle about 6 months ago. Nothing was wrong with thermostats, radiator, etc. So it HAD to be a problem with the gauge itself or the connections leading to the gauge. Turned out there was a cracked electrical connector on the back of the gauge that would make or break the connection depending how the car was moving. When the car was cold, it would seem to operate just fine with the needle slowly moving up as the car warmed up. Once the engine reached operating temp, the bouncing needle would start to show up. The needle would never indicate a higher than normal operating temp, so I was pretty sure it wasn't a cooling system problem. My guess is that the wires leading to the gauge would become a bit more flexible once the engine compartment heated up and the movement of the car (especially when accelerating or decelerating) would basically wiggle the wires and make or break the connection, causing the needle to suddenly drop and then just as suddenly come back up to show a correct reading. |

Both door locks on my trusty hatchback are failing. The driver's side one works but not well, and the passenger side lock is frozen. Apparently what happens is that the little internal sliding "cover" inside the lock comes loose & falls down into the mechanism, jamming the lock. I wonder if it's possible to disassemble the lock mechanism and remove the cover piece. Has anyone done this? I don't think I want junkyard locks - even if they happened to have the keys, I don't think used locks would last very long. I'm willing to buy new ones but can't find a "keyed alike" pair anywhere (I don't want a different key for each door).

Could sure use some help from someone more knowledgeable than I: Car in question is a 1989 Mercury Tracer, but these have a Mazda 323 engine. It overheated, and I'm pretty sure the head gasket blew. (Milkshake oil, water drip from exhaust, etc.) I decided to try liquid glass on the head gasket - specifically, "Bar's Leaks Head Gasket Repair" - but I'm still having problems. I should mention the steps I've taken so far (some of which were just for maintenance): - Replaced the thermostat. - Back-flushed the cooling system. - Flushed the heater core separately. - Replaced the radiator cap. - (And as I said, added liquid glass.) What's different now: The good: - It starts and runs better. - There's no more sign of coolant in the oil, nor oil in the coolant. The bad: - Smoke is still sputtering out of the front of the engine in some spots, which I take to be unsealed cracks at the head gasket. - The heater isn't producing hot air. - The coolant overflow reservoir still bubbles (presumably from exhaust gas.) I'm wondering now if the water pump is bad, and that maybe the liquid glass can't fully circulate to where it can seal the cracks. The radiator hoses stiffen up when the engine is running, which I would have thought meant that there's pressure and that the coolant is being pumped through the system. Except that the top radiator hose gets warm/hot while the bottom hose never really does… I'd rather not replace anything else without knowing that I've nailed down the cause though. Any suggestions? Thanks much in advance.
