Overheating?

[mannyS14]

I own an '95 240 that I bought a couple of weeks ago. For some reason my temp gauge shows me my car is overheating. But it only shows me this for a few minutes and then the needle drops down to normal . I bought it from a dealer and whenever I was testing it out, the guy told me that they had suppousevely checked the temp of the car many times and it was fine. He said that the gauge might not work. But I don't trust guys in suits smiling at me the whole time . When I was doing a tune up last weekend, I noticed that my upper radiator hose looked like it had been "sucked" from the insides. So I replaced it. But this weekend I checked it, and it was the same thing again. I don't know what to make of this. I need help! thaks!

Sounds like a air pocket in cooling system..bleed the system..One stupid quick way leave radiator cap off, heater on full, start car, top off radiator with water/antifreeze..let it settle and blurp over. (Ideal to jack up front of car a bit, if you can't you can shake the front end up/down to help air to rise to top.)Things to check after..-Leaky waterpump from weap hole/hoses for small leaks. -Coolant temp sensor if gauge still doesn't work properly
