    Changing your coolant every 1-2 years makes your thermostat last longer makes your rad less prone to leaks and costly repairs makes hoses last extra long.

    I have a 2000 Toyota Camry 4 cylinder it's overheating. It started only when driving in city traffic not on the interstate. I tried to flush my coolant and change my thermostat. Radiator must have had water in it because it was corroded very badly. I'm still getting hot air through my heater core most of the time when my foot is on the gas. When I slow down it starts getting cool do you think it's my radiator or should I flush my heater core also. Which is the inlet and outlet on the heater core!?

    One big tip to make sure your cooling system works properly. If you ever have to remove a serpentine belt to work on your vehicle, make sure it goes back on the.correct way. A friend of mine couldn't figure out why the heater wouldn't blow hot air yet the engine heated up fast. Loomed at the belt diagram for the vehicle and the belt was on wrong and spinning the waterfall the wrong direction.

  • David Clough
    David Clough 16 days ago

    My first car the thermostat stuck closed. Could tell cause the transmission fluid started leaking out faster. And it was a weird looking thermostat. Had the GM part number on it, so figured it might have been the one that originally came with the car. My second car the fan motor wasn't working and the car was only 3 hears old. One auto parts store wanted 28 dollars for one, but had to order it and I wanted to change it that day. Went to a place that sold acdelco parts and they wanted almost 100 dollars for one. I told them I could order one for 28 from the other place. They said but ours is the official GM part. I said that's what's on there now and it doesn't work. So I went to a different auto parts store and they had one in stock for 31 dollars. So I put that on and it worked for all the years I had the vehicle.

    Screw these stupid combustion engines for over 130 years is the exact same crap and the electric engine was invented 1890 in Europe.

    • Samuel Giacinto
      Samuel Giacinto 19 days ago +1

      Pete Blazer Could be a bubble of air, if the bubble gathers around the thermostat coil, it will prevent it from opening. Try a flush/burp with the front wheels elevated to get as many bubbles out as you can! Happened with my Subaru once, overheated/struggled to cool itself off with the T-stat and worked fine without it until I flushed/burped it ☺️

    Rubber softener is a must if you have a convertable with a hard top. I drive a Focus CC and lubricate the roof rubber two or three times a year. The result is the roof is very much less likely to leak.

    i always buy the failsafe type thermostats that stick open if the wax motor leaks etc. not OEM, but a bit better piece of mind knowing that the result of a failed thermostat is an engine running a bit too cool.
