My mechanic replaced my radiator hoses. 2 weeks later, one came loose and the engine overheated and died. It was put back on and 2 weeks after that, the hose began to leak. I brought it back and both hoses were replaced, said to be faulty. An external compression test was performed but not internal compression test. What does that mean and should I take the car to another mechanic for further testing or monitor the car for a while first? It seems to rev higher upon acceleration, to 3RPMs but I have not had the car back for more than a day.

    I'd try a different mechanic, hoses coming loose and/or bursting soon after being replaced could be a sign of poor workmanship. – GdD Feb 23 '17 at 10:55
  • Welcome to the site. More specific information about the car (make/model/engine) would be helpful. Also, which question are you seeking an answer; "what does that mean" or "should I take the car to another mechanic"? The later will likely result in lots of opinions. – CharlieRB Feb 23 '17 at 12:58
  • What makes you think there is anything wrong with the car? – Sir Swears-a-lot Feb 24 '17 at 8:54

  • It runs fine, went 500 mi over the weekend, just getting higher rpms than usual at acceleration and on inclines... up to 4 at times, not in red zone. – Tck Feb 28 '17 at 23:49

leak test is the system pressure and head gasket,

change the thermastate 20$. get some bug remover on the rad and gentle wash it with a hose from under the bonnet side.

check electric radiator fan switch or sensor needs replacing.

make sure all air is bled from the system when refilled and open the heater controls to hot as well. good luck.

  • fan is fused so check that. – user26112 Feb 24 '17 at 18:23
  • How does this diagnose engine damage? – Chenmunka Feb 24 '17 at 18:36

Do a compression and leak down test of your cooling system to see if the head gasket has failed. There could be more catastrophic damage also, like warped head!!!
