Termostat, radyatör kapağı, disku fanı ve EGR soğutucusunu değiştirdim, ancak yine de sadece yokuşlarda aşırı ısınma sorunu yaşıyorum. Nedir bu sorun? Yardım edin.
Blown head gasket check then Blue devil in radiator fixed it when workshop quoted $6k to repair still going after few 1000k. Thermstat too low down so bubbles collect around it faking a cooling effect so thermostat stays shut. At moment still to reinstall new thermo by next winter down under.
Thanks mate for the info. Did yours lose water and only over heat on a hill??
It overheated to steam overflow after 5mins of driving but we left the car in the paddock for a few yrs while we researched the bluedevil treatment. Tested it on a 81 honda civic and that worked. Then our Ford Ranger was filled with contaminated fuel, so necesity became the motivating factor as we had no wheels. My hunch is leaving it all flushed with no coolant in the water may have corroded the crack in gasket that allowed compression gasses into cooling system. This caused a pressure cooker effect and the thermostat being at the low point in the system it misses the extreme heat buildup at top of radiator, staying closed and allowing a vicious circle of pressure cooker high temperature water gushing out into overflow bottle. Maybe similar as the thermostat placement and no design to handle cavitation gases keeping the thermostat cooler than the cooling water actually is due to the insulating effect of the cavitation gases. Some i read tried drilling a 8mm hole in the thermostat plate to get rid of cavitation gases if they form. I will keep the thermostat out over our hot summer to give the blue devil good opportuninty to penetrate any compression leaks into radiator water. Good to check compression with any low readings indicating the suspect cylinder. If it is one, leave the spark plug lead off, and plug loosened so compression gases do not blow back the blue devil sealant in that cylinder. You idle the car for about 1 hour. So you do not want it to overheat during treatment.
I have the same problem in my 2010 ranger any more information would be appreciated
Look up and view youtube vids on BlueDevil head gasket sealer and closely consider both good reports and bad reports and consider who gains most from the repair adice options. May be I was lucky and leaving the car "in the paddock" for a few years like RR did with its blocks b4 they installed in cars corroded the compression leak or crack closed.
