Car operating very hot after repair
Last week my engine overheated after the radiator leaked and all the
water poured out of the cooling system.
I had a new radiator installed and all the damaged parts repaired in
the engine (head gaskets, glow plugs, oil, thermostate, etc). Damage
was pretty bad. The mechanics didn't see cracks in the block.
The car works after the repairs, BUT, it's running very hot. At idle
the temp gauge sits at 90 C, driving on city streets or at highway
speed (65-75mph) the temp gauge is at 110 C. If I put the A/C on the
gauge goes just a smidge below 120 C (which is the overheat mark). So
the car doesn't technically over heat but it is running hot without
the A/C on. If I had the A/C on it would probably over heat.
After a 20 minute test drive with no A/C on, and the gauge at approx
115 C the whole time, I got home and opened the hood. Lots of heat and the water in the bottle was boiling and hissing out of the bottle cap.
Any ideas what's going on? Car used to run at 80-85 C before the repairs.
