Engine Cooling problem
1990 Chevy S-10 6 cyl Four Wheel Drive Manual 160000 miles
My truck started to over heat a few days ago. I replaced the water pump on because it was leaking from the weap hole plus it sounded like it was about to go out before long. It is still over heating! It starts off running normal temp but after awile it hits 210 then it slowly makes its way up to 260 and sometimes it will drop a little a then go right back up. I put another thermostat in it still nothing. I thought maybe the coolant sending unit was bad so I replaced it an no luck. It got so hot on me today it blew steam and I thought it was on fire! I let it cool down then I took the thermestat out thinking that it would run colder and get me home but It still went to 260. Over the summer I put a new heater core in it and I have heat so I know its not bad. I'm not losing any coolant or anything. I would greatly appreciate it if anyone could help me. Thanks!
have the same problem?
