Radiator Temp. How can this happen???
OK. Here is my deliema. We have an 87 Allegro 33' MH with a 454 an 58K in miles. We just had the radiator flushed and pressure tested all was good. Will be calling the mechanic tomorrow about this also. This was our first extended trip (over 50 miles) 180 miles each way. With normal elevation changes (nothing big). I think the temp gauge on the dash is faulty, but what would cause the gauge to go to redline at 60 mph, with a normal load and drop to less than 1/2 at 30 mph. At one point we were in stop and go traffic on the freeway (accident) and the temp was great. After getting up to freeway speed it went to redline again. We will be replacing the gauge next week before next trip.
Thanks for your imput
Only problem with the coach on first longer trip. Had a great camping trip to Battleground Lake State Park. Highly recommend.
