My temp gauge goes up when i drive for a good 20 mins, and most of the time during summer in the hot air it goes up very fast
and it overheat although i'd just drive it for 10 mins or so, but the gauge temp drop back down when my car accelerate. The coolant in the coolant box boils when i check it. Does this sound like a thermostat problem, or radiator? I don't see any leak from the radiator at all. My coolant box have been very dirty inside so i'm not sure what is clog up.
What makes this problem better or worse?
It's worse when it's summer time
How long has your 1998 Honda Accord had this problem?
RepairPal Certified shops can diagnose and repair your 1998 Honda Accord. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Could be a number of different issues. I thinking possible cooling fan issue, or maybe something as simple as a radiator cap no holding any pressure. 10 min of driving with engine hot is no good. Could possible have head gasket issue as well. Recommend letting a professional mechanic check it out for you.
