Need help.
93 SP overheats (O/H) after running well for 20-30 min - alarm, no water from rear. Dealer checked and blew air through system, tested 40 min and fine, but O/H again after 20 more min. Same over and over. Any ideas? Is there a pump that could stop working after 20-30 min and then be ok after being blown out? Has very few hours but did sit for a few years (after winterizing) before being used this year.
