spud94 Posted July 31, 2014 Share Posted July 31, 2014 My car seems to get really hot when in boost I have a civic half rad and check for leaks and found none, fans constantly on and got good completion across all 4. Flushed the rad out and still gets hot it's had a new water pump and belts last week just don't no we're to go from here I can only think that the rad cap is letting water pass through to the overflow causing my car to over heat.

morgey Posted July 31, 2014 Share Posted July 31, 2014 Do the heaters in the car blow hot? Link to post Share on other sites
ttestarlet Posted July 31, 2014 Share Posted July 31, 2014 Sounds like your thermostat is stuck closed. If your not getting hot air inside the car then it's most probably that or a blockage. Holts do a 2 step rad flush which is really good. Link to post Share on other sites
