Why Radiator cap almost popped out?
89 Civic LX automatic with 224466 miles. I had first overheating problem after driving about 30 mins in freeway. The temp indicator almost reached to red. I immediately stop the car and open the hood and saw most of coolant was poured out. The radiator cap was half opened. I simply don't get it how comes the cap is half opened where the coolant got poured out. The hot coolant did not flowed to coolant reservoir but it flowed out through half-open radiator cap. I lost most coolant volumn. I waited 2 hr and bought new coolant and filled up the radiator and able to drive back to home. What caused the radiator cap half opened? Did my radiator cap was "loose" before I drove to freeway? is this normal thing? |

Was the car serviced by you or another recently? Cap is damaged/worn out. Radiator neck is damaged/worn out. Either of the last too is rare (I don't think I've ever heard of this type of problem), but possible. My suggestion would be to inspect the cap and neck for any obvious problems. If none are found, replace the coolant with Honda coolant (if necessary) and reinstall the cap. Carry some water with you and monitor the situation carefully. If it doesn't happen again, the cap must not have been on correctly. |

I have had to occasionally check the coolant level since the waterpump is little leaking... I do make sure fill enough of coolant level...however I remember I did not check the level three or four weeks which caused to lose significant amount of coolant that must have caused the overheating. I assume that I did not properly tightened the cap and drove the car with loose radiator cap with not enough coolant. Big stupid mistake....I checked the cap and radiator neck as you suggested and I found nothing wrong with it. If the overheating happen again, it must be faulty thermostate... |

Big stupid >mistake... If the water pump is leaking it will soon blow all of its bearings out. When that happens, it will seize up or allow the timing belt to come off. When that happens the pistons will probably hit the valves and the engine will be wrecked. Assuming that you want to put the money into this car, you need to replace the timing belt, water pump, idler pulley and refill the system with Honda coolant. This will cost a few hundred dollars. If the rest of the car is in good shape and you don't have any other transportation options, you have to bite the bullet and do it. >.I checked the cap and radiator neck as you suggested and I >found nothing wrong with it.

Honda designed the system to draw coolant out of the reservoir to replace any that leaks elsewhere. Your owners' manual would confirm. 'Curly' |

It has been leaking more than a year. Leaking is so small that it will not hurt timing belt...I just have to watch the operation of water pump by opening up the the upper timing belt cover so I can see it.. so I just leave it and I don't have to fix it right away...As long as radiator is full then it's ok for 3 or 4 days.... |

The choice is obviously yours, but a leaky water pump is doomed to cease eventually, and you won't get a warning from it (it is already giving you the best warning it can). When that bad boy ceases up, you could very well lose your entire engine. Not a gamble I'd personally be willing to take... |
