over heating and about to going crazy

So this is the story of my car...... About nine months ago i picked up a 93 prelude with a f22a1 out of Texas..On the way home i found that the water pump was pissing coolant out off it. So i replaced the water pump and did the timing belt to fix to problems at the same time. After replacing the water pump the leak stopped and i could drive the car..

Well after a week of driving for some reason the car started over heating. Well the heater core hose popped on me so i replaced both hoses. After that i was able to drive my car for about three day and again over heating. So i replaced the thermostat thinking that could have been the problem. So after replacing the thermostat again i got to drive it for about two days and the over heating started again.

Come to find out i had a bad lower radiator hose. So i replaced both upper and lower radiator hoses. Well i did not even make it two hours before over heating again... Welcome come to find out my radiator fan was no longer working.. So we hook the radiator fan to run whine the car was turn on.

Well that worked for about a week before the over heating started again. I found running the fan all the time would not let the lower radiator hose get warm. So after replacing the relay and checking out all the wires we have come to find that the fan control box has gone out. So we put the radiator fan on a toggle. So to tested the gauge by letting the car almost over heat then we would turn the fan on.

Well after turning the fan on the temp gauge would go from red line over heating to running normal in about ten seconds. So to play it safe we replaced all the coolant temp sensors. So i had some extra money so went and got my tint done.. Well come to find out my lower tank on my radiator blew out sometime around dropping the car and them giving it back to me.. So now i have replaced the radiator,thermostat, upper/lower radiator hoses, heater core hoses,radiator cap and four coolant temp sensors. I am still having a over heating problems and really starting to get pissed off..

So we started thing maybe the head gasket had a small crack in it or something... So money I had a dye test and compression test done at a local shop i trust.So the test came back with almost perfect compression and no leaks from the head gasket.I know i am having problems with my lower radiator house getting warm, but my upper radiator house,radiator and radiator cap are getting hot.


So i am at a lose when it comes to this problem. I have order a new pod temp gauge to see if it well say i am over heating also. After I replace that I am at a loss what could be the problem.I could really use some help with the over heating problem..Something i find to be crazy about the over heating is most of the time when the sun is up the car will not over heat, but when the sun goes down i don't even get five minutes of driving before the gauge starts to jump.

To add on to that shopped drove my car around town before they did the dye test and my car would not over heat. They used a temp gun on the thermostat and upper/lower radiator hoses. The reading came back with 175 on the thermostat housing, lower radiator hose was 150 and upper was 155. So I am about to give up on this car and just take a loss if i can not find out what's making it over heat.

Re: over heating and about to going crazy

Did you bleed the cooling system? I know nothing about the f22s for sure, and am new to Hondas but on other engines there is a bleed valve that you need to utilize to get air out of the system. Check in a manual to see if you have one.

Re: over heating and about to going crazy

I do have one and i have been using it.. i spent over an hour and a half bleeding the coolant system today and it still over heated... I now have steam come from around the radiator. It started this morning when i remove the thermostat. I remove the thermostat to see if the car would over heat with out it..,

Come to shock it ran under normal running temp while i was drive, but again the steam has me worried. Some thing i don't understand is why my lower radiator hose got warm with out the thermostat on the car. I have replace the radiator cap with one from Honda to see it the steam could be coming from under the radiator cap. Well come to find out its not and i am back at a lose...

It's really pissed me off that with out the thermostat the lower radiator hose got warm and with it on the car the lower radiator hose stays ice cold and limp. I can have the radiator replaced for free and can replace the thermostat for free also... I am about 99% sure the temp gauge is reading right... So now what do i do now????


If my timing happen to be off could it cause my motor to over heat? Also what would be a sign that the water pump could have gone bad? The water pump was replace five months ago and has maybe 200 miles on it

Re: over heating and about to going crazy

Use a pressure tester to check the pressure on the cooling system, and test the radiator cap, even if it is a new one. Yes, mechanical timing could possibly have an effect on it, and I'm not sure how to tell if the water pump is bad unless you feel like popping off one of the radiator hoses and seeing if coolant sprays all over the place when you start the car. Wouldn't recommend that though.

Also, make sure you have a decent water:coolant ratio. Too much coolant can make it run hot. You can get the water density tester at AutoZone for $3.00.

Sensors and sending units could also be culprits.

With the thermostat, if you have it in and the lower radiator hose NEVER gets hot, but the top one does, that may indicate that the thermostat is not opening properly and needs to be replaced. You can test it by boiling some water on the stove and watch for it to open, or if you get one for free, go for it.

Ok as for the water pump i could see the coolant rushing thought the radiator when the thermostat was not on the car.. I know i am circulating coolant and a for water coolant ratio i am running 50/50. All four coolant senors have been replace and are working. I did a boil test on the thermostat last night and it opened and close with no problems.

I can do another pressure rest on the radiator, but this will make number three. The last two show no loss of pressure.. So right now the to do list is

1. pressure test
2. replace thermostat again.... This will make number 5
3 .have a buddy check time
4. ????????

Re: over heating and about to going crazy

If you've done all that, then you and I and a couple others I know of are in the same boat. I installed a secondary temperature gauge and put it where the ashtray goes so I can compare its readout to what the stock gauge shows, so I know when to worry or not.

So you had the same problem with the lower radiator hose being cold and limp?

Re: over heating and about to going crazy

pull the rad cap off while running if coolant gisers(rockets, comes out) while warm. if it is coming out like you have a vapor lock it will most likely be your head gasket i had a 90 doing his over heating but i found out it was the headgasket.

1run to operating temp
2 take off rad cap
3 look for coolant spitting out
4 its your head gasket

note you need to get your head pressure tested while its off i didnt and now i need a new head and headgaket not cheap... let me know if that helpes

Not that specific problem, but my car tells me it's overheating when in fact it is not, and I cannot determine why. I've performed just about every procedure and replaced just about every part related to an overheating problem with no fix.

Re: over heating and about to going crazy

I am going to have to replace the thermostat case now. One of the bolt hoses is stripped out and that could the reason my lower radiator hose could not build pressure. Thank to all the now Arkansas has had if i am lucky the new temp gauge will be in tomorrow or Monday.

even with a new temp gauge if i can not get pressure and heat to my lower radiator hose my thermostat will never open.. I am still at a lose how when i removed the thermostat my lower radiator house got warm with no pressure tho. Like i said i have to replace the thermostat case before i can even put coolant back into the car. I am i can find one in a junk hard for cheap.. I am to the point if i can not get the thermostat to open and pressure to the lower radiator hose i am just going to sell the car and save up for a 5th gen or another 4th gen that does not need as much work.. I am also thinking about buying a 4th gen with a bad mother and doing a h22a swap..


The only reason i will not keep this one and do the swap is because it needs a $250.00 radiator support bracket and upper/lower ball joints.. I am about $2000.00 into the car and if you want $2,650 if you add the rims and new tint on a $1,4000 car

^ video btw
So i didn't replace the thermostat case after all.. After looking the thermostat seal was hanging out just a little.. So i put the seal in the thermostat case with out the thermostat and drove it around town.,. As you can see the car did not over heat and ran great.

So why with the thermostat on the car can i not build pressure or heat on the lower radiator house?
