Question about 1993 Honda Civic 4 Door

1 Answer

Overheating I have changed the thermostat twice, upper and lower hoses, installed a new rad, a new waterpump. I am losing fluid, and the temp gage jump to high and then lowers itself to normal ,then jumps back to hot and fluctuates between normal and hot. The rad fans comes on then shutoff and then comes back on.

    the water leaks after 5 miles. no water in the oil. the head gasket is bad. a shop told me that this is a sleeved engine and you must mill the block to get it to seal again. needless to say, that means an engine replecement. can you mill the head and get a new head gaskest to seal without pulling the engine ?

    thanks,

If you are losing fluid and you do not see it on the floor it is going either of two places. In the oil or out the tailpipe. The fluctuations you see and the fan going on and off is the result of low fluid levels. Sometimes the sensors are touching the fluid and sometimes it is not. It sounds like the head gasket is bad. Check the oil filler cap and dipstick for white milky creamy stuff. If you see it the water is going into the oil and is destroying the lubricating properties of the oil and will destroy the motor if not taken care of. Change the oil very often until it is fixed. If there is no milky stuff it is likely leaking to the exhaust which is not as bad but still needs to be fixed. If you pressure test the radiator system it will likely loose pressure slowly if the gasket is bad.

Remove the thermostat temporarily just for a diagnostic strategy. Put the thermostat housing back on with a new gasket and then drive it for a time to confirm that it is no longer doing that same thing. You will be running too cool to leave the thermostat out and you will have little or no heat. I just want to know if removing the stat helps before I continue. let me know.

I have a 2007 Buick 3.8 ltr engine and the heat is higher than ever in the interior. But the gage says cold the hoses are not that hot although the upper rad hose is a little warmer than the bottom hose


Check that you are getting fluid flowing through the system. Obviously make sure system is full. Check the return hose (from engine to radiator; usually the upper) is firm when hot and running and input hose (from radiator to engine; usually the lower) is firm and hot. If out from the radiator is but return to the radiator is not then you probably have a flow problem. Make sure your water pump is turning (and pumping) and check that your thermostat is not frozen closed. A frozen closed thermostat can stop fluid flow causing your engine to overheat and do serious damage while your temperature gauge reads low temp because there is no fluid getting to it to make it sense high temp. Frozen thermostats cause head gaskets to blow and engines to seize. When I replace mine I spend a few extra dollars and get the over temp protected thermostat because they lock open if the engine overheats rather than seizing and jamming closed. I'd rather change the thermostat than blow a motor or blow my radiator cans off. ;-) Good luck and I hope this helps you out.

I own a impala 2003 and i would like to know how to change the thermostat on it.The motor is a 3.4 liters


Drain radiator. Remove upper rad hose from thermostat housing. Disconnect air intake hose from throttle body. Remove throttle body from upper intake manifold, disconnecting the 2 rubber hoses to the heater line. You may also need to disconnect the fuel line. Remove the exhaust crossover heat shield and loosen the crossover pipe from both exhaust manifolds but don't remove crossover completely. You should have access to the 2 thermostat housing bolts, remove upper bolt but just loosen the lower one about a half inch. Pull the housing out and up from the intake manifold to access the thermostat. Clean the mating surfaces with a gasket remover. replace thermostat, apply a light coating of rtv sealant to both sides of the new gasket. Replace thermostat housing with the gasket to the intake manifold. Apply some rtv to the bolt threads before reattaching housing. Tighten bolts snugly but do not over tighten. Tighten exhaust crossover and reattach the heat shield. Install throttle body attaching the 2 little hoses at the bottom, its a good time to replace these hoses and clamps. Depending on the condition of the throttle body gasket you may need to replace it also. Reconnect the fuel line (if disconnected) Reconnect air intake hose to throttle body. Reattach the upper rad hose to housing. Fill rad with coolant 50/50 mix with water (make sure to use the same type antifreeze that is in the system, they say you can mix green with red but I wouldn't recommend) Leave rad cap off start the car and let it warm up until you can see the coolant circulating and ad coolant as necessary until full. Now there is going to be some air in the system that you need to bleed out. There are 2 bleeders on this system, 1 is on the top of the thermostat housing, and the other is on the metal heater line on top of the water pump (the one that goes across the front of the engine and around under the throttle body that the two little hoses attach to) Bleed the one on the housing first (its the lower one) open it until fluid comes out then tighten it. Then move to the 1 on the heater line(above water pump) loosen it until fluid comes out the re-tighten. Fill recovery tank to fill line replace the rad cap and take it for a ride, watching the temp gage closely. If the temp goes higher than normal than there is probably more air in the system. you'll have to bleed it again.
This is a very labor intensive procedure and I do recommend buying or checking a service manual out from your local library. I've done these in the past and to be honest I just have the dealer do it now. A system flush and thermostat replacement was around $230 the last time I had it done, but it comes with a warranty. And you wont have to rent or buy a fuel line disconnect tool if you end up having to disconnect it. These are the hardest thermostats I've ever replaced.

First check that the thermostat was installed correctly. It will not work properly if it was installed upside down. If this is the original radiator, it most likely is plugged up with deposits and corrosion. It needs to be replaced with a new one.
