Question about 1986 Honda Prelude

1 Answer

I had a bunch of steam coming off the engine and coolant spilled all over the place and i found a hose with a hole so i replaced the hose and drove it for about 20 minutes and then it just started running hot again and steaming off the engine. i replaced the ect sensor about a month ago because it would idle out after driving for 10 minutes or so and it ran fine until now. no steam or fluid is coming out of the radiator. any clues?

The thermostat could be stuck closed.
The worst case is you over heated the engine to the point you could have internal damage to the engine . I would change the thermostat first. IF that does not work , I would take to a shop to have checked out.

Coolant leak, unknown location


There is a compression tester for the radiator. It is a special cap that fits on and you pump it up. This will allow you to look for the leak with the engine cold and not running.

You may have an issue with either dry rot of the rubber hoses or possibly a varmit got under the hood and chewed holes in hoses or wiring (happens all the time to vehicles stored for long periods of time).-Your fuel injection hoses up top pressurize to over 40 psi, so they need to be in good condition. If you are leaking fuel, do not drive it until you replace the leaking hoses, and driving an aluminum engine that is low or out of coolant is pretty much asking for disaster-better to get it towed and repaired.

Replacing thermostat


Easy to do at home. Requires the Coolant to be drained. My symptom was that the car took forever to warm up and the faster I drove the cooler the engine got which sucked in the winter.
1) Locate the Thermostat housing which is located at the front of the Engine, Passenger side, under the Air Conditioning compressor.
2) With the Cars engine cool, place a container under the engine where the Thermostat housing is located.
3) Loosen the Radiator hose clamp on the Housing, and pull off the hose from the housing. NOTE Coolant will start to gush out just make sure that the bucket or container is catching the coolant to avoid any spills. Removing the Coolant cap will make the coolant drain faster.
4) Remove the 2 bolts which hold the housing on the engine block. NOTE Coolant will start to gush out just make sure that the bucket or container is catching the coolant to avoid any spills.
5) remove the old thermostat, you will probably notice under inspection that there are some pieces of rubber seal missing on the valve which allow the coolant to bypass the valve, not good at all.
6) Replace the thermostat with one of equal temperature rating. Also replace the o-ring on the Housing while your at it, most replacement themostat kits have this included.
7) Make sure that the engine block surface where the housing sits is clean, and reinstall the Thermostat and Housing and Radiator Hose.
8) Fill the Coolant resevoir with GM approved Dexcool coolant.
9) Start the engine and check for leaks. Turn off the engine then top off the coolant again. Just be sure to remove the Coolant Resevoir CAP SLOWLY to equalize the pressure or you can get splashed with hot coolant BE CAREFUL!

My car started to overheat. I checked it out, and found a hole in a small radiator type hose. The hose is top left (facing the engine), is about 8" long, and comes from a black cylinder shaped object....


This one is not easy to tell without seeing the car. But, a logical guess would be that the water pump is starting to go bad and is leaking intermediatly. If you can pressure check the cooling system or have it done that should give you the answer.

Take it back to them. Most likely they spilled washer fluid or oil on a part that gets hot. Then when you drove the spill evaporated. They may have checked your antifreeze and improperly tightened the Radiator cap causing a leak.

Observe the temperature gauge for overheating. Some Lube places do more service than oil changes. You need to pressure test the Radiator for leaks. They could have simply overfilled the fluid.

Steam from under hood at idle.


My '97 CR-V would get hot enough at idle to evaporate rainwater on the hood, but I've never had steam come out from under the hood that wasn't one of these few solutions:

1. Coolant system leak in which the coolant is somehow being leaked or displaced onto a very hot engine component such as the exhaust manifold.

2. EGR (Exhaust Gas Recirculation) system failure in which fumes (and thus 'steam' or 'steam-like' discharge) are being introduced under the hood.

3. Exhaust leak near the engine.

4. Some (all?) vehicles cycle the A/C compressor whilst the selctor is in the DEFROST position. Is it possible that some condesate from the evaporator is spilling onto hot underhood engine parts?

5. Failure of supply hose to windwhield washer jets, usually caused by alcohol drying out the hose. Then, the washer fluid leaks on the hot engine, causing steam.

Check closely under there, I bet you find the problem.

Water leak coming from back of engine. 1998 BMW 318i 1.9


Hi, on these engines they have a plastic elbow at the back of the cylinder head that gat brittle and break inside the head, it may look ok but it would be a good place to start to look for a coolant leak as this is quite common. regards mark.

My 98 subaru forester is over heating


The head gasket may be a problem, but it may be simpler, if your thermostat is on the bottom of the engine.
If coolant came out when the thermostat was changed, there should be a screw, probably plastic, that goes into the radiator, or near the inlet hose, at the top. This screw is used to release steam when car overheats to restore the vaccum. Turn car on and let idle to overheating temperature. NOW PROTECT YOURSELF FROM GETTING A STEAM BURN. Turn the screw very slowly until steam starts to come out, don't unscrew all the way or you will loose a lot of coolant all over your engine. make sure the coolant resevore has enough coolant to get sucked back in to the engine or this will take longer. Continue this process until there is no steam coming out, I let mine go until a little liquid coolant starts to bubble out from around the screw. Tighten screw and keep a watch on your temp gage, you may have to do it a couple of times as the coolant forces the air pockets out of the line. If this doesn't solve your problem then I would say check the headgasket.
