Question about 1995 Subaru Impreza

1 Answer

Overheating hi i have a 95 WRX with an overheating problem. The radiator had a leak but only under pressure so i changed the rad, prior to changing the rad the temp was going up with loss of water and cold air would come from the heater when on full heat then it would go to hot and bring the temp down. Prior to changing the rad it stopped giving heat from the heater completly. Having changed the rad and filled up it is still overheating, the top hose feels very pressurised and warm but the bottom hose is cold but pressurised and the heater will only blow out cold air. I have purged the system and re filled up assuming a possible air pocket however this didnt work. I dont think its the pump as i cant hear it. i am thinking its probably the thermastat stuck closed? or it still has an air pocket and needs purging in a different way? i am presuming that the thermastat is housed at the end of the top hose? can anyone help many thanks in anticipation. Mark

    hi i have the same problem on my 1993 model impreza as markyb 1. I have put a new water pump on, a new thermostat and after being told by 2 different mechanics it was an air lock, i bled the system about 4 times and i still have the same problem. please please help! would it be my head gasket?

    there is no steam when engine is warm and no water in the oil.

    ok i tried a new thermostat then a new header tank as the previous 1 had a split. purged the system and it seemed to be holding temp as normal but still no hot air from heater so i decided to give it a little drive, 50 yards down the road bang! steam everywhere got it back opened bonnet to see a split top hose which when running the engine up to temp felt like it was highly pressurised - any ideas?

    try running the engine and when its already hot, turn on your ac see if the temp would go down, if it is, your fan or your temperature sender is not working properly.

I have a 2005 Suzuki Aerio that keeps on overheating change the thermostat change the radiator but a hose is building pressure causing it to burst

bad hoses.!! heck they are 10 years old, none last for ever.
a hose that fails is a bad hose. but some old hoses can be
pushed of the edge, sure, but hose is bad never the less.
is the rad cap new,? (do that first) use correct cap, pressure rating
never over 14psi.
my guess is you have venting? (name all overheating facts, SIGNS)
arethere signs oif steam and oil and carbon in the rad side tank or at filler hole (cold checked only)
if yes, that can be bad head gasket or far worse.
get the rad pressure checked (hand pump) leak down test.
then check the rad for exhaust gasses. blue/green tester.

does it only overheat parked.? when?
if it stays cool moving that means the fan is dead, parked.
the natural pressure is 12-14psi regulated by the cap.

you need to do tests first. not change parts.
are you going to replace all parts only to find a warped head.?
i cant hear engine run, nor do rational analysis.
nor see it mess up, or when and how bad. not me. im blind.
asking net bunny's (blind) how to fix this is over the top.
why not get the car serviced by a pro that has all those tools.
(at least 3 tools)
compression tester.
rad leak down finds leaks and if block head cracked or head gasket blown.
green/blue rad cap tester. (exhaust leaks)
a pryo IR heat gun to measure for hot points. (checks cores easy)

I have a 2008 Subaru WRX that leaks water inside every time it rains. The water also pools somewhere in the body of the car creating a washing machine sound when I drive. Anyone hear of anything like...

hi i have had this problem before it turned out to be the interior heater radiator coil under the dash it had a hole in it causing water to pool in the car and causing the heater to **** in air causing the heater to sound like you mentioned i would give that a check first, the radiator is under the dash either on the passenger side or near the middle as some models changed position

My radiator was changed and the thermastat but my car is still over heating, why could that be? nohoses r broken.

sounds like a head gasket blown, when engine is cold, remove rad cap and make sure rad is full, start engine and see if bubbles are pushed out of the rad filler spout, a blown head gasket will pressure up your coolant system, was the rad changed because of overheating, do you have the thermostat installed wrong? the sensor side toward engine. if head gasket is ok, next you could check your rad cap, is the gasket ok? can you check if it holds the required pressure. might need replacing. also if you could pressure test the coolant system and see if it holds.

You could just be burning it up. Do you have accesive white smoky exhaust?
Have you filled radiator completely. Fill completely once while vehicle is running, burp upper radiator hose while adding. Then wait 10 minutes and the coolant level should drop in radiator as it will flow into engine block. This is where you want to fill the system again, and put the cap on.

Car overheated alot of water leaking out the

First find exactly where the water comes from.
broken hose or hole in radiator - if no leaks here then :-
broken / loose drive belt to water pump - sign is no heat to internal heater
thermostat stuck - heats up and overheats quickly. water from exits rad cap area
also check radiator cap - should be sprung to contain water under pressure, usually these are very reliable

check oil filler cap [inside of] - should be oily and grey/black If it has a covering of what looks like soft brown aireated jelly then possibly hear gasket or other internal engine leak between water & oil ways. The excess pressure from engine will force water out of rad cap area . A compression test with variable readings for between cylinders will confirm this. Hope its not this. It's expensive

1994 Honda Civic LX\overheating within 2 mile drive

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Low coolant

No 1, replace the rad cap.
You also need to have the cooling system leak tested, for carbon monoxide ingress, the tester fluid will change color, indicating possible leaking head gasket.
The cooling system needs pressure testing, with a test pump.
This will normally show up a leak.
Check under carpets, for heater matrix leak.
Good Luck !

Don´t forget to give a fixYa rating Please !
