I have a 1994 Isuzu pickup 2.3l. Over heating changed water pump and top hose and now the fan stops whene I put a rolled up magazine in it. But I also suspect the intake manifold gasket


oVER HEATING HAS
Many causes, not 2 like in your post over 10
and many symptoms not just 1. in most cases.
its not a gasket,
what makes you think its overheating
1: steam? go that?
2: engine power loss and ping.?
3: gauge told you ? in cluster, some lie , is yours fibbing (tests)
4: water blasting out the side fail tank (expansion tank>?)
5: leaks to ground>?
6: leaks to passengers toes, heater core or its hoses there leaking.
7: over heats only parked, ??????????????
8: fan dead. (that newspaper trick not a real test) many fans are RPM operated, not simple heat locked, as you think. we use RPM optical meter to test fans.
causes.: lots.
A: thermostat bad, they last about 6-7 years and die all do.
B; RAD cores blocked, we use a $15 IR thermal gun aimed at all tubes top/bottom, and find dead tube with no effort at all.
C: pump bad, no its ok , its new.
D; fan belt slips.
E: fan dead, but would not over heat moving fast. so....
F: junk and crud packing a/c front of RAD, condenser, or RAD.
G:engine block full of MUD, from zero service and flushes in 20 long year.
H: cam belt slipped now timing way off, and huge heat load from poorly burning fuel (and late)hits cylinders walls, x4 and huge heat load on the water jackets and with 1 weak item above, pushes said camel off the cliff, is sparking timing right if not cam slipped a 1minute test with any timing light every made.

and more, lots more,
not running 50% AF?
running pure water> omg

Make sure the cooling system is not plugged up, poor coolant flow can make your engine run hot, and a plugged heater core will not allow heat in the cabin in the winter.

A t hot temp subaru forester 1998


A car running hot can be of many causes. Thermostat can be checked by removing and place in boiling water thermostat should open when water reachs temp, hole in hoses hoses will expand when they become hot so a pinhole will open and beome lager when hoses heat, enginge needs flushing a lot of rust and dirt in anti freeze will cause the car not to run correctly, and water pump going bad. Also heater core however I would flush engine before replaceing heater core as it may become clogged.

No heat. Both hoses are hot at firewall connection. Replaced water pump and thermostat. Flushed coolant system twice, no restriction. Damper is free moving and servo motor works when temp change is...


As a mechanic i am leaning towards a bad heater core. The core translates the heat from the cooling system into hot air for the cabin. Often times if the core is bad it leaks. check under the carpet, be keen on the smell of the antifreez and keep an eye out for foggy windows. Good luck and i hope i was able to shed some light on the situation.

My cadillac is not giving me any hot air ,ive replaced the radiator, changed the thermostat, has a new water pump, where do istart to look.


Feel the 2 tubes at the firewall for the heater core. If they are not getting hot, the heater core needs to be flushed out or replaced. I had this problem with a 1990 Cadilac Deville, it was just a plugged up heater core.

Remember to install sealant after flushing out the system to prevent leaks.

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

I have a 96 sl saturn. takes half an hour for my car to reach running temp. When i start driving the engine cools down so far, to the point i have no hot air for my heater. I replaced the thermastat, i...


replace the thermostant again this time get a hotter temp thermostant and buy it from the dealer, the other thing is that these cars are known for the temp sensors being bad this would give you the false reading on the gauge but would not affect the heat, if its taaking a long time then i would replace the stant and this time or before replacing the stant i want you to flush out the heater core, remove the hoses from the heatercore and use a water hose to flush water through the heater core, a plugged core will not throw heat or will start to allow water to flow when it gets good and hot to flow through the retricted core due to rust and crud, try the flush first and then try a new temp sensor if the flush helps the heat, hope this is helpful good luck.

Dodge Ram 1500 - I have no heat. Will replacing the thermostat slove this? If so how do I replace the thermostat?


Hello, No! I'm assuming that the temp gauge is working in truck & you are not over heating. On the passenger side firewall check both hoses going to/from heater core. If both are not warm then it is probably a heating core plug. You will have to replace the heater core.
