thermostat in upside down.. [Confused]

How are the radiator hoses, they could be collapsing when they heat up? [Confused]

Just trying to throw some ideas out there

I would personally check the fan "Clutch". I had the same problem, before I owned Apex, with my car... Ran fine when it was on the freeway BUT once it got into stop and go traffic it overheated. We changed EVERYTHING.. thermostat, New Fluidyne Radiator, .. nothing helped until the fan clutch was replaced.

he has an electric fan

It's possible his fan is not generating enough RPMs to produce sufficient air flow.

is the electric fan that you have have a adjustable theromostat that has a knob on top of the fan? my car over heated once becuase i was fixing something and i accidently hit the knob and turned it to the right all the way so the fan would turn on when the temp would it 240* but i turn it all the way to the left and at litte tot eh right so it would turn on at 190* i have a 180* thermo,
 
Posted by migs66/92 (Member # 4811) on :
 
yeah i have an adjustable thermostat for the fan i got it to turn on at half ways in between the temp gauge and it was running fine for about 4 months then it started overheating bad specially in city driving so i lower it some more but it still overheating i just dont know what else to do ill problable just sell it
 
Posted by two-gun kid (Member # 5891) on :
 
turn the knob all the way to the left and then trn it back to the right just a little like 1/8 turn and that should cure the fan not turning on

My brother had the same problem when he put an electric fan, turned out to be one of the fuses. Check em out.
 
Posted by blind (Member # 3052) on :
 
is the fan running while the car is up to temp?

if not, just install a switch and bypass the temp sensor, so you can make it run when you want to.

radiator cap? Is it on a 66' or a 92'?
 
Posted by migs66/92 (Member # 4811) on :
 
its on the 92. radiator cap is new aswell the fan goes on when its supposed to.thing thats worrying me is i need this car to get to work and back and i dont wnat to pop the engine or mess up the heads, that shit expensive.any other ideas on what it could be guys???
 
Posted by Eddie510 (Member # 2354) on :
 
you checked if the thermistat was backwards?
 
Posted by two-gun kid (Member # 5891) on :
 
so does the fan turn on at all? if you want to make sure that it turns on at all, the thermo probe that you stick in to the radiator, has to wires that go into it, touch those to wires together and the fan should start, if it doesnt, check the fuses, and the wireing
 
Posted by migs66/92 (Member # 4811) on :
 
well thermostat is fine fan goes on perfectly i just fininshed checking it and im gonna try the coolant temperature sensor man this sucks i just took it out for a 2 mile drive and it overheated and started to leak antifreeze im getting really frustraded [Mad]
 
Posted by stangnut (Member # 5937) on :
 
go too the store an buy a cooler box with some ice or a super soaker, an when that bad boy heat's up ! better put a woopin two to it with you new arsonal!lol
 
Posted by SmokinLX (Member # 1684) on :
 
You should check to make sure fan is wired correctly and is pulling air thru the radiator instead of pushing.
 
Posted by Joooestang66 (Member # 2828) on :
 
Does the fan you bought flow enough? Does it pull enough cfm's through for your application? Basically is it meant for a 5.0 or is it a universal one you get from kragens? Also does it pull or push? It should pull but if you reversed the wiring it will push air to the front of the car instead of pulling air through the radiator. Also warm it up and compare the heater hose temps, if one is significantlly cooler than the other your heater core could be clogged. If thats the case by-pass it and see if it still runs hot.
 
Posted by a50sn95 (Member # 527) on :
 
Is there a temp guage on the car, or are you using the stock guage? If you've replaced all that and it still gets hot, then something else is wrong, like a blown head gasket.
What exactly does it do when it overheats?
Dennis
 
Posted by migs66/92 (Member # 4811) on :
 
well the fan is pushing air i cant remember how much cfm it pushes i did have it pulling air for a wgile but it got to hot I went ahead and reversed it to pushing air and it was cooling good for about 4 months. im gonna go check the heater hoses right now ill post back about results in a bit thanks man.
it also has the stock temp gauge. when im driving the car it seems the temperature seems to go up when the car is under load not so much as when im sitting at a red light
 
Posted by Joooestang66 (Member # 2828) on :
 
A pic would help. Is the fan installed in front of the radiator or the back? Is it in the engine bay? Does it have a shroud?
 
Posted by migs66/92 (Member # 4811) on :
 
fan is behind radiator in the engine bay it also does have the shroud on. how can i check to see if it could be a head gasket problem???

Head gasket problem, you would see milky oil(check dipstick) you would see white steam/"smoke" coming out of tailpipes and you could usually smell it if you get next to tailpipes.
 
Posted by blind (Member # 3052) on :
 
if the fan is behind the radiator on the engine side it needs to be pulling air through the radiator towards the engine.

does the fan run constantly while the car is running?

When the temp control relay died on my black magic fan the fan would click on, then off after 5 seconds, then trip on again later, but it wouldn't stay running and the car would overheat.

my solution was to wire a switch to the fan to bypass the temp sensor, so I just switched the fan on when it was up to temp and turned it off if it was running too cold (like on freeway).
 
Posted by migs66/92 (Member # 4811) on :
 
well the fan runs constantly when its supposed to so i really dont think the fan could be the problem im gonna try and installing the fan on the opposite side and flip the wiring.
I ahve been checking the oil and the iol shows no sign of having wtaer in it it also does not throw any smoke of any color. i have noticed theres kindda of a antifreeze burning or something like that when im at a stop light could that mean anything?im just running out of options i already put in another thermostat in.reflushed the radiator checked just about everything i could i just dont know what else to do!!is there a teast i could run to find out if its the head gasket???
 
Posted by h8louzn (Member # 1075) on :
 
Yes there is and most radiator shops will do it for like 30.00..
What temp thermostat do you use?

If you smell antifreeze there is more than likely and leak..

If there is a small leak the cooling system can't hold the pressure and will boil over a a lower temp..

Also make sure you put the fan behind the radiator in the engine bay and wire it to pull air not push...
It needs to pull...
If you put the fan in front of the rad. you will cut down the airflow while driving causing another problem..

Hope this helps..
Eddie

If it was in backwards it would not get hot at all!!
 
Posted by migs66/92 (Member # 4811) on :
 
hey thanks eddie i appreciate your help
the thermostat im running is a 190*
there are no visible leaks that i can see also i only smell antifreeze when the car is really hot and before it boils over im gonna go take it to a radiator shop and see if they can do a test on it thanks man

have you tried bypassing the heater core like suggested before?
 
Posted by BCINGUU (Member # 2397) on :
 
No electric fan will produce as much CFM as a mechanical fan. Take it out, put the stock shroud and fan back in, and use a Heavy Duty fan clutch which you can buy at any auto parts store.

how do i do that???
 
Posted by migs66/92 (Member # 4811) on :
 
i gotta go and get a new clutch fan for it. those damm things are expensive [Eek!]
 
Posted by blind (Member # 3052) on :
 
follow the black tubes on the intake towards the firewall, at the firewall you'll see it splits into 2 rubber hoses, take them both off and then loop the larger diameter of the two back so that it connects both of the metal tubes that run along the intake, that will bypass your heatercore.

if the heatercore is blown your whole system wont hold pressure, if you can smell coolant you have a leak somewhere and no matter if you have a turbine powered fan cooling off the motor it will overheat if you can't get it to hold pressure.
 
Posted by migs66/92 (Member # 4811) on :
 
well it turns out to be the damm head gaskets so here i go im gonna try and do it myself any suggestions or tips on doing em??
 
Posted by blind (Member # 3052) on :
 
I'd suggest putting better heads on then come off [burnout]
 
Posted by migs66/92 (Member # 4811) on :
 
yeah i would put better heads on but i not able to spend that kind of cash on that right now i have another ? when i took the heads off there all kind of burnt shit on the pistons whats the best way of cleaning that shit off with out damaging the piston walls or with out getting shit in the piston? my neigbor said to use carb cleaner and use a blow gun and blow all the shit out of it.I was wondering if thats a good idea.
 
Posted by blind (Member # 3052) on :
 
that would work, but carb cleaner wont do much.

best way is with a wire wheel attachment for a drill, then clean it off really good with rubbing alchohol or carb cleaner than blow off with air compressor
 
Posted by migs66/92 (Member # 4811) on :
 
kool thanks blind i really appreciate your help man
 
Posted by Hungry Hippo (Member # 537) on :
 
after you do that, clean the cylinder walls with wd40. also make sure the block and head surfaces are clean and flat
 
Posted by migs66/92 (Member # 4811) on :
 
should i do the same to the bottom of the heads? the valves look like shit too.
does anyone what the rates are for redoing heads just a regular head rebuild or maybe just new valves and guides?
 
Posted by migs66/92 (Member # 4811) on :
 
what kindda permatex product should i use on the head gasket? should i use copper spray a gasket high temp sealant, or use ultra black hi-temp rtv silicone gasket maker for the head gasket???or should i use anything in between the head gasket and block at all????
