98 taco overheating checked basics now what

My 98 sr5 3.4 got hot in a very short drive i noiticed my heater wasnt getting hot i assumed thermostat got home and seen that my radiator was cracked i know very little but i assumed got hot because t-stat wasnt opening so it built pressure and cracked but if that were the case shouldnt it go into overflow plus pulled t- stat boiled it opened fine so if not the t-stat and and still blew cold air heater core i dont know my buddy said fan clutch but seems like it shouldn't be that bad if t-stat is still working and fan clutch is bad also my water pump is fairly new and i didnt see any leaks what is the prob

 

One is lack of punctuation making your post very hard to decipher. Let me see if I have this right.

You say it's overheating, based on what? Dash gauge?

You say the radiator is cracked. Assume now leaks? Have you replaced that?

Did you replace the T stat, or just test it and reinstall?

You say you have no heat in cab. Do you know if your airbox doors are working correctly, or have you proven there is no flow to the heater core?

Is/was the system losing coolant?

How long did you drive it 'hot'?

Has the radiator cap been replaced recently?

Does/did it overheat at slow in town speeds (fan dependent) or at hwy speeds (air flow dependent) ?

Have you checked the oil to see if there are signs of coolant (blown head gasket) ?

That's just some rudimentary questions. Give us all that info and then we can give suggestions on how to proceed.

 

I tend to smash everything i write togather my bad.this happened last night i let my truck warm up like i normally do say 10 minutes or so.I drove it for maybe 15 minutes my heater didnt get hot so i assumed t-stat.i got home when i noiticed it was hot not on red but just under i opened the hood and there is a crack in the radiator probably 3 inches long on front by the top top line.i already had a t-stat at home i pulled the old it worked.so no i havent replaced the radiator yet in my head and adviously i dont know much but if the t-stat was working and still blowing cool air its a diffrent problem.i never noitced any leaks up to now.havent replaced the radiator cap id say at leaste 3 year ago no water in the oil no apparent water pump leaks was replaced about 80 thousand ago as far as the air box is concerned im in the dark i have i have k&n intake hope thats what you are talking about i already feel lije an idiot so o well.my buddy says fan clutch just wanted a second opinion .

 

You say you have a cracked radiator.

That's pretty much your trucks problem.

Beyond that, you need 1 space behind every piece of punctuation and 2 spaces after every period. It will make your questions a ton easier to read.

 

grammar jokes aside it's quite possible you have a coolant passage clogged. New radiator and a good coolant sytem flush (clean) and get any nasty crap out of there. Your heater core (not very likely) could be at fault as well. I to, have a 98 PIMA sometimes. lol Good luck!

 

Thanks that helps a lot im trying to figure out why and what caused the crack in the first place but sounds like im just waisting my time and should just go get a new radiator and go from there

 

I flushed it didn't look like a blockage of any kind flowed fine

 

That's where I would start, I replaced one in my '98 I believe it cost around $100. Short term, you can JB weld it but that's a bandaid and not a cure.

If your radiator is cracked it won't hold pressure, so it won't cool correctly which will make you overheat eventually. It will also suck air back into the system and air lock your heater core. If it's actually cracked for whatever reason you can replace the entire cooling system and you'll have the same problem until you replace the radiator.

 

Yes. I agree with Indy. Go to radiatorbarn.com they have some good deals!

 

I refuse to read your horribly worded posts and recommend going to a mechanic and paying him.

Yep your right just pay sombody great idea probably would of just done that and not even wasted my time here dam your smart

 

Okay you found the most obvious cause of the overheating. Now change out the parts and see if the overheating continues.

 

New t-stat is in but still have a cracked radiator and im such a broke idiot cant go get one or a clutch fan wich my buddy swears is the problem but if it was just a fan clutch to begin with wouldn't my heater still have worked since i know my t-stat was working or am i over thinking a simple fix or what

 

If you cannot afford to get a new radiator jb weld the crack up for now. Keep in mind that's only a temporary fix

 

Your fan clutch might me starting to go tits up but it damn sure didnt crack your radiator! And beings its winter even if it dosent work at all id be willing to say it wouldnt cause an overheat anyway. Like said aboce replace radiator and go from there. Since air has been drawn into the system its prolly stuck in the heater core causing a no heat in cab situation. One thing to check for your no heat issue is to make sure your heater valve right in the middle of your fire wall in the engine bay up high by back of the hood is working smoothly and the cable is still attached. Thus can be checked by ooening hood and working it by hand. With that said my $$ is still on air in the core though, based on the radiator crack!!

 

If it was caused by air getting in the system the no heat why did it not work in the first place. I know could have been a stuck thermostat or a number of reasons just curious.
