Topic: blower blow cold and over heating?

[konarider1993]

I noticed on way home from work my heat was blowing cold then when i was coming home from buying 36 inch swampers started over heating. Is it a common problem with the heat blowing cold or do i have to figure it out on my own. thanks guys

well have you checked anything?
thermostat could be stuck,
got coolent?
waterpump working?

Did your heater work before you put on the swampers? Have you checked the coolent level,the thermostat,fan clutch,water pump so on and on.Check you rig out like your just about to head out to the trail and you'll probably find whats wrong with your cooling system,If not you can take those items off the list of what could be causing the over heat issue with your truck.

coolant is low or the water pump is not working

worst case blown hg does it have anyother symptoms? idle rough coolant in oil sweet smelling exhaust?

[konarider1993 [OP]]

I let it cool down and the next morning my brand new radiator was missing a gallon of coolant and the reservoir was pretty low. I filled up both (let it run while i was filling radiator) and ran and drove it for a day and the coolant reservoir had coolant coming out of the overflow till my radiator is low and it starts boiling and i over heat.

did you burp it

[ajordan1975]

I have the same problem from time to time. New radiator, fan clutch, thermostat, and water pump. I have no idea what it could be.......

pressure test the coolant system while it is cold then while it is warm. Be careful popping the cap when its hot/warm I only refill coolant systems with a burper funnel or park the truck on an incline over 15 degrees and fill it up/let it warm up and top off. You might have a blown hg or cracked head.... why the new radiator? just a leaky one or did it totally go out and engine overheated?

start cold w radiator cap open, fill up ,let warm for bout 2 min bubbles should creep up,
bubbles stop ,cap back on .40 /60 coolent
x2 on checking head gasket

i put a new thermostat in and it seems to be running fine on the short test drive i took but now i have white sweet smeeling exhaust

coolant is low or the water pump is not working

Or you have symptoms from either...Blown HG for example. Check your plugs or your oil on dipstick. Compression test while you are there. However this is not always accurate to diagnose a blown head gasket. If it is a coolant issue then it is either leaking to the outside and you'll have coolant on the ground or leaking into the cylinder where you will have rough idle, possibly a white tipped spark plug, coolant in your engine oil (looks like chocolate milk on the dip stick)

Bottomline, no coolant through your heater core (low level-leaking out through HG or through any other cooling system component, stuck thermostat, bad pump)or the coolant isnt hot (not warmed up(thermostat has been removed)). If youve replaced your thermostat and checked your coolant level and made sure the heater core isnt leaking then I would chase 2 things

1. Water pump. does the system circulate or build pressure? If so then your pump is probably good. Plus you will heat up pretty quickly on drives
2. You have the ever so common blown HG...From your latest post, this seems like the culprit...

There arent many components to trouble shoot in cooling systems...radiator, thermostat, water pump, heater core, block channels. It is a circle just chase the most common problems first...Unfortunately a blown HG is almost as common as a stuck thermostat.

Let us know how you make out

yep hg is toast check your oil quick if it has collant in it drain oil and dont drive.  the coolant will rust your crank and take out berings

what is burping and a burp funnel?

Its a funnel that you put on the radiator where the cap goes, you dont really need one.
When you burp it, you leave the cap off, so the air that is the system has a place to go after the t stat opens up
If there is air at the t stat, it might not allow it open , with the cap on

[yotaneck13]

or hydro lock it

[twistedtoy92]

Just use a burp funnel, it puts coolant above the highest point in the coolant system which puts more pressure on the system to force the air out. Air trapped in places such as the head or block passages will create hot spots and potentially crack expensive components... Believe me, the funnels are well worth the money!

o ok i just didnt know what that was called

[79yota4x]

its his radiator because he drilled a hole threw his other one he didnt have an over heating problems before he put the shi**y plastic oriellys radiator in it.
