Well, did a timing chain job on my truck a month and a half ago. Been having a problem with it.

After running for 10 mins or so it starts steaming out from the hood. Also the temperature gauge goes up into the red.

I opened the hood and I can't pinpoint where it's coming from. I have tried replacing the thermostat and burping the system (not sure if I did it right or long enough). Also there is no heat from heater.

Everything was just fine before the timing chain broke. Heat worked fine, no steaming. Also, I checked the oil and radiator fluid, no chocolate milkshake. Also it doesn't smoke out of the exhaust. Not sure what the deal is, I have searched it, can't find anything similar. Any ideas?

Thanks!

Have you started it with the hood open and watched as it heated up to check for leaks? Is your radiator clogged? flushed the coolant system? Started it cold with the radiator cap off to check if coolant is pushing through the system? When you burped the system did you do it right? I.E. with the heat on and the truck on an incline? Lots of stuff to check hear just start eliminating problems as you go. Degrease the engine and let it dry. When dry start it up and start searching for leaks. If there's steam there's most likely a leak some were. Do a quick search on 22re coolant hoses and find some pics of them so you know what you're looking for. When the timing chain broke was it a "big deal" as in did it rattle around enough to break any thing like the head or the cover. Did you replace the cover? Maybe you should outline what you did when you did the timing job for us to get a better picture.

You need to start the engine and watch for any signs of steam, once you start seeing the steam appear try and locate the source. It could be anything from a pin hole in the radiator or radiator hose, to a bad water pump or gasket on the timming cover.

No, rattled a little before it broke. I didn't replace timing chain cover. Barely any wear. Plus I don't think that would be the source of the problem in the first place. There would be coolant in my oil if it did wear enough right?
Flushed coolant system.
When I burped the system I had the heat on all the way, on an incline with the front up, cap off, and poured coolant in until full.

Well it seems as though you covered you bases for the install and burping the system. My best guess is you have a pinhole leak some were like myyota said. Pop your hood and fire it up to see where the leak is coming from. I found that if i can't see it from the top try the bottom. Look for puddles on the ground they might give you some direction. To give you an idea there are two hoses from the radiator and two from the intake. one from the water pump to the block. two to the fire wall that leads to the heater core. Might be more but those are the ones i can think of off hand. Is your radiator cap good?

dwnhiller93

I thought to myself whether or not its good or not. Who knows how old it is, might as well replace it. It could be letting air in maybe? Not sure though. Tomorrow after school I will try the hoses you mentioned. Water pump and timing chain cover aren't leaking for sure though.

Keep us posted. Glad to help.

sounds like the heater hose going to the core might be collapsing. you said the heater is no longer working, could be that the supply hose to the heater core has deteriorated so that the inner layer is blocking the flow of coolant and maybe a pinhole leak under pressure. Just my 2 cents worth

dwnhiller93

Well, just got inside. I put the overflow tank on (didn't put it back on after the tchain install, slipped my mind...) so that might be the reason I keep getting air into my coolant system? Not sure how it all works but that could be the source to my problem.
Also, found a small leak on the top of my radiator. Thats not where the steam was coming from, but maybe thats another source of air getting in there. Sealed it up, will try burping the system again tomorrow.
Please let me know how the whole overflow tank works, tried searching, haven't found anything. Would not running one be where my problem was? Thanks guys.

The overflow works by catching coolant that the radiator cap lets by as the engine warms up and the coolant expands. After you turn the engine off and as the coolant cools and contracts, the radiator cap will let the radiator suck coolant out of the overflow and back into the radiator thus keeping it full.

abecedarian

Have you tried running it without the t-stat to see how it goes?

dwnhiller93

so its safe to say air would get into my system with out the overflow tank?

dwnhiller93

and yes I have

abecedarian

So, get's hot, no heat from heater... and does this even without the t-stat installed?
... sounds like water pump to me.

Barring an issue with the heater core and hoses connected to it, the water pump should at least circulate coolant through the heater core resulting in some heat from the heater.

dwnhiller93

Could be water pump. Just trying to get all possibilities out of the way before replacing water pump. But answer still unanswered. Could the NO overflow tank be the cause of air getting into the system?

abecedarian

Yep. NO overflow could cause air to get in the system.

dwnhiller93

thank you. I will let you know how everything goes.
