water pump/coolant problem and questions....please reply

OK...here is my situation.... about a week ago I noticed I was leaking anitfreeze (green)...figuered it was no big deal, no low coolant light and the leak wasn't that bad.... two three days ago saw leak getting worse...looked around, checked the hoses, and found my waterpump leaking. So like an idiot I figured keep 2 3 gallons antifreeze in truck and watch the temp gauge and low coolant light like a hawk, The next day I ordered ssdiesel HO waterpump, well I got the pump today and will install tommorow but now I'm hearing a slight overheating ping (you know that kind of sound when your running hot (but I never let the truck run over 210F.....Question..when your waterpump is leaking does that mean its not circulating coolant properly? or does it mean your just leaking and if you add coolant and watch your temp you'll be ok? also i noticed a little white smoke at idle ( in the dark with someones headlights pointed at my rear).... so tommorow do I just install this pump or do i check for a blown headgasket or some other problem? Also these pumps are a little tricky to put in...someone said you have to take the timing cover off to get to the bolts...and if so do you need to replace the timing cover gasket? ssdiesel sent me the gasket for the pump but didn't even mention or make available a timing cover gasket..... Can you believe this...All this trouble over a stupid waterpump and me (the IDIOT).... am I SCREWED or do I stand a chance..........Louis

This will give you an idea of what a waterpump and crossover installation involves......

put a mirror over your exhaust tip to see if the gas coming out fogs it up. If not, then check your upper radiator hose upon a cold startup. If it's not hard, then I would not get too excited. Others here will be able to give you a better diagnostic tip on that, though.

Your cooling system is designed to operate under proper pressure. The leaking pump may be allowing the pressure to be too low. I've seen this with a leaky radiator before, but not because of a leaky pump. Does yours always operate at 210, or just when towing? If it's always, then I'd suggest a new OEM t-stat to start with. Then see what happens after that.

I can't help with the gasket thing, because I don't remember. sorry.

Someone will chime in shortly, though.

I did the cooling upgrade not long ago. That kit including the timing chain cover gasket . The cover and pump actually come off in one unit. Which is good because then you can inspect your timing chain. If your pump didn't come with the timing chain cover, I would email Walt at SSDiesel Supply and ask about it.

About 200 fewer exclamation points would have worked just as well. I'm just before changing my water pump so you are about a week too soon for my hands-on advice. Plus my 6.5 is in a van and not a truck, so it will be different in many ways (harder for me I think).

However, here's where I can give some advice. Don't automatically rule out the dealer to change your water pump. I got estimates from a dealer and two independent garages and they were all about the same at $550-$650. In fact the dealer gave me the lowest of the three estimates.

As for plate removal, take a look at the exploded drawing below. The mounting bolt(s) labeled as #98 clearly enter the water pump from the back of the plate, requiring the removal of the plate to get the water pump off. But on the plus side it's only six more bolts to get the plate off.

So yes, you will need a new gasket for the plate as well as the gasket that came with the water pump.

EDIT: Local GM dealer told me there is no gasket for the timing chain cover - just use an automotive engine sealant. In the drawing below, "A" points to the 3 beads of sealer. Sealer is GM Part 1052357.

You don't need the gasket....I used gasket maker rated for oil and water....has worked fine so far....

IIRC OEM doesn't have a gasket behind the timing cover, just like the valve covers, there is a aftermarket gasket but a thin layer of good silicone will work fine on a CLEAN surface. (I think i used the blue stuff on mine?)

this is all great info, so far I got it apart.....may get lucky and a local auto parts store may have the gasket then put it back together and pray for my head gasket or heads or whatever else can go wrong when you drive a leaking water pump around a couple of days..... just don't know why I feel like i have a miss now?.....Just can't understand if I never ran the truck really hot why something else would go?.....I'll keep you posted...thanks...Louis

As far as the over heating worry, I regularly get my burb up to 230-235° towing in the mountains and it has 223,000 miles on it, havn't blown a head yet.
