slow engine coolant leak

slow engine coolant leak

Postby brianecamp [OP] » August 2nd 2012, 2:14pm

ok . . .

got a slow leak out of the radiator . . .

seepage along the plastic shroud which is behind it . ..

this is a less than two (2) year old system - i'm thinking it is a leak around a hose . ..

any ideas on how to access it ??

thanks

Let the engine cool down before trying this.

Take out the three bolts that secure the shroud to the radiator mount and pull the top of the shroud rearward. Make sure the water

level in the rad is right up to overflow. Hook up a pressure testor to the rad, and pump up the testor to 15#. Watch for any

leakage. These trucks rads have plastic end tanks, and the driver side tank, where the hottest water enters the rad, has a

history of being the fox in the henhouse IOW: subject to cracking. I had to replace one of ours, not too long ago, for just that reason.

Thank you for your timely reply UT !

I will definetly give it a try if necessary.

however, upon visual inspection with a flashlight, it appears as if i'm leaking around my lower oil cooling line seal . . .

I'm going to repair the obvious one first, then see if the system is tight.

thanks

ok . . .

looks like a loose hose clamp was the culprit . ..

excellent, i thought it might have been a crack where the lower oil cooler connector seets into the system . . .

Thanks again Uncle Bob . ..

darn it . . .

spoke to soon and had to change out the radiator . . .

went ok, but my top brake line didn't get insalled correctly and I shot about 3.5 quarts of oil onto the driveway . . .

then I overfilled with oil . . .

so, I changed it, cleaned up and now . . .

I am still trying to bleed the radiator system . . .

How may gallons of 50/50 goes into one of these things - I cant find the spec . . .

thank goodness my tranny lines were properly hooked up . . .

any thoughts ???

thanks

just exacly how tough is it to change out the oil pump in the event that I blew a seal, or weakened it ?

Thanks

There is nothing in the oil pump you could have hurt. If the engine is fine then you sure didn't hurt that oil pump.

In any event. It isn't tough changing the oil pump if you want to. I had mine out before. Starter in the way. trans dust cover. They say the exhaust should come off to get the pan out. Because the trans cover wont come out otherwise. And it in the way of the oil pan. But it all drops down enough you can reach in there to get it out.
