Need support. Just found out my radiator is leaking

How do you know what cooling systems you have all I see is two lines coming from the radiator going to the bottom of the engine block I don’t know if it’s a oil cooler or a trans cooler

If it has a trans cooler? the 2 lines run from the drivers side of the tranny to the passenger side of the radiator.
If it has an engine oil cooler too? there are 2 lines that run from the engine block just above the oil filter to the drivers side of the radiator.
RPO code in the glove box tell the tale too.

So is that a transmission cooler then? Right to
The radiator ?

Yes, those hard lines are for the transmission.

 

[iboughtatahoe23]

Yes, those hard lines are for the transmission.

so when ordering the new radiator do i just order a normal one or?

 

[DodDel5-3-6L80e]

Yes, with the same number of ports, and you should be good to go.

 

[iboughtatahoe23]

Ports… so just count any tube or hose? Trans line included

Yes, with the same number of ports, and you should be good to go.

 

[DodDel5-3-6L80e]

Yes. Every hose and line. Match it with your year and model but verify number of ports.

You really should pressure test the system, many parts stores loan them for free (but for the money a worthwhile purchase) They do not cause damage to the cooling system (think about it, 10 psi from a tester is lower than normal operating pressure) and you can HEAR the leaks without the engine noise and without burning yourself on scalding hot block. Also, look at the coolant and oil fluids to make sure they aren’t being mixed together.

I’m taking it to a shop today he’s gonna find the leak, not to familiar with pressure tests.
