Every 'cheap' radiator I have bought to save a few bucks ended up failing and got replaced by a more expensive one. In the end, it usually means you spend more than if you do it right the first time. My suggestion is either OEM or from a reputable manufacturer of after market radiators...though they are typically more expensive than OEM replacements.

 

Might want to check thermostat gasket for leakage if there's coolant on top of engine.Or the hose connections that go to the the t-stat. Sounds like more than one leak.

 

Source one locally. When you figure in shipping, buying online isn't going to save you anything.

Just go for the OE version. The radiators failure points are NOT the mounting tabs.

Once you have your new radiator installed, beg/borrow/rent a cooling system pressure tester from the local parts store. Make sure your cooling system is full, and then put some pressure on it. Sometimes, the leaks can be fun to find........ Some favorite spots are: Timing cover, right at the top.... Bypass hose, under the a/c compressor.... damn near impossible to see...... freeze plugs behind the engine mounts..... and the freeze plugs on the back side of the engine block. (gotta pull the motor, or drop the trans to change those.)

 

Many winters ago I fooled around with a slow drip at corner of radiator for couple weeks, then GOOOSh! Then it was an emergency fix and did they see me coming. 600.00 OE
complete with a 7lb radiator cap.

 

Anything over $200 range is too much.

+1 on sourcing locally.

 

maybe, maybe not.
it'll be hard to beat $91, no tax and free shipping.

if you have an automatic trans, be sure your new radiator has the built in trans cooler.

You should perform a thorough flush of the engine block and the heater core as well.

 

i drained the radiator...filled it...ran the truck until it got up to normal temp with the heat on. drained it again. and repeated again and water was coming out clear.
does that cover it?
