#1.) Be very careful not to cross thread or strip oil cooler fittings. Do not over tighten them!!
#2.) Use plumber / Teflon tape when attaching threads for a proper seal.
#3.) If existing radiator had washers, replace with fresh ones.
#4.) For small leaks after installation , be sure to drive the vehicle at least 10 miles and re-inspect
Radiators do not come "defective" from the oil coolers.. This is a threaded area and most leaking occurs from improper installation.
If you are able to see into the cooler, you would check to see if the thread was possibly mis machined (no thread!!). We see only 1 or 2 of these a year. It would be the factory did not make the thread and just have an open cooler.
All other claims are not warranty situations, so we suggest trouble shooting prior to shipping an item back for claim.
You can always email close up pictures of your cooler to us for review, we can look to see if it is stripped or mis machined. (it is a distinguishable difference)
