Bostech has the EGR cooler problem solved. Most OEM coolers are failing due to cracking, which causes the water and exhaust to mix, or from becoming clogged with exhaust deposits. We have developed a process making the cooler much more reliable and maintenance free.
The Bostech design uses T304 stainless steel tubing to replace the turbulator design used inmost OEM coolers. The stainless steel tubing is tig welded to precision laser cut plates that are attached to the cooler housing. This will ensure the cooler will operate under the toughest of environments. This is a must for mass transit vehicles like school buses, ambulances, and wreckers/rollbacks.
2006 LBZ Note: It is important to check OE cooler for correct application. Some late 2006 LBZ trucks are equipped with a Tokyo Radiator Company EGR cooler #897358071. If you have this style you will need Bostech Part# EGR507 for 06-07 LLY.
