The SwirlRepair 4-cylinder rod is a direct replacement for the swirl operating rod of the following engines:
- Opel Vauxhall Holden Saab Cadillac Z19DTH (1.9 CDTI 16V, 110kW/150hp)
- Opel Vauxhall Holden Z19DTJ (1.9 CDTI 16V, 88kW/120hp)
- Fiat Alfa Romeo 939A2000 (1.9 Multijet / JTD(M) 16V, 100kW/136hp)
- Fiat Alfa Romeo 939A2000 (1.9 Multijet / JTD(M) 16V, 110kW/150hp)
- Fiat Alfa Romeo 939A2000 (1.9 Multijet / JTDM 16V, 125kW/170hp)
On these engines the swirl flaps are mostly OK. But the rod, which connects the swirl flaps, often falls off. The officially suggested repair is to replace the entire inlet manifold, and since half of the engine needs to be disassembled for this, the repair costs a fortune. In fact, the quote for a new manifold on an Opel Astra was the reason to develop SwirlRepair. Rather than replacing the intake manifold assembly including swirl flaps if just the operating rod is damaged, the rod can be replaced with SwirlRepair rod.
SwirlRepair uses bushings made from high quality brass and stainless steel. Inside the bushings there is an o-ring, which is located in a groove. The o-ring is made from temperature resistant material and works as a snap feature, thus keeping the bushing in place on the swirl flap’s ball joint. In addition, the SwirlRepair rod has some features that makes it fit and stay better.
By design the bushings sit more firmly on the ball joints and cannot tilt off as the standard plastic bushings do.
