Vehicle
Buick Rendezvous
A tall crossover on GM's U-body minivan platform, the same vehicle underneath as the Pontiac Aztek, and sharing its powertrain with the Montana. The 3.4 V6 carries the family's intake manifold gasket problem and, on this platform particularly, a plastic coolant crossover elbow that fails abruptly — a sudden coolant loss with no prior symptom, which is worth knowing before chasing an overheating complaint into the head gasket. The 3.6 V6 fitted to the Ultra is a different, chain-driven engine with its own timing-stretch history. Versatrak all-wheel drive is a passive viscous coupling and sets no codes of its own.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
