Engine Timing Belt Guide for 1991-1996 Dodge Stealth
Everything you need to know about choosing the right timing belt and avoiding catastrophic engine failure in your DOHC or SOHC Stealth.
- The DOHC Dodge Stealth has an interference engine; a timing belt failure will cause catastrophic damage.
- Replace the timing belt, water pump, tensioner, and pulleys as a complete kit every 60,000 miles or 5-7 years.
- Gates is a highly recommended aftermarket brand, but always use an OEM Mitsubishi hydraulic tensioner for best results.
- This is a complex and difficult job; professional installation is recommended for most owners.
Understanding the Dodge Stealth Timing Belt
The timing belt is one of the most important maintenance items on your 1991-1996 Dodge Stealth. Its job is to keep the top half of your engine (camshafts, valves) in perfect time with the bottom half (crankshaft, pistons). The V6 engines in the DOHC Stealth models (ES, R/T, and R/T Turbo) are known as "interference" engines. This means that if the timing belt breaks or slips, the pistons will hit the valves, causing catastrophic and costly engine damage. The base model's SOHC engine is a non-interference design, which means a belt failure won't destroy the engine, but the car will still stall and leave you stranded.
Interference Engine Warning
All DOHC (Dual Overhead Cam) Dodge Stealth models have interference engines. A timing belt failure on these cars will lead to bent valves and major engine repair bills. Do not neglect the replacement interval. Driving with a suspected timing belt problem is not recommended.
Symptoms of a Failing Timing Belt
A timing belt can fail without any warning, but sometimes there are signs. If you notice any of these symptoms, you should have your belt inspected immediately.
- Engine Running Poorly: If the belt has stretched or jumped a tooth, the engine timing will be off, causing rough running, loss of power, and likely a check engine light.
- Ticking or Scraping Noises: A ticking noise from the front of the engine can indicate a problem with the belt or, more commonly, the hydraulic tensioner. A scraping sound could mean the belt is loose and rubbing against the timing covers.
- Engine Will Not Start: If the belt has broken completely, the engine will crank but will not start. You should not continue to crank the engine, as this can cause further damage in a DOHC model.
Choosing the Right Aftermarket Timing Belt
When it's time for a replacement, you have several good aftermarket options. For a critical part like this, it's best to stick with reputable brands. Many owners and specialists recommend buying a complete kit that includes the belt, tensioner pulley, idler pulley, and a new hydraulic tensioner. Since the timing belt also drives the water pump, it is highly recommended to replace the water pump at the same time.
Brand Tiers for Dodge Stealth
- Tier 1 (OEM Quality or Better): Gates, Mitsuboshi, Bando. Gates is a very popular and trusted brand in the Stealth and 3000GT community. Mitsuboshi and Bando are often OEM suppliers for Japanese vehicles and are considered a safe, high-quality choice. Many owners stick with an OEM Mitsubishi tensioner even when using an aftermarket belt, as aftermarket tensioners have a reputation for being less reliable.
- Tier 2 (Reputable Aftermarket): Continental, Dayco. These are well-known brands that offer reliable products. Dayco belts feature a unique Kevlar weave and tooth design, but some mechanics find them stiffer and harder to install than other brands.
- Tier 3 (Economy): Cloyes and other lesser-known brands. While functional, for a critical interference engine, it's generally recommended to invest in a higher-tier kit for peace of mind.
Cost of Replacing a Dodge Stealth Timing Belt
The timing belt replacement is a labor-intensive job on the Stealth. The total cost will depend on whether you do it yourself or use a professional shop, and which parts you choose.

What is a "60k Service"?
🎬 Watch a complete 60k maintenance walkthrough for the VR4.The manufacturer's recommended service interval for the timing belt is every 60,000 miles. This comprehensive service typically includes replacing the timing belt, water pump, tensioner, pulleys, and accessory drive belts. Even if your car has low mileage, the belt should be replaced based on age (typically 5-7 years), as the rubber degrades over time.
Frequently Asked Questions (FAQ)
Were there any recalls for the Dodge Stealth timing belt?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls related to the timing belt for the 1991-1996 Dodge Stealth. Failures are typically due to the part reaching the end of its normal service life.
Is this a difficult job to do myself?
Yes, this is considered an advanced DIY job. 🎬 See how to replace the timing belt on DOHC models. It requires supporting the engine, removing a motor mount, and working in a very tight space. Setting the timing correctly across four camshafts (on DOHC models) is complex and requires precision. Mistakes can lead to catastrophic engine damage. It can take an experienced DIYer 8-10 hours.
Should I replace just the belt or the whole kit?
Always replace the entire kit. The pulleys and hydraulic tensioner wear out along with the belt. A failed pulley or tensioner will cause the new belt to fail, leading to the same disastrous results as a snapped belt.
What is the difference between a SOHC and DOHC engine for this job?
The main differences are complexity and consequence. The DOHC (Dual Overhead Cam) engine has two camshafts per cylinder bank (four total) to time, making the job more complex. It is also an interference engine. The SOHC (Single Overhead Cam) engine has only one camshaft per bank, is simpler to time, and is non-interference, meaning a belt failure will not destroy the engine.
