Coolant tubes are subjected to constant punishment and harsh engine conditions so it is very important to purchase replacements that are built to last. Reliability is everything when it comes to cooling and heating. Anyone who has spent time broke down in the middle of the summer can attest that dependable heating and cooling system is mandatory. All of our coolant tubes are stainless steel and reworked to remedy any flaws in the OEM parts. Purchase your heavy duty heating and cooling components from Raney’s and start saving. One of the worst and most expensive problems an engine can have is a leaky fuel reservoir so make sure you purchase quality replacements when it is time to upgrade. If your truck isn’t running you aren’t making money. The ever present vibration of the engine combined with extreme heat can really tax all of your engine’s fluid delivery systems. All of the engine parts Raney’s carries have been tested and built under the supervision of diesel technicians with extensive experience in identifying failure patterns, leaks and defects. We also have the coolant reservoir caps and level sensors as well.
