When to Service Your 1987 GMC S15 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC S15 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 1987 GMC S15 is essential for long-term engine health. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You could be on the verge of a radiator-induced engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from GMC S15 Radiator Repair

What’s included in a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your GMC S15. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

Issues with your radiator often coincide with a malfunctioning water pump. Some services for your 1987 GMC S15 engine can wait, but the water pump is one part that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. From the heater core to the radiator cap, we’ll take excellent care of your 1987 GMC S15 at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

GMC S15 Radiator Q&A

Wondering how to make your 1987 GMC S15 radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • What does an illuminated coolant temperature light mean for my GMC? Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.
  • Is an antifreeze leak dangerous? Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.
  • Do GMC S15 radiators need to be cleaned? To keep your GMC S15 radiator running well, it’s wise to get it cleaned out a few times a year.
  • What is causing my S15 to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your GMC S15 engine to overheat.
  • My S15 radiator sounds like it's rumbling or boiling! What's up? Your S15’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Is rust in my S15 radiator bad? Yes. Rust in the radiator of your GMC S15 can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
